Battery life on Shelly Motion sensor not good

[Adsibob]

We have some Shelly Motion sensors rigged up (wirelessly) to a Shelly Plus 1PM that’s connected to a pump. Although it was a pain to set up and configure, once I got it working it has worked flawlessly for the past 3.5 years… except for one thing: in the last 18 months I’ve noticed that the battery life has gotten worse. They used to last a year before needing to be recharged. But over the last 18 months the life post charge has got shorter and shorter. Looking at my logs I see that it reported low battery three times in the last 9 months, so I’m getting an average of 3 months per charge.
 

Wondering if anyone else has experienced this. Looking at the webstore it appears they’ve discontinued the particular product I’ve got, which was simply called “Shelly Motion”. Maybe this is why.

Seems others have had similar issues but I couldn't find a recommended solution. Some say firmware, some say WiFi range etc.

I wondered if something was trying to talk to it too frequently increasing power consumption due to increased WiFi traffic?  

 

Found this on that last link above..
