    Smart Blinds - my wife doesn't care so sharing it with you guys

    Spent few days making my blinds smart, my wife didn't care in the end as it was expected lol, however I really like how it ended up. Now I have even more automations !

    https://i.redd.it/ep9ymqtq88s61.gif

    P.s. here is the short tutorial I put together https://github.com/ialex87/smart-blinds

    Any feedback is welcome!

    80% of my HomeKit stuff just crapped out on my for no reason, and I AM DONE! What can I replace this BS with?

    Posted: 09 Apr 2021 11:24 AM PDT

    I am so frustrated with all of my HomeKit accessories. I have a mix of different light switches, bulbs, garage door opener and thermostat, speakers on my "Home" app.

    The WORST offender has been the Ikea smart hope stuff! Every couple of months for some reason I have to RESET everything, and now either some iOS update or me moving an AppleTV and some speakers has basically disrupted the connection somewhere and all of my stuff has started to fail.

    I am just DONE with everything being connected to my wifi network and relying on 3rd party servers, with things mysteriously just not working anymore. I have also used Homebridge to get compatibility with some devices.

    WHAT can I use / buy that is going to be more stable? Something using Zwave? I would rather have / make a hub (I raspberry pis available if I can use those) that I have more control over AND keep individual devices off of my wifi?

    Thank you! I kind of just need to rant, but would also like suggestions and I love all the posts in this sub.

    Can’t get myQ G040 to connect to Genie 2028

    Posted: 09 Apr 2021 11:31 PM PDT

    I got the process down right, long press until both lights flash blue, press once more so one purple light flashes, press remote button so both purple lights flash, then try to connect via app. But just won't connect.

    Has anyone had success with this exact model (2028)? I'll try support next week. It seems like it should work, but also seems like it's very hard to make it work.

    Lots of conflicting info about which myQ works with which Genie, and with which steps…

    I know some folks don't like the myQ, that's fine, but I don't want to spend a bunch more money for something with a worse app integration, or something I have to wire. So feel free to tell me myQ sucks, but I'm just looking for anyone who had success with the 2028.

    So smart lights (like Hue) retain colour settings when operated with a regular switch?

    Posted: 09 Apr 2021 10:59 PM PDT

    I'm looking into building my home automation setup and I've realized that I don't need as much control over everything as I originally intentioned.

    I would like the ability to change the colour of lights from time to time but don't want to use the app or voice control to turn off and on all the time.

    So if I set the colour on a light such as a Phillips Hue, and then just turn off and on with a regular wall switch will it retain the colour settings or do they have a "default" colour?

    Follow up question; are they instant on or is there is any delay experienced with them?

    Thanks for the help

    Smart switches for new home

    Posted: 09 Apr 2021 10:47 PM PDT

    I'm building a home and have let the builder know I want all the light switches to be Lutron Caseta.

    Now that I'm thinking about it, I'm wondering if I should have some of them be regular switches. Do I need to be able to turn the closet lights on/off from my phone? Do I need to turn the fan above the toilet on/off with my phone?

    With 51 light/fan switches in my house, I'm not sure if I want to pay that amount to get all these smart switches.

    Do I get them all for consistency or should I only get smart switches for main living areas?

    Smart Switch recommendations

    Posted: 09 Apr 2021 07:43 PM PDT

    I have 3 GE In-wall Zwave switches (14291) currently… and one just died 😔 After some Googling, it looks like a common problem with these switches after a few years. So… I think I am going to replace all 3 now. I don't need Zwave, as I am slowly trying to get off of ST, so I could do WiFi ones, if possible. I really only need Alexa support.

    What are y'all recommending nowadays??

    GREE+ Sapphire mini split is now controllable via Google Home

    Posted: 09 Apr 2021 01:42 PM PDT

    I have had a GREE Sapphire mini split with Wifi for a while now and have been SUPER disappointed by the lack of features--the Wifi could only be used if you were _on the same Wifi network_ which seems utterly pointless to me... why even go through the trouble if you can't control from beyond your home?

    Well I had to update the wifi today because I got a new router and noticed that it can connect with Google Home Assistant. After spending 30+ minutes getting the mini split onto my network (curse you, Gree!) I spent 1 minute connecting it to the Google Home app and was able to say "Hey Google, turn on Mini Split" and it did it instantly. Woohoo! This actually makes my mini split function (almost) the way I expected it to from the beginning.

    Caveat is that it still only can turn on and off through Google Home... no setting temp or anything like that. But here's hoping they'll add that feature soon!

