I'm looking into maybe using the new batrium core and MM8. This will be a 16s2p setup with two MM8s. I was wondering if anyone know if the Batrium talks to the Growatt over CANBUS? I don't see it advertised on their website but I know the Growatts are just a brand name - Should I be looking for a different name?

Let me know how it goes. I did see the RS-422 protocol pdf around (looking for it) so not sure if it uses the same registers as the CANBUS

Might be interesting - Actually nevermind - This is for talking to the battery not the growatt protocol. Still I guess you could use some glue on a RPI to join the two together

MM8 cannot be used on 16s. https://support.batrium.com/article/354-options

Yeah has Batrium been working on that or any results back??
I have not had time to work on this with all the other issues that have occured. Once I can get everything back online I plan to pursue this.

any updates so far 6 months later ?
I'm still waiting to get everything resolved, my watchmon core was defective on arrival. It got lost for 4 months in the mail. I sent it back to AU about two weeks ago and it arrived safely. I'm hoping to get everything fully working and then do the zoom meeting.

Thanks for the update - Australia must be outer space considering 4 months in the mail, lot worster than china even in the bad days of the early 2010 where it usually seems to got lost till it appeared out of nowhere.

Good luck !

I sent them and email just to see if they had an update on the watchmon core, but its only been there for a few days.
It was suprisingly not to expensive to ship to the AU. It was constantly stuck in an error stated, we tried flashing, full resets etc.
