The "Classic" charge controller / Re: Classic data on Home Assis...

Last post by ClassicCrazy - April 08, 2026, 10:20:13 AM

Sorry for the delay. Since I'm new to writing code as HACS integrations, I concentrated on the easy stuff. I'm now looking at the ability to write on some Classic's registers. Just need to figure out which ones I should start with. I also need to consider extra validation/safety to make sure no garbage ends up in the registers.

BTW, any preferences in the registers you would like me to start with?

Now that I think about it , maybe just easier to use the Midnite Local Status app to write changes. But keep in mind that there is only one modbus ip to Classic at a time. So if anyone wanted to use the Local status app when your monitoring is running it won't connect . Graham of Classic DIY on github had his monitoring app have a delay in there somehow so if the Local Status app was turned, it could butt in and get the connection. Otherwise if your app had an easy way to disable that would work.
But if you want to experiment with writing maybe start with something like Absorb Time or Float voltage - things that wouldnt mess up a battery too much if they goofed up. What would be really nice is if you could put limits in so that it wouldn't be able to write a value that was way off.
One of these days I will try your app - just a matter of time cause I have too many projects going now!

The Rosie / My QD7500 charges my batteries...

Last post by bigbillsd - April 08, 2026, 10:20:00 AM

This is a JFYI to anyone on the fence like I was prior to buying the Rosie.. It WORKS!   

I am using the latest Rosie firmware.  (i had not tried it with any other firmware, but had read there maybe issues with my 2006 Quiet Diesel Genny in the motorhome)  It was set to use 26AAC which appears to be the maximum.  (my genny is only 120v x 2 so I could not get double that) as I would when connected to 240v from Shore Power or I my genny supported 240v Split Phase.

Lithium / Eco-Worthy Rack Battery Comm's...

Last post by bigbillsd - April 08, 2026, 10:08:22 AM

After many days of trying all sorts of Solar Assistant (SA) configurations and cables plugged into many different ports I finally got SA to show all 4 batteries in my pack yesterday.  (mainly thanks to Ryan as he mentioned ModBus was supposed to be what works on a call)  Everyplace I found mentioned using USB JBD...  That gave you just one battery in the pack. 

I tried a RS485 Cable purchased from Eco-Worthy (on eBay).  Plugged it into the RS485-1 port (leftmost) on the 1st battery in my Pack, Then in SA I set the battery to be "USB Modbus RS232/485" it almost immediately found it and connected and showed my all 4 batteries in my pack. Of course I had to pick the correct connection for that USB to RS485 connection in SA. 

Hopefully this helps others keep more of their hair intact.. I have also documented this on DIY Solar forum and Reddit.

Local App software / Re: Local Status Panel will no...

Last post by SDman - April 07, 2026, 12:49:05 PM

CC

Cross checked IP addresses on the Local ap and Classics and they match and are set to DHCP. 

As for the Local ap software, I have done that one as well, deleted and re-installed and no bueno and no other monitoring software being used for the Classic (didn't know there was any other software out there).

But...lo and behold....the usual IT response was required....unplugged the cables from the Linksys switch and replugged and....at least one is reading (AND POPULATING ) which was the most important thing to me (the Classic).  With the Lite in "follow-me" mode, life is good.

Was chasing this whole thing as getting ready to upgrade the LA batteries to LFP's.  Yes, know the Classic does not communicate w/the BMS, but just easier to change/chase parameters via the AP vs. at the display.

Now off to review battery options for my system.

Appreciate the input as gave me a moment of pause to just do the "simple" things.

Local App software / Re: Local Status Panel will no...

Last post by SDman - April 02, 2026, 11:01:33 AM

CC - thanks for some ideas.  Will give it a try over the next few days outside chores on backburner due to weather, thus inside shop time projects to attend to.

Will status update if changes (or not).

Thanks,

SDman

Local App software / Re: Local Status Panel will no...

Last post by ClassicCrazy - April 01, 2026, 07:41:56 PM

I haven't used the local status app in awhile. Seems like what I did i the past if I ever lost contact with them was to delete the old ip address in the app, set the ip in Classic to DHCP , and let the router find it again. Then when it is back on the app , you can go in Classic MNGP and make whatever IP address static again. Also do the same for in the router you use  - reserve the IP address so it doesn't ever give it out to something else again.
If none of that works, maybe try delete local app from your computer and reload it again.
Also - just in case you just started using some other monitoring software for the Classic - the Classic can have only one ip connection at a time . So if there was other software being used , then the local status app won't find the Classic until that other software was disconnected.

The "Classic" charge controller / Re: Classic data on Home Assis...

Last post by ClassicCrazy - April 01, 2026, 04:39:51 PM

If it can help, I just finished a Home Assistant custom component that can read pretty much all the Midnite Classic's registers and more and create corresponding sensors/entities in Home Assistant that can be used to control and chart stuff and feed the nice Sunsync power flow chart.
The custom  component is in GitHub at https://github.com/qcda1/ha_midnite_classic

At installation, the user can select the values he want to be created as entities in HA from a total of 54 from which 11 are selected by default. The sampling period can be specified from 30s to 1 hour. The Classic must be on the same LAN than HA and a host name should be configured as this will be the name of the equipment in HA.

Here is a sample installation picture:


Regards,

Daniel.

did you build write commands in that to be able to change setting or do something like force bulk or float , etc ?
Your project looks good though I haven't tried it because what I have above in first post  is working for me now.
