Community report: Powerwall 3 charged at peak rate after tariff error
Unconfirmed: A Reddit user in the UK with a Powerwall 3 (PW3) on EDF's Electric Go tariff says that, when starting and stopping an export from Home Assistant, the system began charging at peak rate. According to the post, the app showed the grid buy rate as 0p. Attempts to re-integrate the tariff time out, although Home Assistant retrieves data from the EDF API without problems. The post does not include firmware version or configuration details, nor any response from Tesla or EDF.
- UK user reports peak-rate charging after an export started from Home Assistant.
- Buy rate shown as 0p; tariff re-integration times out.
🔎 Why it matters: No official confirmation from Tesla or EDF: the report describes an Electric Go tariff error on the Powerwall 3 tied to the Home Assistant integration, with no firmware version indicated.
📈 Upside: Not applicable.
📉 Risk: According to the report, a wrongly recorded buy rate led the PW3 to charge at peak rate during an export started from Home Assistant.
