For Sale Standalone ESP32 BLE Battery Display for Victron Systems

Cheers, out of interest did you reverse engineer the BLE or did you find Victron docs?

Whats the range on the BLE in the metal confines of the van? This would be great somewhere by the door or even on the vehicle dash. I've got a newish Van conversion business and I'm looking to put some flourish into the builds. Was going down the more 'smart' route but I'm not convinced there's a market for it.

There are loads of posts across the Internet that document them, including Victron Bluetooth BLE Protocol announcement - VictronEnergy Victron Bluetooth BLE Protocol announcement - VictronEnergy

The range is generally a bit meh. The shunt is worse than the mppt in my experience, tends to be about 8 to 10 metres. I guess it probably depends on how well insulated the van is too.

So all installed and working now. Once I figured out my phone reception wasn't working once I'd connected to the monitor wifi, so I needed to go for a little drive to get better reception.
input the 2 key numbers saved and all sorted. Very easy once I worked out what was going wrong. Its working really well now

I dragged out my version I was working on something similar last year. Didn't get as far linking in electrical systems because as per usual something more pressing got in the way. I think your project has got potential because the commercial control screens are frankly massively over priced. One major brand is just a screen with a HDMI cable and USB.

Wondering if we can get the water levels off the Cerbo GX module over BLE as well. Anyway thought I'd share what I created. Great minds and all that.

Anyway here's my UI if it gives any inspiration. My plan was do this as part of a larger system, didn't think of the BLE route direct.

Hi I’m also interested in this, would it be possible to add a screen so I could see my Victron smart battery protects (iv got 3) status?
also when the screen is connected can you still use a phone to connect to the Victron device? Or does the screen need to be disconnected.
