Hi,

I can see in my APP a FW version is available. Are there any release notes?
This for a H3-15 SMART inverter.

Shows -

Master 1.39 > 1.44
Manager 1.24 > 1.26
Slave 1.0 latest
AFCI 0.35 latest

Anybody upgarded - what are the benefits?
Again where do you find changelog or release notes so can decide whether or not it makes sense to upgrade.

Thanks

Release notes are here, but I don't think they have updated the list for a while now.

Will has a list also, but with basic notes only

Thanks

I found then prior as well. No information in either.

Pretty poor from a manufacturer, their SW team develops the SW release, test it, provide report on features/changes/additions/bug fixes to the Product Manager and then the PM develops the release note and publishes it. Well that is how a normal OEM works :o

@JA my H3-15 is showing the same from/to versions as your initial post. Did you end up either finding any RNs or doing the upgrade? Comments if you noted anything from the upgrade?

No I didnt find anything - Fox seem to be pretty hopeless in that regard.

I havent upgraded as my system seems to be okay and I would never upgrade not knowing what new features, added limitations and bugs have been addressed in a new SW release.
