Master not matched error - firmware update offered in app
My H1-6.0-G2 is on Manager 1.69 and Master 1.51. This morning an update was offered in the app to 1.70 and 1.53 - however if you click update in the app it fails immediatly with "Master not matched". Is this an issue just with my set up or is it a problem with the update flow ?

Same for me,
Master 1.51>1.53
Manager 1.69>1.70
Error Code: -1, Master not matched
Re: Master not matched error - firmware update offered in app
Seems to be some firmwares are being pulled by Fox.


Not matched mentioned here for a KH firmware update, but the error is same (Master not matched)

It will be a wait and see if you can update later next week.

I noticed this as well yesterday. I am also getting errors -1, -26 and -27 which started mid afternoon yesterday, but nothing seems to have tripped. Resetting hasn't fixed anything either. Waiting to see if whatever the issue is with the firmware is also causing the other issue.

Observing same issue and not found a way to clear the error

I raised a ticket and they have updated it to the latest firmware and so far so good

I've been nervous to do that as I now notice that the firmware update has been pulled from the app (notification of installation error is still there). There have been some reports of the firmware causing issues . Glad it's working smoothly for you
Re: Master not matched error - firmware update offered in app
Fingers crossed this is what it’s on now;

H1-5.0-E-G2
Master 1.53
Slave 1.04
Manager 1.70

My installer has said they need to send someone out for a nice fee. I may try raising a ticket first directly with foxess

Yes I would, they got back to me within a day

So yesterday the app offered the update again and successfully updated. No issuesso far - same versions. Not been able to see if this fixes the forced discharge logic issue.
Re: Master not matched error - firmware update offered in app
There was an issue where manager v1.70 required master v1.53, looks like the app was trying to update the manager s/w first.
H1-3.7-E-G2, 2xEP11-H and 6Kw solar
Manager(ARM):1.70
Master:1.53
BMS:1.012
