Power consumption of Firmware



I noticed that the current firmware with the default settings consumes quite a bit of battery when running stand alone. I tried to change the settings to take measurements every 10 min and sending batches of 6 measurements to the website. However, in that mode the power consumption did not change for the better, I even got a worse power performance.
What would be the best setting for long term measurements? I am looking to take measurements every 10 min or so…



Hi Reimer,

Thanks a lot for your remark in power consumption.

In theory, if you change the settings of the two lines below in Constants.h tab, the power consumption should change:

#define DEFAULT_TIME_UPDATE “60” // Time between updates
#define DEFAULT_MIN_UPDATES “1” // Minimum number of updates before posting

If you you increase the time between updates and the minimum number of updates before posting, the power consumption should be less than with default settings.

I am going to run a couple of test on power consumption here in the lab to double check this and I will also ask the team for information about this topic.

I will let you know as soon as I have news.

All the best,


Hi Reimer,

Sorry for the delay in getting back to you on this topic. I been really busy progressing with other stuff. I hope you understand. :slight_smile:

I have just set up three SCKs with different update times:

Right now they are all connected to the mains. As soon as the battery is 100% in all of them, I will disconnect them from the mains and I will be aware of them to see how the power consumption goes.

I will get back to you later.

All the best,


Hi Reimer,

I hope you had a nice week.

We have readings for our test but need to analyze in deep the graphics. It is gonna take time. You can help if you want! :slight_smile:

I have seen irregular behavior on the beginning of the slopes but at the end the register makes sense. With less update time the battery last longer. The dead of the battery is at 26.3% in all of them. I need to talk with the team about all this. :wink:

We will make more lectures on power consumption soon.

All the best,


interesting! Thanks Aitor.
