Sorry if this is a newb question; I’m coming in cold. I’ve had HAOS running on an RPi4 for months, but I haven’t invested in any smart devices to connect yet.

I’d like to start with some (ideally open source) smart gauges just to check the temp out front and back. Any recommendations?

Thanks!

      I’m a bit late, but if it helps, I’ve had good results with the Sonoff and Tuya zigbee sensors. I prefer the Tuyas, just because they use AA instead of CR2032 batteries.
      $50 will easily get you everything you need to start.

      You might also want to think about getting a 433MHz radio for the system.
      If you live in a built up area, you’d be surprised how many people have equipment transmitting on 433MHz already (free data!).
      And a lot of generic wireless temperature sensor kits use it as a standard, making it a good value way to get weatherproof gear.
      I got a generic fridge/freezer kit for about £10 that works perfectly with this. Again, $50 or so for a DVB-T2 receiver. Just be aware that it’s a little more technically involved than pairing zigbee devices.

      Bother me with DMs if you like, I’ve been fiddling with just about every protocol I can get my hands on for under £100!