    IP Security Camera with reliable human detection

    Posted: 09 Apr 2021 08:51 AM PDT

    A couple of days ago we were victims of a robbery. 3 of our bikes got stolen from the parking lot, where I have a camera and two motion sensors. The camera was useful to record a beautiful video of the thief. The movement sensors turned on the lights so the thief could work with ease. Everything in my automation system worked as planned yet nothing really helped (us).

    Why didn't I have an alarm bound to them you might ask? Because of false positives. Dogs, cats, and moths are always triggering those sensors.

    I bought a Dahua Camera to check it out (my previous one was a 10 yo d-link). I was surprised when I set up the ONVIF integration on HomeAssistant and found out the camera provides binary sensors that I can watch on HA and use them to trigger automations, in real time!!!. It also has IVS that lets you define rules for human presence and enable a sensor for each rule. WOW!!!!!!....

    So good......., yet failed. Dog and cats were considered humans by the IVS which ruined everything, and where those rules are defined, there is no selector for sensitivity.

    So the question is: Is there an IP camera with ONVIF (now a must for me) that has a VERY VERY VERY reliable human detection?

    Tuya/Smart Life smart switch question

    Posted: 09 Apr 2021 05:19 PM PDT

    Hello! I just received my smart switch (2 gang) my only question would be if it's possible to wire up the live wire for it (its a no neutral one), with no load wires, and just control the bulb entirely through software, or if it's not possible, and wire up my bulb normally on the L1, can I use the other button (which should be L3) to turn off a smart plug?

    Turn on cameras / notification when dog barks

    Posted: 09 Apr 2021 09:24 AM PDT

    Hey everyone,

    I have one of those small annoying dogs that barks whenever there's some activity outside the house that isn't normal (people coming to the door, waking around the house etc.) it's usually annoying because he can't get more specific than "bark bark", but in general it's a good instinct and much better than the motion detection etc on most smart cameras. So, can anyone think of a way which I can trigger something whenever my dog starts barking? The goal is that I'd hook the trigger into an automation which takes pictures / videos from all of the cameras and sends me a notification with the pics / videos.

    Thanks in advance

    Help with recess lighting controlled by 1 switch.

    Posted: 09 Apr 2021 07:34 AM PDT

    So in my kitchen they have hooked up 4 recess lighting on 1 switch. I want to convert 3 of them to hue bulbs and convert 1 recess into a pendant light drop with this.

    Then thinking about it, light switch has to be on all the time, so my pendant light will be on all the time.

    Can a smart switch save me or do I have to rewire how the light functions?

    Cheap Chinese relay for electric blinds. Avoid? Alternatives?

    Posted: 09 Apr 2021 04:18 AM PDT

    My blinds are already electrical, controlled by just two switches: up and down. I found some dubious quality modules that are supposed to allow for connecting these switches to home assistants. Something like this: https://www.amazon.es/MOES-tapparelle-oscuranti-elettrico-compatibile/dp/B08L39B81T

    I'd probably get the cheapest from AliExpress just to try. Should I avoid it? Is there a better way to achieve this?

    Shelly Bypass Wiring

    Posted: 09 Apr 2021 11:45 AM PDT

    Shelly Bypass Wiring

    Hi, I'm trying to add a Shelly bypass to an old fluorescent light, however I'm unsure on what the proper wiring for this type of bulb, it's a little confusing. I've included images of what I'm working with and the wiring diagram.

    Edit: I am using an LED bulb and have tried using a Shelly 1L, but when the switch is in the off position the light flickers.

    Any help with this would be greatly appreciated! Thank you.

    Alternative to Alexa for simple local voice output only?

    Posted: 09 Apr 2021 10:15 AM PDT

    I'm using Hubitat and I know I can make Alexa speak, but my goal is to get away from my dependence on Amazon and I'm wondering if there is a product like a simple local only speaker that can be used to send output text to? My needs are basic, I just want something that can be triggered to speak when things happen, but don't need the ability for myself to talk back to it. Does such a device exist?

    Do you know the 4 Types of Routing Mechanisms of ZigBee Protocol?

    Posted: 08 Apr 2021 11:06 PM PDT

    Do you know the 4 Types of Routing Mechanisms of ZigBee Protocol?

