How to add battery and tempe data to datafield?

Former Member over 8 years ago

I'm creating a datafield to display all the info I like to see in a custom display, but would also like to be able to view the battery percent and temperature in the corners of the display.
I can see the computer(info) function is passed an Activity.Info object, which I shall be using for all my speed/time data, but it doesn't contain either battery or temperature. So in theory I shouldn't be able to, yet I have seen it working in some third party datafields, such as:

Any ideas please?

Temperature isn't available to data fields (no access to Sensors, and that's where you can get it), unless you want to do your own ANT+ calls.

Battery, is easy though..

In the data filed, you just need to use Sys.getSystemStats().battery

You can get the battery percentage like so:
var batPct = Toybox.System.getSystemStats().battery;

6374

You can get the battery percentage like so:
var batPct = Toybox.System.getSystemStats().battery;

That sounds good - I'll try it tonight! Don't suppose there's a similar trick for temperature? I do realise it may be trickier due to having to use a sensor..

Doh - missed this post. Thanks for the info!
Looks like I'll just have to go without.

I wonder how the standard temperature datafield does it..

It's not CIQ and has access to it. Like I said, in CIQ it's in sensors, which you can't access in a DF. You can in a widget or watch-app though..

Thanks Jim! A font of knowledge :)

You could use the MoxyDataField sample project as a guide for adding the Tempe as a Generic Ant channel. It would require a few mods, but the principle is all there. It also shows how to save the data in the FIT file.
