Shelly Uni works on 12 to 36 VDC, making it perfect for the automation of your camper and its appliances! Use the analog input to measure your camper batteries and receive an instant notification to your phone if they're running low. Together with other Shelly devices, you can turn off connected appliances to take further action and save power. Additionally, you can use its binary inputs to detect if a door has been opened and be alerted of a potential break-in while you're away.
