User reports Powerwall 3 blocked from grid charging after 26.34.3 update
Unconfirmed: A Reddit user reports that his Powerwall 3 stopped charging from the grid during Intelligent Octopus Go off-peak hours on Saturday night. Until then, he controlled charge and discharge cycles with Home Assistant, Predbat, and the Tesla Fleet API. He had switched his import tariff from Octopus Agile to Intelligent Octopus Go the previous Thursday. According to the author, the Powerwall had updated to firmware 26.34.3 f2e0e391 the day before. He mentions achieving at least one successful attempt before the block.…
- Overnight charging block reported on Saturday, with no official confirmation from Tesla.
- Firmware cited by the user: 26.34.3 f2e0e391, installed the day before the failure.
🔎 Why it matters: Unconfirmed: the author attributes the Powerwall 3's overnight grid charging block to the 26.34.3 f2e0e391 update, applied one day earlier. The switch to Intelligent Octopus Go also happened that same week.
📈 Upside: Not applicable.
📉 Risk: If the link to the update is confirmed, Fleet API automations that charge from the grid could stop working on updated units.
