I found a pack of 5 on Amazon for $20, for each of the sensors and the esp32’s… so $40 for 5. Probably cheaper in Ali or similar. The only negative is they need some calibration. The ones from Adafruit are better quality and already calibrated, but much more expensive.


I already had influxdb+grafana setup, so it was easy to pump data to, plus I was able to then match it up with cpu temps and such from my Kubernetes nodes. I like having all my data in one place.
That said, Tasmota has native Matter support and I now have a few ESP32’s controlling sockets, lights, etc., that integrate with Home Assistant.
