Product Description Control a wide range of home appliances and office equipment (lights, power lines, garage doors, curtains, security systems, heating, air conditioners, etc.) from anywhere. The UL-certified Shelly 1PM can control one electrical circuit of lights or appliances up to 16A remotely. Connect 110-240v AC or 24-60v DC and measure the power consumption of any appliance. Power metering Shelly 1PM has two integrated precise power meters that allow you to measure the consumption for each channel separately. Based on your monthly limit, it can execute different actions. Overconsumption and overheating protection Shelly 1PM has а built-in temperature sensor for overheating protection. If the PCB temperature goes above a danger level, the device will turn off. In case you want to control your consumption and spending, set your preferred daily/monthly energy use, and Shelly 2.5 will turn off the circuit immediately if it detects a higher value. Wide range of voltage support Shelly 1PM supports up to 110-240v AC or 24-60v DC, making it suitable for most types of Smart Home projects! Additionally, Shelly 1PM has an optional add-on for temperature, humidity, reed switch and other sensors. Hook your lights, washing machine, dryer, refrigerator, or any other old appliance that you want to control and measure remotely.
