Add a zigbee outlet or switch to your garage to ensure you have solid zigbee signal in your garage. A solid zigbee mesh from your garage to your hub to help ensure consistent presence detection. Then add an upgraded presence sensor to your car.
Soooo, I’m supper annoyed with the presence sensor battery life… so this is what I’m doing.
Since a CR2032 battery is 3v and ~240mah I figured I could take two AA batteries in series to get 3v and 1900mah capacity. HUGE difference! about 8x the capacity of a 2032 battery setup.
I purchased a few battery cases with leads and project boxes. I’ve already made one for my motorcycle and popped it under the seat. So far, so good. I just want it to last more than 3 months! If the increase in compaticence is even a lowly 50% efficiency gain, which I am guessing it’s far more than that… the thing should last more than a year. If the efficiency is closer to 100% then I can probably expect 2 years out of this thing.
I plan on making 2 more for my car and my wife’s car. What I do is set up …
You should have very little lag w/ this setup.
