I have set up an ESP32-based device to control the boiler through a template switch in ESPHome. The status of this switch is correctly passed to Home Assistant. When I change the status in Home Assistant, it also updates on the ESPHome device’s screen. However, when I press the Select button on the ESPHome device, the logs show that an attempt to change the boiler’s state (ON/OFF) was made, but the physical boiler does not switch. There are also no changes in Home Assistant or on the ESPHome device’s screen. What am I doing wrong? Any advice?
