I bought the Aqara contact sensors. I turned it on and HE was able to discover it.
Is there a way to test it out? I can't get any responses from it.
The only thing I figured is that the "sensor battery is 0%".
Is it actually a battery issue?
Would the device be discovered if the battery were in fact 0%?
I've tried taking the battery in and out with no change
If I replace it with a new battery and it actually changes the description to 100%, is there a good way to confirm that the contact sensor is working appropriately?
You probably need to install a driver for those. There isn't a built in driver as far as I am aware. Use the table in the first post in the link below.
Yes, once you have the User driver installed and configured for that device you can close it then open it then click the Events button at the top of the device page to see if it shows the close and open events from a few moments before. If so you should be able to use the contact for HSM or any rules you want.
