ATOMS3 LITE #89

Closed Marc911H closed 5 months ago

Marc911H commented 5 months ago

Hello,

I am looking to use ATOMS3 LITE which are ESP32 S3. after looking at this project https://github.com/gekkekoe/esphome-ecodan-hp/ which is made for MHI ecodan heat pump

Do you know what I need to adapt ?

I don't know about the pin

define SCK_PIN 18

define MOSI_PIN 23

define MISO_PIN 19

For the moment I have :

13:11:40 [W] [mhi_ac_ctrl:143] mhi_ac_ctrl_core.loop error: -3 13:11:40 [W] [component:237] Component took a long time for an operation (102 ms). 13:11:40 [W] [component:238] Components should block for at most 30 ms.

@Marc911H what are you trying to do? The Ecodan seems to be a whole different product line. That's not going to work with this project. You will need to compare the pinout of the connector in MHI-AC-Ctrl project with the connector pinout of the Ecodan project. The Ecodan seems to use Serial TX/RX which is totally different from SPI communication which this project uses. Even though you can probably use it, it's going to be sub-optimal and you will probably also need to convert the power/voltage.

If I were you I wouldn't even try to do this if you can't figure this out yourself as there is real potential to fry your CNI port. It's probably safer buying a pre-made variant (see MHI-AC-Ctrl repo).

Oops my mistake I jump too fast from on project to an other.
