No new updates on Will's firmware post and I'm not being offered anything in the App to upgrade to.
Out of interest, what are you being offered as an upgrade?
The firmware update feature for the inverter seems to be turned off for my H1-6-G2 - no longer says "latest" or have a red dot indicating upgrade available next to version numbers... Still says "latest" next to the logger firmware.
I think this occurs when they "pull" a bad firmware release. It should come back once it is stable or they have a valid update.
