Hmm… interesting, thanks!
I have a support case open with Shelly at the moment… my batteries are dying “too soon” (in my vague opinion)
A recent battery died at 71% - that ran for ~2 weeks , so I am NOT impressed with that…
They are reporting that it is a firmware issue (I updated it ~1 or 2 weeks ago when I changed batteries), but that isn’t clear whether “70%” should actually be “0%”, (and a 2 week battery life is to be expected)
Whether the device is using too much power
This particular sensor is at the far end of the wifi signal, and in a room whether temp (& humidity) change fairly often, so I think this one is particular “busy”, but even so… 2 weeks! Other sensors are definitely lasting longer, but I really don’t like the idea of using 1/3rd of a battery’s capacity
I’m even thinking of getting an external rechargeable AAA battery pack and wiring that in… looks terrible, but for the money I’ve spent on sensors, I’m not wanting to spend that much on batteries!
So… apologies, I’ve hijacked your original question and I don’t have an answer for you
