This is not our new development, but we somehow forget to tell our customers about it. Very often at facilities there is a need to monitor how exactly the equipment works on the power supply, how often the power is lost on this or that type of equipment. This is where our power sensor army comes to the rescue. This is a very simple but useful sensor. By the way, our cloud monitoring service displays data from this sensor every minute, and the telegram bot notifies when the power goes out and is restored.
