I have problems adding a Neo coolcam keyfob.
Things i allready have done
Install beta version of the app
Disbale all other zwave apps
Restart Homey
Adding really close to Homey (less then 10cm)
Rest keyfob by holding the SOS key for more then 10seconds
Keep pressing buttons will adding
When you want to add him to the homey you need to stand ver close to you’re homey. Then push the sos key fast 3x when the light one you’re keyfob doesn’t blink red you need to put in new batteries. I had the same probleem because i tried to add the keyfob to far a way from my homey and that drain the battery within a few minutes.
Unfortunately I had the same issue with Homey and could not solve it. Currently I run now also Home Assistant with zwave2mqtt. One was working directly and the other one I needed to remove and reinsert the battery to get it working in combination with zwave2mqtt. In these setup I did the same actions on the keyfob’s. In my opinion it is something to do with Homey (base or app NEO Coolcam).
