Configure OH for heating control.(need help)

Setup, Configuration and Use Beginners
1

Good morning:
I am currently using the cayenne platform, but I have problems with frequent disconnections with the server.
I need help to install heating control system at home with OH.
I have the following hardware:
2 raspberry pi zero w
1 temperature probe ds18b20
2 relay modules of 2 relays.
Approach:
1.- A raspberry pi zero w together with the ds18b20 probe use it as a thermostat placed in the room.
2.- The second raspberry together with the 2 relay modules to activate / deactivate the heating.
Operating mode:
1.- In the morning: if the temperature of the room is lower than 16.5 degrees, activate the heating and deactivate it if it exceeds 17.5 degrees. And this within a schedule between 10 in the morning and 16 in the afternoon.
2.- In the afternoon: if the temperature of the room is lower than 18.5 degrees, activate the heating and deactivate it if it exceeds 21 degrees. And this within a schedule between 4 pm and 10:30 pm at night.
Thank you very much in advance.

Using a RaspiZeroW as a thermostat is overkill.
Use a devboard ESP like the wemos mini and upload tasmota on it

Install openhabian and mosquitto on the Rasperry pi

https://docs.openhab.org/installation/openhabian.html

https://docs.openhab.org/installation/openhabian.html#optional-components

Install the mqtt binding and the GPIO binding on openHAB

https://docs.openhab.org/addons/bindings/mqtt1/readme.html

https://docs.openhab.org/addons/bindings/gpio1/readme.html

Set up one item to receive the temp from the wemos
and 2 items to trigger your relays
And one rule to Trigger the relays when the temperature changes

Good luck

Thanks, but I have 2 pi0W…

Then you need to set up 1 piow with your ds18b20

and publish the values over mqtt with python

but I have problems to start the pi0w via wifi, I configure openhabian.conf
…
wifi_ssid=“usg555”
or
wifi_ssid=usg555
I put both modes and I can not get the pi0w to start…

Start over
Format your sd card and burn the latest pi image
then
