Yes, as mine is running on a PI, with a small touch screen.

I don't get dealer pricing at Revov though 😀 The Fox aren't badly priced, maybe I just upgrade to 2 stacks for the upstairs house. Works out at 92k for 40KWh. HV though, but I can rejig my system to support.

Just checked Segen, I see the Revovs are around 12k ex vat for the 5KWh units. so 24k ex vat per 10KWh I'll be finishing off my house end of 2025, and plan to add another 40KWh of battery, so that's nice Current wholesaler pricing below - I assume you'll get similar pricing that I will.

Be aware., I've had them swap out batteries on both units under warranty already. That said, fairly painless as they came out and swapped and gave a replacement unit while they confirmed that it was a bad cell in the pack. I could see it as the per cell values on my monitoring made it obvious, but they still took 2-3 months to check /replace at the time. The price differential at the moment doesn't seem worthwhile to go for 2nd hand cells, it's cheap enough now to go new, and the BMS's are better. I paid 35k for 10KW for my first set with BMS, which at the time was a great deal, nowadays that's pretty average I think for new.

I'm overseas again working, so don't have an on the ground view of things. Going to assume they're working, as I don't have CoCT or Eskom, and the tenant in place hasn't complained. I did add another 10KWh, so it's 20KWh of storage now, so should be plenty for the tenant to abuse, even in winter. The extra 10KW is sitting on a Sunsynk, which does have native support for the BMS. Also connected to +-9KW of panels.

Sold.

Been a while, but I have revisited this, as the current driver that replaced mine didn't actually work on my Revov BMS My updated driver is here - https://github.com/csloz/dbus-serialbattery Will probably be merged back with main at some point, but this will work on the older Tianpower BMS that Revov used. I also fixed a few of the missing bits like temp sensor etc. Works fine on v3 of PI Venus.

Having run my own forums before, it is a tireless thankless task. Get some moderators and hand it over to them also Many hands make light work! Happy holidays to you and family!

Good to see more options in the market. Hopefully the BMS in this is documented, so that I don't need to write my own drivers for it TianPower /Revov looking at you...hahah

Nicely done. I should revisit some of the values on mine, see if i can map more fields to actual values.

Ok, I see that he finally updated the repo with my changes, so its "live" if you pull the current version. Fork and modify from the current repo then.

To be honest my notes in the thread, and the current code should be enough to continue working on things. Fork it, and continue. Unfortunately I just haven't had time to continue, and it works well enough for me for now. Did Louis finally update his repo with my additions? If not, you need to pull the current version from my fork here - Not that complicated You send the device a command over serial, it sends data back, thats basically it, and you parse the reply into something meaningful. Here are 2 commands I know about - command_get_version = b"\x7C\x01\x42\x00\x80\x0D" #Get version number command_get_model = b"\x7C\x01\x33\x00\xFE\x0D" #Get model number I sniffed what I could of the protocol from watching the BMS app itself, and some detective work. Current code - https://github.com/csloz/dbus-serialbattery/blob/revov/etc/dbus-serialbattery/revov.py Now we sort of know the packet format, the code needs to be reorganized, as we can parse the entire thing in one go. I put enough logging into the driver so that its useful. eg
