Charging_Amps

[israndy]

You have a note under the Commands section of the TeslaPy readme that I hope you can update:

requires car version 2021.36 or higher. CHARGING_AMPS can be set to less than 5, by calling the API twice.

I have been working with this for my App TesSense and noted thru experience but have not seen anywhere on the net that if you try to set the amps to 2 it will set them to 3, and if you try to set them to 1 or less it will set them to 2

So 4 amps = 4 amps, 3=3, 2=3, 1=2, 0=2, etc.

I had hoped in my solar Tesla charging app that I could actually set the charger to 0 amps instead of turning it off, for times like around sunset so the relay wouldn't keep flipping on and off as the solar power waned, but I will have to come up with another strategy, or live with the 2 amps charge rate until the sun is officially down

In fact, it is useless to go below 4A because the base consumption of the vehicle during charging is too close and the efficiency of the real charge is low with a lower amperage. Anyway, great app. Respect to the developers.

Which is probably why Tesla set it up the way they did, but my point was that the documentation is wrong on TeslaPy and hoped I helped clarify

I find I get different results with different connectors.

With the UMC, if I set charging_amps to 0 it actually stops charging and drawing power from the socket.
With the HWPC and TWC, if I set charging_amps to 0 it only goes down to 1 or 2 amps and continues to draw power.

I have three phase power on my TWC (pity the API says 2 phases), but at 3A x3 phases = 9A I'm getting the same as a UMC, so don't write off all the values below 5A. I also find it really useful to match against solar having the lower ranges. If I was limited to 5 A x 3 Phase x 240V = 3,600 W, which is hard to have excess for a standard 5 kW solar inverter. I would love to see some API results when using charge on solar, but that isn't released to my market :-(

UMC:

TWC (gen 3):

Interesting, which UMC are you using? I have the portable charger that came with the original Model S and I get different results from the ones you show, 0 means 0 for mine, then 1 = 2 actual, 2=3, 3=3, 4=4 and so on

I have the Gen2 UMC that came with a 2020 model 3, it is capable of upto 32A single phase.

I understand the Gen1 UMC came with earlier model 3 and could support upto 40A.
