Balboa Spa Control Protocol

gistfile1.md

I've graduate from a gist to a full repo. See https://github.com/ccutrer/balboa_worldwide_app, especially https://github.com/ccutrer/balboa_worldwide_app/blob/master/doc/protocol.md

Hey I'm looking into controlling a Balboa spa over the same connection that the wifi module and topside panels connect to. It looks like it is an rs458 connection. I am thinking of connecting it to a raspberry pi and controlling it that way, something similar to this project: https://github.com/sfeakes/AqualinkD I'm trying to figure out the pinout of that port. Has anyone opened up their wifi module or button panel? If anyone has any info on this, I would love to know. Thanks

Have you been able to analyse a little more how the panels work? I have a VL801D that I have disassembled. Chips are etched. I can start by finding out how to power this baby, then do some serial analyser but if you have more info already, please share with me.

Hey guy! A Perfect Solution!! Worked like a charm and i translated it to php. I have just one question perhaps you know and would be great! If i want to toggle pump3 i dont know which hex to use for it. I tryed 0600 and 95 CB as Logical sequence but that is not working.

Hey swissboy22, can you send me or publish your php success? This would help me a lot. :)

@kgerlich Did you get anywhere with this? I’m about doing the same.

Any sucess ?

Wondering if anything developed on the direct wired connection bypassing the wifi module - any success?

I managed to interface a Pi directly to the controller : you need a RS-485 module and a Micro Fit ATX cable for the connection. My code and research (see README) is here : https://github.com/rsrawley/spaControl. I use Node.js as a backend server. Took me a while to figure it all out, so hopefully this helps someone out !

Thank you @rsrawley. Will look into the details of your project when I have the time.

As I just got my Spa with a Balboa BP2100G0 with a TP600 UI, I'll order the components to build a mqtt bridge with esp8266 + RS485 Transceiver.

Be prepared for me to ask questions ;-)
I'll then link my repo here.

Any update on this? I have mine down right now to replace motor, so very interested in getting it added to my Home Assistant.

Yep, working really fine ;-)

Hi swissboy - would you mind sharing your php solution?

This is great. Im having a little trouble understanding the messaging format. My goal is to (using the wifi module) use a macro on my watch to toggle the pumps so I do not have to use my phone. the main control panel on my tub no longer works and I really just need to have a way to turn the pumps on while im in the tub. If someone could give me an example hex string that would tell the pump2 to turn on, that would be great. or is the crc thing critical to that? Thanks in advance.

It's 0x05 for toggle item as described here: https://github.com/ccutrer/balboa_worldwide_app/blob/main/doc/protocol.md#toggle-item You need to wrap this in StartOfFrame and EndOfFrame. CRC is important and your ID needs to be registered.
