Works great out of the box, easy to fully integrate/adopt into Home Assistant with ESPHome Device Builder. I will definitely buy more sensors from here in the future.

Great little device

Ordered three of these to monitor temps in my basement fridge/freezers. Easy setup, imported and configured in Home Assistant… exactly what I was looking for!
