I have the Keypad YRD240. I just paired with ST I see it but don’t respond any command. Don’t send any log at all. I just unpaired, try it again same deal. I unforced same deal. I restore the keypad to default try it again same deal. I don’t think will be out of range I have like 5 devices less than 10’ next to the keypad.
I just bought this week, but never work at all, just always show locked, when I try to unlock just unlocking nothing happen, and then I refresh the page. and show locked again.
I just bought the Yale ZigBee 240 this weekend. It did not work with the batteries provided. The included batteries showed 43%. Once I replaced them with brand name batteries everything started working.
Edit: Wanted to note that I had the same symptoms you described. I had no problem pairing the lock but after that point it would not respond to commands or update state until the batteries were replaced.
