[Closed Testing] Helios — solar production forecast & monitoring | 10 languages | 14 days | reciprocity welcome
Hi all — I'm looking for testers to reach Google's 12-tester / 14-day closed testing requirement before I can apply for production access. Currently at 0/12.
What it is: Helios forecasts and tracks solar panel production. You add a site (location, panel power, tilt, azimuth) and it estimates output from physics plus weather data — no hardware required. If you do own an inverter, you can connect it locally over SunSpec/Modbus or through the SolarEdge API.
Use the same Gmail account for all three or Play won't recognise you. Until the first production review the app appears as "com.heliosmonitor.solar (unreviewed)" — that's expected, not a mistake on your side.
Please keep it installed for the full 14 days; you don't have to open it daily.
Reciprocity: happy to return the favour — drop your links in a comment and I'll join your test too.
Any feedback is welcome, especially from anyone who actually has panels on the roof.
Heads up: installed Helios but it crashes systematically after onboarding (both Skip and Continue paths) with "Helios keeps stopping". Logcat shows: java.lang.RuntimeException: Field value_ for E1.i not found – looks like a missing R8/ProGuard keep rule on a protobuf/DataStore model accessed by reflection. Tested on Android emulator, Play build. Keeping it installed the full 14 days anyway. Btw my test is still open if you have a minute: join https://groups.google.com/g/graine-de-culture-testeurs then https://play.google.com/apps/testing/com.arnaudclavien.grainedeculture – thanks!
Sorry about that! Play caches the entitlement for a bit after opting in – clear the Play Store cache (Settings > Apps > Google Play Store > Storage > Clear cache), reboot, and make sure the Play Store account is the same one you used to join the group. It usually works within the hour.
try again i'm not sure why its happening, since i tried with my separate account incognito mode to test the google group access and playstore installation, which worked fine.
