Battery drain



I find that the batteries of the Fibaro door sensors V2 drain very quickly. I have one here that gives it up after a month = €€€. The configuration is on the default setting except Parameter 2  = Visual LED indications = O.

I also have a V1 + DS18B20 in a garage without heating and without insulation with a lot of temperature difference (even below 0 degrees) and this battery lasts much longer.


Any tips, experience?


V1 = Z-wave protocol = 4.5

V2 = Z-wave protocol = 4.38

HC2 = 4.532 beta

    Can I check how many times the sensor talks to the HC2?

    Hi, [email protected]


    I've also had a Fibaro Door/Window V2 Sensor, it was very unresponsive and multiple batterys have been drained in a few days. I got it replaced by the reseller. The new one is OK.


    Best Regards
