Hi, The esp8266 talks to the hot tub via the three pin cable between the display and the main controller. This is done through a level shifter, a 74LVC1T45, this...

I soldered one onto [this breakout board](https://oshpark.com/shared_projects/8Vwts4jC) You can use any non-inverting bidirectional three state driver with direction input.

This is the [74LVC1T45GW SOT-363](https://uk.rs-online.com/web/p/buffer-converter-combinations/8168791/?relevancy-data=636F3D3126696E3D4931384E525353746F636B4E756D626572266C753D656E266D6D3D6D61746368616C6C26706D3D5E2828282872737C5253295B205D3F293F285C647B337D5B5C2D5C735D3F5C647B332C347D5B705061415D3F29297C283235285C647B387D7C5C647B317D5C2D5C647B377D2929292426706F3D3126736E3D592673723D2673743D52535F53544F434B5F4E554D4245522677633D4E4F4E45267573743D3831362D38373931267374613D3831363837393126&searchHistory=%7B%22enabled%22%3Atrue%7D) mounted to [this breakout](https://oshpark.com/shared_projects/8Vwts4jC) If anybody needs one i now have two spare breakoutboards with 74LVC1T45s mounted. It's pretty easy to solder, just tin one...

@RonandoDeLaVega Your list seems fine apart from the sot adapter, the link is for the 74lvc1t45. The switch is optional, you can just use a jumper if you have one...

Hi Edd, yeah, that'll do the job

The size of the capacitor isn't super critical, its just a local buffer for when the pumps turn on, you might get away without it - I added it at...

Yes - mine is soleley powered from the tub using the three wires going to the display controller. Try with the main branch, i've merged the new platormio code in...

Esp32 was my last choice purely because I was determined to get this running perfectly on the esp8266 but it's been plagued with problems since I started the project -...

Pretty sure the IRRemote library does its receiving/decoding from a function called in loop, works perfectly at the low message rates I have used it for - could be a...

I'll branch the current esp8266 code and make another branch for the esp32, once confirmed it's working i'll merge the esp32 code into main and leave the esp8266 for reference.
