From the review provided, it seems that this ESP thermostat device is a simple and versatile solution for the user's application, allowing for customization such as injecting a separate switching source if desired. The user mentioned running 3V through the signal side and 24VAC through the switch side, with a current under 3 amps. However, they observed that the device kept resetting, causing the connected ESP32 controller to reboot, which was experienced across multiple units. The user was using the device to create a thermostat compatible with Home Assistant. It is important to note that the lack of documentation and unmarked jumpers on the board presented challenges for the user, necessitating a reverse-engineering approach to understand and potentially troubleshoot the device fully. **
