Many problem with Overkiz integration (hikumo)

The problem

Hi,

There are several integration problems with hikumo (hitachi overkiz box AHP-SMB-01).
My hardware is a "Triple C RAM-90NP5E" (with 1 water-heater Yutampo (with ATW-HCD-01 module) and 4 air split (with ATW-TAG-02 module).

*1st:
If I try to change the temperature (in airsplit) or start ventilation only, an error message appears:
"Échec de l'appel du service climate/set_temperature. core:DHWTemperatureState is not a float" (yep, it's the french version)

*2nd : “Modbus” consumption indications are abnormal
No data ==> MODBUS (15400226/1#10) Electric energy consumption ----- sensor.none_modbus_15400226_1_10_electric_energy_consumption
—
inconsistent data ==> MODBUS (15400226/1#10) Electric power consumption ----- sensor.none_modbus_15400226_1_10_electric_power_consumption

*3nd :Water-heater Yutampo data is totaly missing.

Hi
Same problem here. I have an hitachi heat pump, i have only power and consumption modbus shown. No way to start or stop the pump

Having only these sensors available, and not a climate entity, means that your device is not supported yet in the Overkiz integration.

@strati64 when looking in Home Assistant, how does your device info look? Can you add a screenshot here.
Example:

@sdudulon2 please have a look at the open issues and see if your device is already present. Otherwise, create a new issue and add your diagnostics and information above. There are many different devices from Hitachi, so good to keep it separated first, until we figure out the exact device.

@sdudulon2 please

It's a Hikumo overkiz box (Hi Box) :

I have a "good news". I retested and some problems (1st) are "partially resolved" probably by updating to version "2024.5.5" (since 2024.5.1 last month)

*2nd & *3nd: Same problem of 98939 but not the same hardware : Yutampo (it's the same apps & overkiz hikumo integration) !
(Hitachi Yutaki = Air-to-Water Heat Pumps (system full water) + hot water tank; yutampo = Only hot water tank ! )

*1st: The same message always appears "Échec de l'appel du service climate/set_temperature. core:DHWTemperatureState is not a float" (in french... Calling service failed !)
--> But actually i can switches to ventilation/air conditioning/heating mode, adjusts the fan speed or the temperature "correctly".

On the other hand, we must leave "a delay" if we want to modify several parameters (activate air conditioning... sleep 10s... adjust temperature... sleep 10s... adjust fan speed... sleep 10s... etc) . If you modify several parameters too quickly, the Hikumo system ignores the command until the previous one is "finished".

It would be necessary to be able to send several parameters "in a single command" (adjust fan speed + temperature + mode THEN validate) to resolve this bug like the hikumo application does which sends a single command and not 3.
