I don’t know how you would do either piece of that. None of the Sense applets have a input path for amending Sense data.
The only options for supplementing Sense mothership seem to be:
- spoof the behavior on an existing integration (Kasa, Wemo, Hue) to offer a new device data stream. @dpt was investigating this route here
- Use a second Sense or the auxiliary port on your Sense. But a second Sense won’t combine the data into a single account, and the aux port on the Sense is only allowed a fixed set of monitoring/combining functions today (solar, generator, dual panel)
- Merge the data outside of Sense using export. I do this to enhance my charging data for a weekly usage plot.
You can Tesla get charging data from apps like TeslaFi that do use the Tesla API and OAuth 2.0 Authentication.
