Quite confident that the Homey community can solve this problem: I would like to use the surplus energy produced by my solar panels (with a SolarEdge converter) to charge my Elnur Gabarròn " [ECOMBI SOLAR SMART STATIC STORAGE HEATER FOR PV INSTALLATIONS](https://www.elnur-global.com/electric-storage-heaters/ecombi-solar-smart-storage-heater-electric-heating-for-pv-installations/?_gl=1*14hi7nj*_ga*Mzg1NjQxNjMuMTY0Njc1ODk5NQ..*_ga_WBN6VS4Z3P*MTY0Njc2MzAzMS4yLjEuMTY0Njc2MzM2Mi4w*_ga_JFBQMGWTX0*MTY0Njc2MzAzMS4yLjEuMTY0Njc2MzM2Mi4w)". Elnur provides an “accessory solar box” with power meters, but that would be a lot of work. My wish for a smarter and cleaner future is the following: - Homey gets the information about energy production and consumption from [the SolarEdge Appli](https://homey.app/fr-fr/app/solaredge.modbus/SolarEdge/) - It controls charging the Elnur storage heater via its WiFi connexion, i.e. allows charging when the surplus goes into the grid (the heaters automatically charge anyway if needed) - (and all that should be working with a three-phase installation) A promise: When an appropriate solution is found, I’ll replace my eeDomus for a Homey 😉 ---

In this [thread](https://community.athom.com/t/go-e-charger-electric-car-charger/14162/38) it is explained how the surplus of energy is used to charge a car. Should be usable for your storage heaters too ---

Great, thank you! What I would still need is an appli that controls the Ecombi storage heaters. They’re WiFi-connected, it should be feasible…
