 TesSense  -Randy Spencer 2022
 Python charge monitoring utility for those who own the Sense Energy Monitor
 Uses the stats for Production and Utilization of electricity to control
 your main Tesla's AC charging to use excess production only when charging.
 Simply plug in your car, update your info above, and type> python3 tessense.py

 Added: another minute to remove powering off due to spurius spikes/clouds
 Add: reporting the Tesla's charging to Sense as if plugged into a TP-Link/Kasa
 Add: ability to find TP-Link devices on the network and control them.

Yeah sure thing! It's definitely helped me make some improvements to SenseLink.

As for it waking up the car, there is a way to query the Tesla API in such a way that it doesn't wake up the car, but I think it might have to be via the streaming API. Unfortunately it seems like the Teslapy docs on streaming are a little light/nonexistent. I gather that if you use the streaming API it doesn't wake the car up, but you can tell if it is awake you can then query it like normal. I have telsamate set up for myself, which I can verify doesn't wake the car up.

Oh, it’s not that I can’t let the car sleep, that’s easy, just check if it’s online and if not don’t call SyncWakeUp(), it’ll stay asleep. The problem is if I see there is LOTS of free solar and wanna see if the car can use it I NEED to wake the car to find out if the battery is full or if it’s even plugged in. If neither of those are true I can just let it sleep, but won’t know if the conditions change. Or will I? I did the trick running Sentry Mode all night and the car never slept, which is fine, saves the High Voltage Relay, but if I DID plug it in than the car would be awake for 15 minutes, so I could just set a variable if the car is full or unplugged to NOT wake it up until the car is woken by being plugged or unplugged. Genius. Thanks! I never would have figured that out if you hadn’t said something.
