HomeKit for Sensibo Air - It is possible ?

[mateusmsantin]

Hi Guys, there is possible to make a control with ESP8266 ? I don’t find a exemple to beging tests. I would like to do something like this https://support.sensibo.com/l/en/article/yt2lig7u5z-home-kit-for-sensibo-air

I would appreciate any kind of help. Thx.

Could it be this?

[mateusmsantin]

Sounds good, I will try to do it. Thanks...

I don't quite understand the problem, can you describe it in more detail. Maybe this will help: https://nrchkb.github.io/wiki/service/thermostat/

The serial log show me:

This is a problem due to memory. Make sure you are using the correct Homekit library. Check the recommended IDE settings.

[mateusmsantin]

I had configure IDE like your remomendadion, there was some configuration diferente before.

But the error is the same:

`>>> [ 43163] HomeKit: [Client 1073684196] Pair Verify Step 1/2

The getter and setter I thing is out of range, or wrong. I read that currente temperatura is out of range, the pairing don't works. I fixed for teste to 23.0, but I don't know how I set the other parametres.

homekit_characteristic_t ac_current_state = HOMEKITCHARACTERISTIC(CURRENT_HEATING_COOLING_STATE, 0); homekit_characteristic_t ac_target_state = HOMEKITCHARACTERISTIC(TARGET_HEATING_COOLING_STATE, 0); homekit_characteristic_t ac_target_temp = HOMEKITCHARACTERISTIC(TARGET_TEMPERATURE, 0); homekit_characteristic_t ac_display_units = HOMEKITCHARACTERISTIC(TEMPERATURE_DISPLAY_UNITS, 0);

CURRENT STATE GETTER CALLED! RESPONDING WITH: 0 TARGET STATE GETTER CALLED! RESPONDING WITH: 0 TARGET TEMP GETTER CALLED! RESPONDING WITH: 0.000000

[densh1k]

Limits:

CURRENT_HEATING_COOLING_STATE: 0, 1, 2 TARGET_HEATING_COOLING_STATE: 0, 1, 2, 3 TARGET_TEMPERATURE: 10...38 TEMPERATURE_DISPLAY_UNITS: 0, 1

Try this with your own parameters: void my_homekit_setup() { ac_current_state.value.float_value = 1; }

[mateusmsantin]

Hi densh1k, you found the problem. I changed my code to:

`//ac_active.setter = active_setter; //ac_current_state.getter = current_state_getter; //ac_current_state.setter = current_state_setter;

ac_current_state.value.float_value = 1;

//ac_target_state.setter = target_state_setter; //ac_target_state.getter = target_state_getter; ac_target_state.value.float_value = 30;

//ac_target_temp.setter = target_temp_setter; //ac_target_temp.getter = target_temp_getter; ac_target_temp.value.float_value = 19;`

I fixed, and now, I can pairing the device.

Thx!
