I hadn't seen this one before. The 30 minute Agile charge slot at midnight was not actioned. WW log said
Error setting charge schedule: There was no response from comms. Please try again [i9tYcZq1]
I checked the GE log and this had
2025-03-10 23:59:47 You AC Charge Enable There was no response from comms. Please try again true true -6 API - Inverter Settings - Wonder Watt - i9tYcZq1
2025-03-10 23:59:12 You AC Charge Enable There was no response from comms. Please try again true true -6 API - Inverter Settings - Wonder Watt - i9tYcZq1
2025-03-10 23:58:54 You AC Charge Enable There was no response from comms. Please try again true true -6 API - Inverter Settings - Wonder Watt - i9tYcZq1
2025-03-10 23:58:41 You AC Charge Enable There was no response from comms. Please try again true true -6 API - Inverter Settings - Wonder Watt - i9tYcZq1
So it looks like another failure scenario is when the comms. between the Inverter and the GE server are broken.
30 minutes later and the commands were getting through fine.
PS Other things on my network were fine at this time so I don't think my network failed.
