ST Presence Sensor Battery Level


(Ahmed) #1

I have a ST Presence sensor on my key-ring. About 6 weeks ago I changed the battery on it. But now 6 weeks on it’s reporting the battery is already at 25% this seems like a ridiculously fast discharge rate. The original battery also lasted about 8 weeks or so. Is something wrong?

sadly it is normal. Workaround has been to solder a large battery to it, or wire car power to it, which works well.

That’s a shame. Is there any better presence sensors that have longer lasting batteries? I guess now that I know the battery doesn’t last as long, I could buy a big pack of batteries :slight_smile:

I’ve had these things running for over 6 months… it’s not normal.

In fact, my tenants just returned a fob that has been sitting in a draw for 13 months and it’s still pinging away.

What batteries are you using?
