Hi Imick and stavrosso,
have you found a solution?
If yes, Can you explained me what is the solution?
Thank you
best regards

You could give GitHub - iMicknl/ha-tahoma: Custom component for Home Assistant to interact with smart devices via Somfy TaHoma or other OverKiz based API's. a try! However, it could be that your device isn’t supported yet. In that case have a look at the open GitHub issues.
Hi Imick,
fine I have added my Hi-Kumo account to Tahoma add-on in HA.
I have this :
I how can I managed my Ac?
My AC is hitachi RAK-50RXD.
Added a issue in github : Add support for HitachiAirToAir AC RAK-50RXD. #445
thank you for your help
regards
Hello, a bit late to the party here 
Have you managed to integrate your heat pump to HA ?
I also have Yutaki Monoblock RASM with HI-BOX and Hitachi Gateway
Did you try the Overkiz integration?

Hello Kyriakos,
Yes I am using the Overkiz (by Somfy) Custom component which you can install via HACS.
It works fine , I can control the heating and the hot water by changing the temperature.
The only thing I wasn’t able to do is turn on the hot water via an automation ( if the hot water is on, on the pump wall interface I can control it without any problem , but if it is switched off I can not turn it on via home assistant, i have to physically press the power button to turn it on) .
I posted an issue for this and I hope for some help from the developers.
Please note that there is a somfy integration in the core home assistant but this does not work with the hot water entity so I use the custom component.
i hope that helps

Hi
where does the hi Kumo Module connect on the mirror box or heat pump?, i too have the same heat pump. there are no manuals
much obliged
The Hi-Box connects to the Gateway and the Gateway to the heat pump. I don’t have the connection diagram. The technician connected it during installation.
is the online interface good and easy to use?
Yes , it is good enough. Has some drawbacks but it works. You can use the application called Hi-Kumo which allows you to set the temperature of the Heating and the Hot water. Also you can set timers for both. You can not set 0.5 degrees temp changes from the app but you can from the device control panel (wall unit).
thank you!
Hi, I haven’t been active for a while. Today I discovered the incredible job you made with the Somfy/Overkiz integration, @imick. Kudos. I am going to make some tests and see if my MQTT integration is still relevant.
At first glance, it can find my AC devices and shows a temperature sensor for each (plus an inactive rssi_level sensor each), but does not present them as climate entities and they are not controlable.
You will probably need the ha-tahoma custom component for now, if you are willing to help and test we can migrate it to core as well.
If I am not mistaken, I already have an open PR.
