The "Classic" charge controller / Re: Getting a classic to commu...

VERY nice!

Curious. Please accept apologies for basic nature of this question.

Would I run the Cat from the Classic to the Cerbo or the router that HA belongs to?

For the Classic data to get to the Home Assistant it will get it off your local internet network. So as long as you have the Classic plugged in to your local network and HA on the same network , the the ip address you put in for the classic should find it. If I remember correctly the Classic only lets you have one connection so if your HA is getting the data via ip modbus, then you won't be able to connect to it with another program like Local Status app.   
So the answer to your question is the Classic to your router.  Once you find out the IP address the router assigns to the Classic and everything is working, I would go to the setting in the Classic network section and make that Ip address static. And also reserve that address in the router too .

MNGP2 specific / NEW Production Firmware 26.01....

Last post by aaapilot - March 01, 2026, 01:46:15 PM

Production Firmware 26.01.05.00 has been posted on the server for download.  As usual, took several attempts to get it, several Block errors stopping the download.  Check the Beta posting for what this release contains, affects both the Hawks Bay and Barcelona controllers.  Running on my 2 systems w/HB & Classic controllers and no issues that I've noticed.  Good luck!

Go to Settings/ Devices and Services in HA
add modbus to Home Assistant
Then add this to your HA config ( change to your classic IP adress )
modbus:

    port: 502

the victron part or classic to home assistant part?

My goal is to try to get the Midnite Classic 150 information to home assistant. The app discussed above seemed like it might be helpful since it ported information to the Cerbo which also collects the Victron information. If there is another way other than Solar Assistant to get the information to HA, that would be helpful as well. It had been a while since this was discussed so was wondering if there were any updates to the app.

Sounds like a cool feature. Have there been any recent updates to this project?

which part of the project are you asking about - the victron part or classic to home assistant part?
