Battery life Zooz Remote Switch ZEN34

Does anybody have any first hand experience on the battery life for the Remote Switch ZEN34? Thanks!

I’ve had one installed in my office for 2 years now. I use it daily as the primary way to turn my office lights on and off, and for some helpful scenes. It’s on a direct association to a ZEN72 that is not convenient to reach when entering the room. I only recall changing the battery on it once in all that time.

I only have the Zen37s in use, but for what it’s worth, I’ve had several going for a year, that still haven’t needed to be charged. Even the one by the front door that is used to arm the alarm.

The battery life on the battery operated devices has been quite impressive actually.