    ZigBee routing has the following 4 categories

    • Table Routing
    • Broadcast Routing
    • Multicast Routing
    • Many-to-One/Source Routing

    Part 1 :Table Routing

    In order to discover the path to the target node, the source node first sends a route discovery request to form a routing table. When the route between two nodes is established, the source node only needs to send data to the first node in the route, which exists in the source node's routing table.

    So each intermediate node forwards the data to the next node in the route by querying its own routing table until the data reaches the destination node. If the route fails, the routing error is sent back to the source node, which can then re-initiate the route discovery request.

    Part 2 Broadcast Routing

    Broadcast routing is a routing mechanism that sends messages to all devices in the network. Network layer broadcasts have the option to choose whether messages are sent only to routing devices, to non-dormant end devices, or to end devices with dormancy.

    The following table, set by broadcast address

    https://preview.redd.it/gjvz818493s61.png?width=731&format=png&auto=webp&s=8de3209916b2192de3ef4e5d05f2cc36422858ba

    A broadcast message is repeated 3 times by all routing devices in the network to ensure delivery to all devices. While broadcasts are a reliable method of sending messages, they should be used with caution due to the impact on network performance.

    Repeated broadcasts may restrict other ongoing communications in the network. Broadcasts are also not a reliable way to send messages to dormant devices, as the parent device is responsible for buffering messages that are sent to dormant children device, but it may drop messages before the dormant children device wake up.

    Part 3 Multicast Routing

    Multicast routing provides routing options for one-to-many communication. Multicast is used when a device wants to send a message to a group of devices, such as a switch sending an on command to 10 lights. In this mechanism, all devices join into a group.

    Only those devices that are members of the group receive messages, while other devices will forward these multicast messages. Multicast can be interpreted as a restricted broadcast, likewise, excessive use can degrade network performance, and there is no ACK for both broadcast and multicast.

    Part 4 Many-to-One/Source Routing

    Many-to-One Routing is a simple routing mechanism that allows routing devices throughout the network to have a route back to the central node (concentrator), where the central node (concentrator) periodically sends a Many-to-One route discovery broadcast (which takes 60 seconds in default but can be set on demand).

    When a routing device in the network receives a broadcast, the routing device has the next-hop route back to the central node (concentrator) and stores this hop node information in its own routing table. Therefore, whenever a routing device in the network receives a broadcast of Many-to-One route discovery, it knows the route back to the central node (concentrator).

    As shown in the figure below, C periodically broadcasts Many-to-One route discovery, and all routing devices in the network know their own routing information to C and update it to their own routing tables at the same time.

    https://preview.redd.it/ofo5ra5693s61.jpg?width=525&format=pjpg&auto=webp&s=b79846126626ce343cb03da59874ab9e983a5b4f

    Source routing, is the routing mechanism that the central node (concentrator) send messages to other routing devices. For the central node (concentrator), it does not know the downstream route, that is , the route for sending information to each routing device is still unknown. Therefore, when each routing device sends a unicast to the central node, it sends a route record to the central node beforehand. The central node receives this route record, reverses this route and stores it in the Source routing table of the central node (the table needs to store the source routing information of all routing devices in the network). In this way, the central node can query the source routing table to obtain the routes sent to the destination node.

    As shown in the figure below, when R1 sends unicast data to C, it will first send a routing information of its own to C. When C receives the routing information from R1, it will store the route in reverse to its own source routing table, and similarly the source routing table will record the routing information of all routing devices in the network.

    https://preview.redd.it/z4fuoo0793s61.jpg?width=486&format=pjpg&auto=webp&s=9da5dc424443e2fa3c2d0be2157ef12cfb9b260d

    In short, as long as the routing device receives the Many-to-One route discovery broadcast, it knows the route back to the central node. As long as the source routing table of the central node has the information of the routing device inside , the central node knows the route sent to that routing device.

    If the central node (concentrator) is reset or rebooted under abnormal conditions, all information in its source routing table will be lost, in the meanwhile a corresponding mechanism is needed to recover its source routing table. In this case, you can make the central node (concentrator) broadcast Many-to-One first.

    route discovery, and then broadcast a data to each routing node, so that the routing node replies a unicast to the central node (concentrator), the routing node will send route record before sending this unicast, so the central node can update its source routing table.

    If all routing nodes are powered off or restarted in some abnormal situation, the routing table of each routing node will also be lost, and then it is necessary to wait for at least 16s after each routing node establishes a link with neighboring routing nodes, and then the central node (concentrator) sends a Many-to-One route discovery broadcast, and once each routing node device receives the Many-to-One route discovery broadcast, it has a route back to the central node.
