I’m in the process of building a custom terrarium that will eventually house a leopard gecko. I’m looking for some small, inexpensive devices to monitor temperature and humidity in the tank via Home Assistant so I can set up some alerts. Any recommendations?
Wouldn’t any off the shelf temperature+humidity sensor work? I use Sonoff and Aqara ones with Sonoff Zigbee coordinator and Zigbee2MQTT, both are somewhere around 15€ a pop, integrate painlessly and do the job. Aqara is a bit smaller and has air pressure sensor, too.
I agree with this, unless you paticularly want to do it yourself. You could even get a couple for redundancy for und
Sonoff SNZ02 for a small coin cell device, or Tuya if you want to use AAAs. (Tuya ones are a little cheaper too)
Edit: A bonus one if you also want a screen in the tank: Sonoff SNZB-02D.
