This one came with a ESP8265 chip, which I programmed using ESP01 settings.
Very similar to this https://devices.esphome.io/devices/LEDVANCE-SMART-PLUS-PLUG-EU
Soldered a wire onto GP0 on the rear of the module.
Ground and reset to enter boot mode.
The odd, unrelated events in life, living in the Baronnies, in the south of France
Moved the panels between 4pm and 7pm. More power in the evening and less in the morning.
The roof slope means more generation in the summer, but the same annual generation overall. The house is pointing SSW, so power starts later in the morning (~30 mins later) but as the panels are now higher, the power ramps up quicker.
