22.6 V DC to power Shelly 1 with Temperature Add-On

  • I am using a shelly 1 with the shelly temperature add-on powered by 24V AC converted to DC using a rectifier with the bridge on 24V-60V DC setting.

    My setup is the same as this and I am using it for the same purpose, to control a 2 wire (24 V AC) thermostat.

    However, I am only getting 22.6V DC after conversion. I am using one DS18B20 and I measure 4.2 V on the sensor power wires.

    The relay works fine but the temperature sensor is not showing. It worked fine when I tested it with a different 12V DC source.

    Can I use the shelly 1 with 22.6V DC with jumper on the 12V setting? Could this solve the problem?

  • I changed nothing and I powered the device off and on again and now the temperature is showing up fine. I will mark this as resolved.
