Configuration

Hi, do you know if there has been any update to the Hitachi API? I still haven’t been able to get this integration to work.

Hello, I have problem with the Hitachi API.
I am using the svmironov aircloud script.
It runs without errors, but with no action on my 155_RAD_50RPE Hitachi climatization
I have this console message " {“time”:“2024-10-03T16:45:35.714”,“code”:“PCF009”,“message”:“Thing is offline, try after sometime”,“details”:“uri=/basic-idu-control/general-control-command/30173”} "

Do you know what’s happen ?

I came across this info on the ATW-IOT-01 Hitachi H-Link gateway that may offer some potential integration opportunities for those with a “dumb” Hitachi HVAC system that uses the twin-wire H-Link connection to link together the outdoor and indoor units with a wall mounted controller:

Another post offers some further insights:

Sorry, it’s a late reply but I needed to only install @svmironov add-on from HACS.
At the moment (february 2025), in my installation (Dockerized HA) I can control the two internal units of my HVAC system without any issue.

Hello,

I have Hitachi VRF device and I use Hitachi Aircloud Pro app.
Do you think that it is possible to use that integration?

Thank you in advance for your answer.

Hi guys! For those interested, I’ve built a relatively simple ESPHome-driven dongle for my Hitachi RAK-25PEC AC. It’s based on Florian’s hackaday project and communicates via the H-Link serial protocol.

This dongle serves as a replacement for the SPX-WFGXX cloud adapter, meaning it could potentially work with any AC unit that supports H-Link connectivity.
