I get a strong sense there is a secret tunnel full of antiques behind that wall…?

In Europe red are usuallly the cheap PVC ones while black has higher quality insulation and last much longer, well worth the price difference.

My solar is going up next week, so I’ve been experimenting a bit with working it into my current setup. I have import and export data from my smart meter, hourly electricity price from entso-e and a simulated solar production based on the lux reading from my outdoor pir sensors. To get real time production I specced an elko smart tag energy meter on the fuse for the inverter, as the solis is not easy for an amateur to get data out of. I also have smart relay on my water heater, and have been controlling this based on electricity price for a while now. I’m also working on adding the heat pump and bathroom heat, they will be set a couple of degreees lower when power is most expensive, and a couple higher when solar is produsing to “store” heat. Not sure how all this will work out yet so I’ll not share the details before I’m sure it works, but I hope it gives som ideas.

For visualizations I use apexcharts, i can fit solar production, consumption and price with and without grid tariff in a single card, althought it’s not quite perfekt yet.
