Has anyone upgraded their IQ Panel 4 to 4.2.1? Any known issues (currently on 4.1.1)?
4.2.1 just has a single fix for an issue which affected a handful of systems regarding overheat shutdown events. 4.2.0 added a number of new features. See the log on the firmware page.
I’ve added 4.2.1 to the firmware page, linked below:
