  • Part of the problem here I think relates to scale.

    If I invite a load of friends over to my house for a party, they might be in different rooms having different conversations but they’re all my friends in my house. No one cares who I let in or kick out, certainly not either of the next groups.

    Let’s say I’m part of the committee for the local community hall. We let our halls out to clubs. Some of the committee go to some of the clubs. I might not be interested in what it is, but if someone I trust says they are OK, I’m OK.

    At the local University they have a lot of spaces, each managed by the respective school. Each school has a slightly different ethos. Some of them might let their space to groups that other schools wouldn’t, but it’s not their call. They share some resources but not decision making.

    We’ve got this problem emerging. The decisions made by lemmyworld or other large instances are generally in service to their communities, whereas on smaller or more focused instances the instance level decisions are the same as community level decisions.
















  • I’ve been using HA for a long time. I love that it is capable of aggregating all the data sources and orchestrating all the different sensors that are on the market. I haven’t used everything below, but I have used a lot of it and can give some pointers.

    Instead of a Conbee II I would suggest the Sonoff Dongle. I reached a point when I had a lot of devices that the conbee couldn’t quite keep up.

    I have smart bulbs from ikea, innr, linkind, Aldi. They all paired to the zigbee mesh pretty well. I also had some Osram ones that didn’t behave as relays so I took them out.

    The BT sensors look nice, and I believe they integrate with HA well, but your HA needs to be in BT range for them to be able to communicate. You could also look at the Sonoff environment sensors. I use these tucked away in different rooms and they are great.

    Cameras, the general advice is to make sure they support RTSP and ONVIF, with brands being Hikvision, Dahua or Amcrest. Everyone will say you should feed your cameras into a Network recorder first, with options often recommended being BlueIris, Frigate. I use Frigate.

    Feel free to ask any follow up questions, I’ll do my best to guide.



  • I’m currently in the middle of a renovation so my HA instance is down, but let me give you some pointers. I think it’s possible but it’s getting right into the guts of what makes HA powerful (and complicated)

    Firstly, template lights this is how you can surface a light that reads values from other elements and presents them as light settings.

    Then the attribute you want is rgb_color and you want to parse out the red value (for the red channel) and convert it to a brightness for the template lamp.

    Lastly you’ll need to work how to update the red value of the led strip when the brightness of the light changes. This will involve pulling back the green and blue values of the led strip and updating the strip’s rgb_color with the combined list. this page has examples.

    I’m sorry I can’t give you any sample code but this hopefully gets you started.
