Shelly 20210 EM Schalt-Messaktor Wi-Fi

Product Information

Earlier this month, we added a Sonoff POW R2 smart switch with power monitoring to our washing machine to enable power logging in Home Assistant and to add notifications when a wash has finished. After researching other alternatives, I found the Shelly EM,a very compact device with one or two CT sensors. The CT sensors clip around the mains power wire and don't require the circuit to be broken or modified to use. Installation These sensors are based on code on community.home-assistant.io/t/configuring-shelly-em-energy-meter. Observe the recorded history of the Shelly Device events. See the date, time and type of action executed such as the Device being switched On/Off. Timer

If the BUTTON TYPE of the switch connected to the device is set to momentary or detached switch, the integration creates an event entity for this switch. You can use this entity in your automations. Event entities (generation 2) I added new Utility Meters into my main configuration to keep long-term stats for each sensor.yaml file as follows: utility_meter: Generation 1 “Shelly 4Pro” and “Shelly Sense” are not supported (devices based on old CoAP v1 protocol)Shelly Pro EM-50 can be accessed, set up, and monitored remotely by the User, as well as the Device can access and communicate with an automation system, as long as they are in the same network infrastructure.

Observe the Shelly Device total power in Watts (W), overall consumption in kilo-watt-hours (kWh), voltage in Volts (V), current in Amps (A), and power factor (PF). Below these measurements, observe a consumption chart, in Watt-hours (Wh), of the Shelly Device in the last 24 hours. The integration uses the following strategy to name its entities if the device has more than one relay:If Shelly devices are in a different subnet than the Home Assistant server, you should ensure communication on UDP port 5683 between these subnets.
