Dear,
I am a complete newbie with Homey, and I need some guidance for the first project for my parents.
They live in a house that used to be heated solely by heat-accumulators (they used to have a special contract for the accumulators). (model: Dimplex CXL S24N)
Location: Belgium
Since some renovations they also have a gas fireplace.
They currently have solar panels with a non hybrid inverter.
They also have a Mercedes PHEV.
The plan is to:
-convert to dynamic energy contract (power by the hour)
-install an hybrid inverter (probably Growatt) with 10 kW of battery power (and a smart meter)
-install a homey compatible smart thermostat
What I want to achieve (all through AI and smart usage of the dynamic contract):
-charge the heat-accumulator during the cheap hours (mostly during the night, if needed around 12h we also have a pricedip)
-charge the boiler at night and with any excess solar production
-charge the PHEV at night
-charge the battery at night (if no or little solar is expected) and use the battery for all electrics untill we are back at low cost energy
What I think I need.
Homey Pro
DIN Rail Smart Switch for charging the heaters at night
DIN Rail Smart Switch for the boiler
Smart Plug for the PHEV
Questions:
-what app is the best to use to predict the solar production (no need to charge the boiler/PHEV if the next day the sun will shine)
-can Homey/the smart thermostat “calculate/adjust/learn” how much we need to charge the heat-accumulators at night in order to have a good temperature during the next day?
I still need to check if the Gas-Fireplace can be automated (to use it if it’s cheaper then charging (recharging around 12h) the accumulator, offcourse it’s always a good backup!
Thanks
Tanguy
