openspa's Issues

Question

Hi @NickB1,

Sorry for opening this as an issue, it's more of a question, and I hope you don't mind me asking here. I'm following your OpenSpa and also the balboa-spa-mqtt-controller projects trying to do something similar. My controller is (still) working but is a decade old. If it fails, I'll try do implement a solution similar to OpenSpa, but meanwhile I would like to connect my spa to get status and control if with an ESP8266.

My spa is a Balboa HSEX2000 Mach3 (part no 54503-01) and is branded GL2000 inside a plastic enclosure (know there is a different variant of the same with metallic enclosure). Display is ML400.

Would you mind me asking which display is connected to yours? And do you know the type of controller that was originally fit to it? I see you mentioned 25501 on hackaday.io, would you mind sharing some more details?

I was initially trying to use the information found here, but found out my spa has a 8-pin Molex connector to the display and not 4-pin as is the case for the referenced project which is RS485 based. See particularly this issue if you're interested. Although yours is a RJ45, I was hoping it would be similar to mine, just different connector.

Anything you could share that could help me shed some light on my issue? Protocol? Connections?

Thanks in advance.
