It is left to the user to detect and manage over-voltage and under-voltage conditions before the battery just stops (those same two resistors again), detect battery overheating, and to manage returning to operation when the battery has sufficiently recharged.

It does have Over Charge/Over Discharge/Over Current/Reverse Connection Protections but not extra bells and whistles beyond that.

One thing I wished I thought about more carefully at the outset is that the v1.1 I’m using only has 1A output, which is really stretching things if you want to power a small pump…

I guess this is the reason you changed to reporting in your on_boot: routine (so you can go to deep sleep soonest).

Yes I manually take control of updates to try to do them efficiently within a minimum wake window then go back to sleep.

which again assumes/requires that all processing has been done in the time allocated.

Probably if the sensors aren’t all updating in a reasonable time (say 20 sec) then something is wrong (sensor is not working) and you probably want notice of that before going back to sleep so it doesn’t just stay awake and drain battery waiting for offline sensors which aren’t going to update. Can try again on next wake cycle. That was my experience/thinking.

If they all update before that upper reasonable value then go back to sleep asap.
