When I installed the ST Multipurpose sensors on my doors, I configured them as ST sensors. I’ve never used the temperature feature (being they are on the doors, they don’t represent any of my indoor temperatures) and I don’t use the vibration feature (I had a vibration alarm that was reporting too many false alarms).
What I’ve been wondering - if I take some of this functionality out of the code, or configure them as plain contact sensors, would I expect any better battery life? I don’t quite understand how polling works in relation to battery life and if this would make a difference.
My first one appears to have died after 8 months. It was reporting 50-some% one day, and the next it stopped working. Swapping batteries has it working fine again.
