I love using this companies products. I’ve had a reed sensor in a dirty hot chicken coop for over a year, 200feet from the house and I still get instant feedback on when the door opens. The battery life on their current products is fantastic. I have one sensor attached to our garage door and another to the blinds to let me know when they open or close based on the angle of the sensor. The hub supports local URL calling so I don’t have cloud delays on integrations with my automation systems. Here is their latest product. I’m keen to try out rules based on the ambient light levels.

Sorry, After re-reading this I realize it looks like an advertisement.
The one product I can’t recommend, however, is the plant water sensor. It works fine for temperature but the moisture sensor would flood me with push notifications when it was on a notification threshold.
