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?
I feel like your best bet is ESPHome and the ESP family of devices. Last time I checked you could get the parts for a project like this off Amazon (with spare parts) for under 20$.

I agree if your diy an esp32 and a dht11 could easily handle those duties.
I use one with 2 DHT11s and two DS18B20s to monitor my HVAC temps.
