souimanga commented 4 years ago

Hi all, I’ve noticed several times that the device doesn’t send data anymore. When I put a new battery, it’s working again. BUT the battery life is very short, maybe several weeks... is that normal ? Thks

yannoz commented 4 years ago

same here, after installing the plugin, the battery drain in two weeks, interval is way too hight, should be in days by default not seconds

souimanga commented 4 years ago

Ahhh thanks @yannoz I feel less alone ;)

honkmaster commented 4 years ago

I feel sorry, to hear this issue. However, my batteries last about half a year with the default settings. Thus, I think i am not able to help.

souimanga commented 4 years ago

Hi @honkmaster many thanks for your concern! It’s weird ! I will send all my version installed and settings, so you could maybe tell me what’s wrong ??

Is that possible to set measurements to only one scan per day ? @honkmaster I’ve again one battery empty...

My set up drains battery really fast as well, around 3 weeks in total. Really which there would be a way to fix this.

Same here. I guess the max limit of 600 is pulling data too often. My battery survives just 3-4 weeks. That's quite short

benschwarz commented 1 year ago

@bondskin, @Aekung, @souimanga did you manage to overcome the battery drain issue? Do you have recommended interval settings?

Looking at the documentation, the interval default is 600 (seconds) (10 minutes). A better default might be 43200 (12 hours). That way, there won't be an regularly active bluetooth connection, which should save precious battery power.

honkmaster commented 1 year ago

The interval is a for polling. It does not guarantee, that any data is received. If it is very long and the connection unstable, data will never show up.

bondskin commented 1 year ago

The outside temperature seems to be a huge influencer for the life time of the battery. I have the interval running at 3600 and it delivered results.
