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

Last post by ClassicCrazy - April 08, 2026, 10:51:58 AM

You can get Grahams Classic Monitor here ( for android -maybe version for iphone too )
https://github.com/ClassicDIY
It used to be available on Playstore but not sure if it is now.
That won't write changes though.
Yeah I didn't think of rebooting the router - good idea !
For batteries look at Eel and Yixiang MB31 eve cell options that have jkbms v19.
They have stock in usa .
Look up Off Grid Garage on Youtube - he did detailed video on building above though I think they are also shipping in completed batteries now.
Also Docan is an option but the above two are better .
Classic if fine with lithium once you tweak it's settings a bit.
I don't use closed loop even with controllers that can do that.

The Rosie / Re: Pros and Cons of Closed/Op...

Last post by FNG - April 08, 2026, 10:37:25 AM

Which simply doesnt happen when using open loop and a shunt, because the shunt can detect much smaller currents.

I will be using a repurposed BMV 712 shunt.  That is also something I will need to get into SA.. 

I did try connecting my ECO's to the Rosie just now.  The MGNP does now give me SOC so I am thinking it may be working.. sort-of  Nothing in SA anymore for the battery. 
I do not seem to have a way to terminate the bus now,  I plugged in the SA RJ45 into the MGNP second port and I plugged in the batteries into the Second Port on the Rosie.  Now I am wondering how I can terminate it as there are no more ports on the CAN bus.  I was googling a hub but not seeing much except stuff dedicated for certain printers.  I was thinking I needed termination on Both sides.  But it looks like it may be working without termination.  Not a lot of Canbus errors on the MGNP.  At least they do not seem to be incrementing up.  I am thinking I am only seeing the First ECO battery.  Each battery has a CAN port.  Maybe I need to daisy chain them.  But not sure how yet.  There are a lot of ports on the front of the batteries.

I connected the Rosie CAN port to CAN on the front of the battery and it seems to see one battery.  Then I added 3 more Twisted Pair cables, from the RS485-1 to the battery below's CAN port, same for the next two hooking up all 4 batts.  I am pretty sure I am still only seeing one battery in the MGNP2 and SA.  I saw Ryan's example and he sees all 4 of his batts.
If you see the IN RS485 Out ports on the right, I am using that for the EcoWorthy Battery monitor screen.  But they are not RJ45 connecting, look like the 4 or 6 wire RJ's   



 

Just to add to this, When you plug the battery in to the canbus it does the termination on that end. And the solar assistant also terminates on that end so no extra terminations are needed

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.

I got it working and posted how in the Lithium Battery section this morning.

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

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...

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
