Scheduled charging via OpenEVSE (time-of-use) does not start at the programmed time, though manual charging works.

Safety first: This is a functional issue, not typically a safety hazard.

• Step 1 – Verify clock: Check the EVSE's date, time, and timezone via LCD or web UI. Correct any errors and test scheduling again.
• Step 2 – Review schedule: Ensure the schedule is enabled, days of week are correct, and start/end times do not overlap in unexpected ways.
• Step 3 – Test simple window: Configure a simple schedule (e.g., start in 10 minutes, end in 1 hour) to see if it triggers.
• Step 4 – Firmware update: Update to the latest firmware version, which may fix known scheduling bugs.
• Step 5 – RTC check: If the time drifts significantly or resets, the RTC or its battery may be failing; replace the main board.
