I bought a neo coolcam door sensor on the recommendation of forum members and it was very reliable and fast so I bought the second one to put on my main door.
The second one worked well for a few weeks then one day it started to not work.
I restarted Homey and it worked again, so i thought was a one time thing.
The next day the same problem occured, when I open and close the door to go out it worked but when I came back the door contact alarm didnt notify.
So I unpaired the sensor and repaired and while it works… after a few hours it will become nonresponsive again. But then I went to developer’s panel and i saw this.
Currently the door sensor still works but why is the flag “offline”. Trying to heal or send basic on messages gets error.
The exact same door sensor I have the bathroom door one has no such flag.
I doubt it’s a zwave coverage issue since it is very close to Homey (the bathroom one is further).
Edit : I switched the door sensors I had (and renamed approriately), surprise… the other battery sensor now doesn’t have the flag “offline” even at the same position at the main door.
While the original door sensor (now renamed to bathroomdoor sensor) that was at the main door now placed in the bathroom has “offline” flag. It doesn’t appear to be location related, but something to do with the sensor itself, one of them is always “offline” regardless of position.
Any ideas? For those of you with neo coolcam door sensors can you help by going to https://developer.athom.com/tools/zwave and help me see if your neo coolcam door sensor has the flag offline.
