Hi,

First, off fantastic work, i got my hot tub last week and wanted to use esphome with HASSIO to monitor and control, you have saved me a lot of work. i found that my unit is the 6 wire version.

SPI isn't something that I have used much before, are you using a pre-made level shifter like: SN74LVC1T45DBVR?

Cheers tom

My efforts on the 6 pin version are on hold at the moment while I sort out other stuff :( Haven't got passed just probing it. Haven't thought about how to emulate the control panel yet, as it will only transmit synchronously on the master clock. I suppose disconnect chip select, and transmit in its place.
