Haier HaierAC Tuya, HI-WA164DBI Integration

Third party integrations
1

I have an Haier MRV system with no WIFI. There is a WIFI module available HI-WA164DBI.

I cannot find any information on the web about the protocol itself but it definitely looks like there is no hON enabled on the wifi.

When i google the manual for that i can find an application on the android market for HaierAC application. but this application is part of tuya Haier AC

Is there any chance this can be added to HomeAssistant? Is the tyua part anyhow applicable or it is not relevant to the topic.

I am now in final preparation for the Haier MRV installation into the building so i need to know before i buy all of the modules.

Thanks

Hi @mazmart,
I checked some materials available on the Internet and it looks like this controller is using Modbus RTU protocol on top of RS485. I already saw it was used by some Haier heat pumps. It is a completely different protocol in comparison to what is used for home split systems so you can’t use ESPHome Haier integration. The only relevant thing I could find is this: GitHub - ktostam/HaierPi: initial
Hope it will help.
