Fibaro Smoke Detector Battery

Got a low battery warning, replaced battery it still shows 5% tried another new battery and same thing. I created a device handler, triple clicked the smoke detector hit configure within the simulator in the hope of forcing an update but still shows 5%. Surely I could’nt have got two dud batteries? Any ideas appreciated.

I find with the Fibre’s that you’ve got to wait about 24 hours for the battery voltage to get registered - not sure if other z-wave sensors are like this

Thanks for advice I’ll see if they update tomorrow. Does seem mad that it’s not instantaneous. Cheers

Yep. I replaced like for like. So hopefully it’ll update with full capacity…

When you change the battery, once removed press and hold B button for 3 seconds - 100% Battery!!!
