[RELEASE] Solaredge Monitoring Device Driver

Alan_F · September 13, 2025, 3:30am

I just noticed your post when this thread went active again. I pull the individual panel data using a Python script I found online that scrapes the SolarEdge web site and saves to a database. Since it's pulling from the website it can't get older data, only the last week at most. It's not subject to the API request limit because the script is accessing the web site, not using the API.

PM me if you're still looking to get the panel data and want the details on how I've set it up.

I noticed today that I was getting exceptions in my logs from this device, especially when I hit Refresh. It's the same error reported up above.

There is a pending pull request that fixes this:

## Fix: `GroovyRuntimeException` — Ambiguous `BigDecimal#minus` when API returns… null power values ### Problem During every polling cycle, the driver throws the following unhandled exception: ``` groovy.lang.GroovyRuntimeException: Ambiguous method overloading for method java.math.BigDecimal#minus. Cannot resolve which method to invoke for [null] due to overlapping prototypes between: [class java.lang.Character] [class java.lang.Number] ``` This is caused by the SolarEdge API returning `null` for power values (e.g. at night or when there is no production), which Groovy cannot resolve in arithmetic expressions on `BigDecimal`. ### Changes | Location | Problem | Fix | |---|---|---| | `querySitePowerFlowEndpoint()` | `PV.currentPower - LOAD.currentPower` crashes when API returns `null` | Extract values first using `?: 0` and cast to `BigDecimal` before arithmetic | | `querySitePowerFlowEndpoint()` | Missing safe navigation on optional `STORAGE` fields | Added `?.` operator on all optional fields | | `queryOverviewEndpoint()` | API can return `null` for energy values | Added `?: 0` fallback on all `sendEvent` calls | | `updateTiles()` | `device.currentValue()` returns `null` on first run before data is populated | Added `(... ?: 0) as BigDecimal` on all comparisons and `formatEnergy` calls | | `formatEnergy()` | Crashes with `NullPointerException` when `energy` is `null` | Added null guard at the top of the method | ### Testing Verified the driver polls without exceptions. Thanks for your work @funzie19 !

@funzie has not been around in 18 months. I hope they are still here!

Tag me if you need me. I no longer use Hubitat as I've moved to better HA solutions. Also don't have solar panels anymore. But happy to keep merging PRs to the repo. I get thousands of Github messages per day so they go the trash unless they are specifically assigned to me or tagged in them.

Thank you for merging that PR!

I use HA along with Hubitat. In fact, I checked this because of the latest breakage that was happening with the HA Solaredge integration (it was a completely different issue).
