You will need a relay module (ESP01-S+Relay) and a BS18B20 temperature probe, as well as a 4.7k resistor, cables, and a 5V power supply.

How to do it?

  1. At the very beginning, upload the Tasmota to the ESP-01S and connect to your WIFI network. It is best to immediately assign a static IP address to the device.

  2. Then you need to solder the DS18B20 sensor pins to the base as shown in colors in the photo. A-red (+3.3V), B-yellow signal, C-black ground.

  5. Configure the module

What “tape” is this?

And what “cradle”?

Hi - this appears to be for Tasmota - not ESPHome. Have you posted to the wrong forums???

That’s true. I’m new here, please forgive my novice oversight.
Nevertheless, the idea of making a thermostat from such simple elements will also be useful in this section.
