I bought 2 MYGGSPRAY. I’ve been using them for about 3 months now. They show up as 100% on Home Assistant but is it showing the wrong numbers or is it just sipping the battery? How about your experience?

If you used lithium rechargeable batteries it may stay at 100% until the batteries die, since the buck converter presents a constant 1.5v

    On that note: do not use these type of batteries for smoke detectors. Most will not be able to detect that the battery is about to die, and just stop working one day
