The Shelly EM has a seven-way screw terminal input for the mains live and neutral, a relay output and two inputs for the CT sensors. The device can either be connected to the Shelly Cloud service or via MQTT to a local server to record the data for each channel. value_template: "{{ ((states('sensor.shelly_loft_ovenandpump_apparent_power')|float) / (states('sensor.shelly_loft_ovenandpump_line_voltage')|float))|round(2) }}" The Device reports accumulated energy as well as instantaneous voltage, current, active, and apparent power per phase in real time. It stores data in non-volatile memory that can be retrieved for a period of up to 60 days in 1-minute intervals. If the Input Mode of the switch connected to the device is set to Button, the integration creates an event entity for this switch. You can use this entity in your automations. Events

The integration uses the following strategy to name its entities if the device has more than one relay: With most of the main household appliances and computers being monitored in Home Assistant, this only left our loft workshop without any energy monitoring. To add the new sensors to the new Energy Dashboard, you need to create template sensors with the name starting with "energy". Each template sensor also requires additional attribute templates: attribute_templates:Shelly generation 2 devices running firmware 0.12 or later can act as a Bluetooth proxy for advertisements. Active or passive listening can be enabled in the options flow. Options If you can’t find the CoIoT peer settings in the device’s web panel, it’s probably using an ancient firmware version, and you should update it to the current one. CAUTION! Plug in or unplug the LAN cable only when the Device is powered off! The LAN cable connector must not be metallic in the parts touched by the user to plug in or unplug the cable. Addon interface In case device name and channel names are not set, the entity name will be generated by the Device Type, Device ID and Channel Number. If Shelly devices are in a different subnet than the Home Assistant server, you should ensure communication on UDP port 5683 between these subnets.

Shelly EM

On the Home Assistant user interface, I added a new tab for the loft power sensors and added each sensor with the following code: type: entities If Device Name or Channel Name is set in the device, the integration will use them to generate the entities’ name. These sensors are based on code on community.home-assistant.io/t/configuring-shelly-em-energy-meter.

Observe a chart with the Shelly Device maximum and minimum voltage displayed in Volts (V). Above the voltage chart, you can select the time interval and the date from which you want data to be shown. Auto off: After turning on, the relay output will be automatically turned off after a predefined time (in seconds).

value_template: "{{ ((states('sensor.shelly_loft_workbench_apparent_power')|float) / (states('sensor.shelly_loft_workbench_line_voltage')|float))|round(2) }}" The integration offers device services which can be triggered by a configuration button. OTA firmware update If only the device name is set, and the device has multiple channels, the channel number will be appended to the entity name (e.g., Channel 2). If Home Assistant is running as a virtual machine or service on an operating system other than Home Assistant OS, you should open UDP port 5683 on the device’s firewall and/or ensure that communication from this port is redirected to the Home Assistant service. If you think your Shelly devices are working correctly and don’t want to change your network/configuration, you can ignore the repair issue. Still, you must know you are giving up the best experience of using first-generation Shelly devices with Home Assistant.We have a small fuse box with two RCBO (Residual Current Breaker with Over-Current) breakers which power the reflow oven and solar thermal pump on one RCBO and the workbench, air compressor and computers on the second RCBO. 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 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 If Channel Name is set to the default value, the integration will use the Device ID and default channel name to generate the entities’ name, e.g. ShellyPro4PM-9808D1D8B912 switch_0.
