Lay-Z-Spa Hot tub integration for esphome

hot-tub's Issues

Question on connections

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

Question on cabeling

Hi,

thanks for sharing this project.
I have problems with the initial setup.

Tub | 5V - Levelshifter 3,3V | Wemos D1 mini
Pin1 | HV -> LV | Pin 3,3V
Pin2 | GND -> GND | Pin G
Pin3 | HV1 -> LV1 | D7
Pin4 | HV2 -> LV2 | D6
Pin5 | HV3 -> LV3 | D5
Pin6 | HV4 -> LV4 | not connected

Pin Setup:
void setup() override {
pinMode(MISO, mode);
pinMode(MOSI, mode);
pinMode(SCK, mode);
pinMode(SS, mode);
}

My problem:
Power per USB, no value reading, display shows status but the buttons not working.
How can i use the 5V from HotTub for powering the ESP8266?

The level shifter is HENTEK Channel Logic Level Converter IIC I2C Modul 3,3v to 5v Bi-Directional Modul Shifter for Arduino.

Thanks
Pascal
