SolarEdge says its Monitoring API V1 will retire in November 2026. What are other Home Assistant users planning to use for solar and battery data?
I tried the local SolarEdge Modbus Multi integration as a fallback. It reads my SE7600 inverter and WattNode meter, but it cannot see my LG battery: direct read-only probes of all supported battery register blocks return Illegal Data Address.
So local Modbus is not a full replacement for me—no battery SOC or battery power. Has anyone found a workaround, had SolarEdge enable those registers, or started using the new V2 API successfully in Home Assistant?
Thanks for the heads up as I had not realized this.
I spent a little time researching this, and although I could not find a specific pull request saying HA supports the new V2 version…
There was an issue raised about this (here) that was closed saying it had been fixed.
I took a look at the latest solaredge library (here) that HA uses and comparing it to the new V2 changes (outlined here), particularly the new OAuth2 scheme, which the library now supports…
It appears that the new v2 is already being supported (not 100% sure, but maybe 90% sure).
