Transmitter battery drain

[hognefossland]

Hi Ondrej1024,

Thanks for your excellent work on this application. I've set it up on an Raspberry Pi 3 to monitor my daughter's blood sugar levels. Her pump is a 640G.

I had been using the Android 600 series uploader, but wanted a solution that would be permanently powered, and your solution is perfect for that.

However, since starting to use DD-Guard, the Guardian 3 transmitter battery no longer appears to be lasting the full 7 days. Instead it runs out after only 3-6 days.

Due to Covid, my daughter has been spending a lot of time at home and is being monitored pretty much 24/7, whereas previously we'd use the Android solution only during the night (for nearly three years), so this might be a contributing factor.

It's only been a few weeks at this point, but I'm curious whether you've ever noticed any battery impact from using DD-Guard. Of so, do you have any suggestions as to what night help mitigate the issue? Presumably reducing the polling rate will improve the situation.

I did come across a thread on the 600 series uploader that also seemed to suggest there might be an impact on the batteries from using these tools, though I'm struggling to understand how the transmitter battery (rather than the pump battery) would be affected.

Any insight would be much appreciated.

Thanks, Hogne
