sounds like you are carrying them around. If you can leave teh fobs in the car then you can permanently power from car battery. Identify an always-on circuit in the car (like door locks, but don’t use door locks if you’ve got another circuit less essential).
THere is a greater chance of running the car battery down if you leave the car sitting a long time. Also they occasionally malfunction and draw more juice than expected, running the battery down faster. If your battery is in bad shape to start with, then this addition can help you buy a new one.
Nice idea… It would work IF I lived in a single family home… but the fact is I live in a 6th floor, and the garage is 2 floors underground… no way the signal can get thru! So I need something else… I tried the smartthings app, but I don’t want the cleaning company to have permanent access to my lights/HVAC!
My iPhone phone “arrives” a few seconds before the fob. I think I’ve seen 2 versions of fob. A round one and, like mine, a small rectangular one. Which do you have? Mine is at 88% after 6 weeks assuming the reporting is accurate.
right now no “hurry”… BUT I do plan to have an alarm system… and it should deactivate itself upon arrival… It wouldn’t be nice to have the siren go off at night because the batteries ran out… would it?
