Connect to Daly BMS via TTL/UART #225

Why not allow direct connection via TTL to your PI3/4 device ? It is possible and you can read data directly from Daly BMS. No need for wireless.

This is not part of this project.

Some users don't have the Pi near their BMS and in my case, I have 12BMS plus another 10 in mobile 12V batteries which I need to monitor. Cabling impossible.

OGG, I just watched your video. Most of us don't have 22 BMS to monitor and as you found, Bluetooth just isn't reliable enough. I'm still looking for a good solution that can look at several BMS through RS485/TTL/CAN. for more reliable monitoring that doesn't require a MCU for each BMS. I currently run the standalone program, HybridInverterMon, which can monitor 1 JKBMS over RS485 (Im working on adding additional JKBMS but I'm not familiar with C# or DOTNET) and not any other brand BMS. If this project can be expanded to include RS485 communication it sounds good for even up to 10 BMS. I also don't know why peterboards require 1 board per BMS because I thought CAN also supports multi devices on a bus. You of course have your batteries all over the garage for testing and what not so cabling would be a mess but for someone like me who only plan on a few batteries in the same space, this would be ideal.
