LEDVANCE wifi socket

An Amazon bargain (9€), this socket also has power monitoring using a really nice chip HLW8012.
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.
Works fine with ESPHome
Button 13, relay 12, led 3, HLW select 14, CF 4, CF1 5

Panel move

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.

Ecostar garage door opener

The Ecostar garage door opener that I have is over 8 years old, so things may have changed. This ecological disaster of a design takes 8W on standby. And it's all down to a cheap crappy transformer that Ecostar have tested and accepted.

They have deliberately undersized the trafo, and it gets over-loaded albeit for a very short time when the door opens or closes. This is fine, but is a trade-off. The rest of the time it's on standby, waiting for the 2 or 3 times per week that it gets used. 

I know it's the trafo, as I found a 200VA unit in my junk box. It takes 2W on standby. So, really well done Ecostar for saving yourselves a few euro and killing the planet.

Fridge/freezer

 Picked up this gem a few weeks back


It's sold under loads of brands. Runs mains compressor or 12V peltier, but with no thermostat on the peltier, it consumes more power (48Wh) on 12V than mains, so I'll just use a small inverter in the car.

The compressor ran for 3 mins every 18 mins maintaining 0C (setting 4) with 18C ambient. That's ~8Wh. I'll have to see what it uses to drop to -15C, but will make a useful backup freezer, or overflow freezer in the summer when we have energy excess.

Winter tyres

 It's now consistently cold, so the tyres are swapped front to back.
