I have a Tesla Model S, charging from a NEMA 14/50.(40 amp) (vs. the high power wall connector at 80 amp)
The problem I have isn't Sense related, as much as I'm wondering how Sense can Sense the Tesla, as you can set the charge amps to any number, up to 40 on the outlet, or 80 on the HPWC.
For you see, The S will auto reduce charge amps, based on voltage. I will set my S to charge at 40 amps. It loads up the breaker slowly... amp by amp up to 40/40. It's very recognizable on the graph/chart.
My issue (and why I'm wondering about the detection of the car) is that after a while at 40 (takes me on average 2-3 hours/night to charge), it will kick down to 30 amps! It does this because at some point the Voltage drops to what the car feels may be an issue, or wiring issue, or who knows. It keeps the car and wiring safe. The real issue, after months of replacing things, testing, etc. Is my Power company... Who installed a monitor on my meter, and claims "It's all good"...
However they gave me a 8.5 x 11 with a whole week on it! Not down to the second like I need to prove they can't hold 240v at my house...
I'll let everyone know if/when my S shows up, but for now it's set to 35 amps, so it doesn't end up knocked down to 30 amp. (car is working properly, charges at full 40 amps at other houses).
I actually logged my Sense experience on the Tesla forum as well: https://teslamotorsclub.com/tmc/threads/get-some-sense.81046/
