Anything else?

Having a similar issue here: Since yesterday I did not get any data from my Model S and I cannot send anything to it. via HA. Possible that the connection to the Tesla servers seem to be interrupted? Anyone else having this issue? For me it looks similar to the API thing at the start of this year.

I have had the same issue just now (in addition to all powerwall sensors not updating) and performing the same fix here resolved it - perhaps this is a regression: #919 (comment)

I am on v3.24.0
PWG v24.12.6 3cc46fb9
2x Powerwall 3

Similar but subtly different issue. Lots of Task exception was never retrieved (might be nice if the integration catches internal exceptions and sets itself to an error state or similar?), but the traceback is:

...
home-assistant  |   File "/config/custom_components/tesla_custom/sensor.py", line 445, in native_value
home-assistant  |     return round(self._energysite.energy_left)
home-assistant  |                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
home-assistant  |   File "/usr/local/lib/python3.12/site-packages/teslajsonpy/energy.py", line 152, in energy_left
home-assistant  |     return round (self._site_config.get("nameplate_energy") * self.percentage_charged / 100 )
home-assistant  |                   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~
home-assistant  | TypeError: unsupported operand type(s) for *: 'int' and 'NoneType'

which I believe means that nameplate_energy is an int, and percentage_charged is None -- whereas in the initial post about this issue, it looked like it was None and float. Could be the exact same issue just different python version/impl reporting differently, but it's odd.

I ended up getting my integration working again by replacing
return round (self._site_config.get("nameplate_energy") * self.percentage_charged / 100 )
with
return round (self._site_config.get("battery_count")*self._site_summary.get("percentage_charged")*13500/100)

in the energy.py of my local copy of teslajsonpy.

Right, the nameplate_energy value is also missing for me in the energy site API payload.

I have a PowerWall 3 with software version 24.44.2 a6ea90d1. See also be bug report here: zabuldon/teslajsonpy#342

When I comment out the inclusion of TeslaEnergyBatteryRemaining in sensor.py, the integration is working as expected:

tesla/custom_components/tesla_custom/sensor.py

Line 96 in 3760ff3

entities.append(TeslaEnergyBatteryRemaining(energysite, coordinator))
