interesting thanks for explaining that. Can I ask you to post your config please?
I have a separate sensor in the room and want it displayed in Celsius which I have added to the code but not sure if its even remotely correct.
sensor.garage_aq_temperature
Sure, i have a tiny bit more complicated setup, though: i added a switch which allows me to choose from HA either internal or external sensor to be used. So first you must create this switch:
switch:
- platform: template
name: "Used extrenal sensor in garage"
id: external_sensor_garage
optimistic: true
restore_mode: RESTORE_DEFAULT_ON
Then you import your temperature sensor into esphome and configure so it will send temperature reading into climate:
- platform: homeassistant
name: "Garage temperature"
id: garage_temperature
internal: true
device_class: temperature
unit_of_measurement: "°C"
entity_id: sensor.garage_aq_temperature
on_value:
then:
- if:
condition:
- switch.is_on:
id: external_sensor_garage
then:
- lambda: |-
if(id(garage_temperature).has_state()) {
id(climate_garage).set_remote_temperature(x);
ESP_LOGW("temperature", "using XIAOMI sensor %.2f", x);
} else {
id(climate_garage).set_remote_temperature(0);
ESP_LOGW("temperature", "using internal sensor, external not available");
}
else:
- lambda: |-
id(climate_garage).set_remote_temperature(0);
ESP_LOGW("temperature", "using internal sensor");
It’s a good idea to add “remote_temperature_timeout: 30min” to your climate section. This will ensure that internal sensor will be used after 30 minutes if external is unavailable.

Wow thanks for that but I am having trouble understanding it. So I cracked open the Mitsu after flashing the previous config. I have this installed it
So the Mitsu shows 22.5 deg currently in the above pic while the external sensor I added had this in developer tools.
So is this the Mitsu showing me its internal temp sensor?
I definitely added it in the config as you can see per my previous post and I dont see it anywhere. Can you see any issues with my previous post? Asking as not sure what the Mitsu did with that one…
Also if I add your code I assume I can see this switch in the config but is this what the Mitsu will use as the target naturally?
You can temporarily set “internal: false” for your homeassistant sensor, so you’ll see if temperautre value will show up (it should show same value as your external temperature sensor). If it does, then climate should use external temperature, which is set with lambda command “id(climate_garage).set_remote_temperature(x);”. If you want to go back to internal just send zero value with this command: “id(climate_garage).set_remote_temperature(0)”.
Note that this command is only executed when temperature sensor changes value, so it may take time.
Since there are two options for using remote temperature (one is explained above, other one is to use services via HA) perhaps you read original Geoff Davis’s page, where it’s a bit better explained: https://github.com/geoffdavis/esphome-mitsubishiheatpump
search under “Remote temperature”.
Hmm I think I understand what you are saying but unsure where everything is meant to be shown.
For eg this is my current state

So couple of questions
Does it reflect the sensor it is relying on in the climate control?
The 20°C is that the internal temp?
The 15°C outside air temp what is that?
The 22.5°C seems to be sensor.garage_aq_temperature?
Also how do I know which one its taking into account currently if I assume its showing the internal one?
thanks
Your error is here:
on_value:
then:
- lambda: |-
id(hp).set_remote_temperature(0);
id(hp).set_remote_temperature(0) means command to use internal sensor. For external one you must enter
on_value:
then:
- lambda: |-
id(hp).set_remote_temperature(x);
note that X instead of zero, which means that you’re sending external temperature value. Entering zero means going back to internal - this is what you’re doing right now.
When current temperature of climate will show the same as your external sensor then you’ll know that climate is using external sensor. Note that it can take time for external temperature to show in HA, since “on_value” part is only executed when temperature in external sensor changes. So, quick test would be to warm it with your hand to force temperature change.
If external sensor will be unavailable for 30 minutes (set by “remote_temperature_timeout” variable) system will automatically go to internal one. I modified that part in my example so system goes to internal immediately when/if sensor is offline (second if—then part of my example - if(id(garage_temperature)…)
Thanks.
I added this now, hope its correct. Wasn’t sure what the %.2f was however
on_value:
then:
# - lambda: |-
# id(hp).set_remote_temperature(0);
- if:
condition:
- switch.is_on:
id: external_sensor_garage
then:
- lambda: |-
if(id(current_temp).has_state()) {
id(hp).set_remote_temperature(x);
ESP_LOGW("temperature", "using Aq sensor %.2f", x);
} else {
id(hp).set_remote_temperature(0);
ESP_LOGW("temperature", "using internal sensor, external not available");
}
else:
- lambda: |-
id(hp).set_remote_temperature(0);
ESP_LOGW("temperature", "using internal sensor");
temperature resolution (2 decimals). You could change to %.1f (1 decimal). I’m not sure why i left to 2 digits; leftover from testing, i guess… it doesn’t harm, though.
