Eneloops would only last about 3 weeks. And disposable last 2 months. This door is used a lot and since it has Zwave and a door open sensor it sends info on every open.
Bonus, since it can handle the lipo AA batteries that put out 1.8v and it gives the motor more oomph I made the battery pack give 7.2v and it never sticks anymore.
This is a garage-door so its not critical access but is used a lot.
Does 1.1v not signal low voltage? How long does it work for after that? Could you set up an alert so that the moment it changes you get a text message? Or a light turns red or something?
Just curious. I haven’t played with HA, though it’s a long term goal.
