Hello everyone,
I hope I am posting at the right place… This is my first post!
after searching for houres, and not finding any helpful posts, i would like to share my problem with the community.
I am trying to set up a custome thermostate, using a nodumcu (through ESPHome) a Nextion display and a Generic Thermostat from Home Assistant.
The plan is the following:
- display the current temperature, humidity, and target temperature to the Nextion Display
- display the current temperature, humidity, and target temperature to the thermostate card in lovelace
- “conect” the target temperature of nextion display and thermostat card, so when changing the target temperature from the display, the lovelace card is being change as well and vice versa.
So far, 1 and 2 are working fine, but I am having difficulties on number 3.
Following are the YAML files of the ESPHome and the Home Assistant configuration
ESPHome YAML:
esphome:

restore_value: no
configuration YAML: (only what is relevant)
climate:
- platform: generic_thermostat
name: Heater
heater: switch.heater
target_sensor: sensor.thermostat_temperature
min_temp: 15
So the question is, what do I have to do, in order to connect “set_temp” from the ESPHome YAML (the dispay variable) with the thermostat target temperature, so when I change, the other changes as well.
In the configuration YAML I also tryied to do this:
set_temp: '{{ ((states(''sensor.set_temperature_2'') }}'
but it does not convert to float, so no luck theire!
Any help will be much appreciate!!
Thank you in advance.
