How can I add watts data to solidgeek?

Hi guys

I've made a dyno to test electric motors, well at the moment I'm testing the output of a converted alternator. I'm using solidgeek code with arduino on the uart port and have erpm for converting torque in to hp but would like to add watts being used so I can work out the efficiency. Any help would be much appreciated! Here's a link to my YouTube video, I've added the mechanical kw conversion to the code after this video

You can use SolidGeek library as an example, look how other data is received and processed here:

https://github.com/RollingGecko/VescUartControl/blob/008f89efc916009d266...

For example:

values.ampHours = buffer_get_float32(message, 10000.0, &ind);
values.ampHoursCharged = buffer_get_float32(message, 10000.0, &ind);

Then you would modify the library to include new data from what VESC is sending.

Wh used, for example, are here:
