I really enjoyed reading this, thanks for posting. I've been struggling to find a more sustainable solution on my end for all the sensors and buttons I have set up. Anecdotally I feel their battery life tends to be shorter based on whether they're in busy locations or not. I've ordered the CR2477 and CR2450 batteries they use in bigger quantities but I'd much rather be able to recharge them instead. Have you ever found devices of this type that allow them to be recharged?

Have a look online for LIR2450s. They are rechargeable button cells.

I have been using ZWave motion sensors that have USB input so no battery required, for buttons I have replaced a lot of wall switches with Tasmota switches that are programmed for single/double/hold click actions on multiple buttons. This can be great on multi gang switches where I have one button control the relays in all three switches, leaving two buttons open.
