charger turned-off for unknown reason

[troullll]

hi, a few days after some different situations, I have this new issue (30 traces only so I can't check it), any idea ? thanks

[ddaddy]

Sorry, I only speak a little French so don't fully understand your screenshot. At 09:40 I doubt there is sufficient solar to charge?

Also, the lines about the charge latch seem strange. Could you have had a very brief power cut?

[troullll]

ok, charger turned-off at the top of my screenshot, turned-on at the bottom. so weird...

yes, 1 spare Amp at 9:40

yes, I always have those lines asleep / charger door / port latch why Asleep is "on" ? it seems Polling doesn't work... how could I check if it works ?

[troullll]

could we add a Wake-Up or Force Update action before any Tesla Smart Charge automation ?

[ddaddy]

I think them lines run backwards? The most recent at the top.

I have already added some Polling automations which reduce the polling time during the day. Have you installed them?

[ddaddy]

Also, I think that when a command is sent to the car, it is woken up and all data refreshed. That is handled by the Tesla integration.

[troullll]

installed and tested, Polling Time effectively change. the Charger sensor is not up to date when automation runs it ... ok, data is delayed by the polling itself, but I really think when the Tesla is deep "Asleep", we should add a binary_sensor.charging check, to ensure automation isn't changing amps as the Tesla effectively is not charging, it happened some times

[ddaddy]

Ok, as my car never sleeps for some reason 🤷‍♂️ (An old Model S) I never see this issue. Reading the instructions for the Tesla HA Integration again, I see that it doesn't intentionally wake the car up. The only way to do this is by sending a command like 'lock doors' and this wakes the car.

I'll add to the automation, that if the car is asleep, send this command instead of doing any of the charging actions. Then 10 seconds later when it runs again, it should have the data it needs to proceed with charging.

[ddaddy]

This would actually mean, that as soon as the sun comes up, the automation will wake the car up and then it'll likely never sleep again during the day if it's at home. Is that ok?

[ddaddy]

Ok, i've added what I think is a better workaround. If the automation wants to start charging:

Enough spare amps to charge
Charger is off
Battery level is below charge limit

and

Car is asleep

Then it will just send the Wake Up command to the car.

Then when the automation runs again after 10 seconds, the car should be in a state ready to accept the charge requests.

You'll need to go through the file again and replace all occurrences of jess with your car name and setup your variables etc..

[troullll]

got it. I think when the Tesla start to charge at 1A, it stays at "starting charge", so binary_sensor.charging stays off. I set the minimum_start_amps at 2, and it is ok. Anyone else ?

[troullll]

oh sorry, I had not seen your answers, I'll check that !

ok ,good idea

ok anyway

ok, I'll check this, thanks

Ignore my first 2 comments as i've made it only wake the car if the automation is actually wanting to start the charge. And I also found the 'Wake Up' button in the integration, although the docs suggest you have to send a command to wake up.

If you find it not waking up, let me know and i'll change it to send a door lock command instead.

[troullll]

yes I'm reading your changes. BTW, do you think the charger latch thing is an issue ?

[ddaddy]

I don't know what would cause that. I would suggest a power cut, but it seems to happen too often for you.

Maybe try setting the minimum charge to 2a instead of 1a.

[troullll]

yes I already set the minimum_start_amps at 2, and it is ok to get the correct charger state. I copypasted your Wake Up changes (minus Jess), I'll test it tomorrow hehe

[troullll]

sorry, same thing this morning . why does the option 2 did turned off the charger switch ? I checked the "option 2" code :

• conditions:
  • condition: template value_template: "{{ spare_amps >= minimum_start_amps }}"
  • condition: state entity_id: switch.charger state: "off"
  • condition: template value_template: "{{ charge_limit > battery_level }}" sequence:
  • data: name: "[Tesla Smart Charge]" message: >- Charger is off and we have {{ spare_amps }} spare amps. Attempting to start charge action: logbook.log
  • choose:
    • conditions:
      • condition: state entity_id: timer.turn_off_car_charger state: active sequence:
      • target: entity_id: timer.turn_off_car_charger action: timer.cancel data: {}
  • target: entity_id: number.charging_amps data: value: "{{ spare_amps }}" action: number.set_value
  • target: entity_id: switch.charger action: switch.turn_on data: {}

[ddaddy]

I don't know 🤷‍♂️ There is no code there to turn it off.

Do you have any other automations that might turn it off? Does it only happens once in the morning, then everything works ok after?

[troullll]

indeed on the trace of your automation ! how ? btw, I suspect the charger switch bug. I manually turned on the charger this morning, and it switched off itself 2s after. Wondering if it's caused by a Tesla Integration bug, as the interaction on our Tesla Apps is Start Charge OR Stop charge (buttons) and not a switch neither a toggle... I will perform these tests : alias: test switch toggle description: "" triggers: [] conditions: [] actions:

[troullll]

it happened twice more this morning (after few seconds)

[ddaddy]

If the charger turns off after 2 seconds when you manually turn it on then it can't be an issue with this automation.

Try disabling all the polling automations, the charging_off_when_plugged_in automation and all the others like the Stop charging at sunset.

disabled all these ones wait and see
