The digital meter of the solar installation only sends updates twice a day to a portal of the installer. Never attach a clamp on an energized wire while it’s not connected to the Shelly! 4. Attach wires ¶ My house has 3-phase electricity (3x400V+N) with an analog meter and a photovoltaic (PV/solar) installation with a digital meter.

The Youtube vid covers general concepts, and below I’ve listed the basic steps to getting this working, plus posted some code samples you can use. You can enable MQTT or set CoIoT unicast to the IP of your Home Assistant instance. Integrating Shelly 3EM in Home Assistant ¶For instantaneous power reading, yes, all will show fairly accurate values. The flag I raised is related to the sampling rate of the devices and using these values to calculate power usage over time. Basic Kilowatt Hours. The point of my picture was to show the possible answers to the question, ‘What did that pot of coffee cost to make?’. As you can see most of the power hungry home appliances we use, use simple power on and off cycling to control things like temperature, cooking power, refrigeration level… This leads to very ‘spikey’ square wave power usages. If a device cycles power several times per minute and the power monitoring device only samples a couple samples per minute, the ‘area under the curve’ is going too often be very inaccurate. Don’t worry, eventually you’ll see your data appear here, give it some time. There is no data to show. It can take up to 2 hours for new data to arrive after you configure your energy dashboard. After a few hours, data will start to appear Samsung SmarThings setup/system/hub, I have found to be the most comprehensive, but it is still not 100%. For example, it has been a while, but I do not think they support Hue. But they support CentraLite, Ikea, OSRAM among others.

Can this database be updated, good news YES. You can request the developers to queue up a change. Or if you are adept, you can write your own ‘handler’ for the device. A key feature of energy monitors is the way they convert raw data into meaningful info. The normal way of reading energy data is through kilowatt-hours (kWh) and hard money! It might take a few minutes for data to start coming through but you should start to see the energy dashboard populating with your current usage: Standing Charges Import the JSON dashboard from below. You will need to go through each panel and change the query. If you have set up Grafana from scratch then you’ll need to ensure InfluxDB has been set up within Grafana, it’s quite easy to do.

Product Questions & Answers

This was the orignal solution I personally acquired for doing per-circuit monitoring in my house. After getting everything setup initially, It was working fine.

The Shelly Home Automation portfolio includes a variety of relay switches, sensors, plugs, bulbs, and other controllers, all connected and controlled through your Wi-Fi network. The new Shelly Plus and Shelly Pro lines of products additionally support Bluetooth connectivity for faster and more stable device communication, and the new Shelly Pro line offers LAN and Wi-Fi usage simultaneously. The entire Shelly portfolio is available at https://shelly.cloud/ The Shelly EM is an energy monitoring device which can use a current clamp to monitor the amount of energy being drawn from the power feed that the Shelly is monitoring.

BlitzWolf BW-SHP13 (OEM version of Tuya TS0121) → https://github.com/zigpy/zha-device-handlers/issues/605 Install the antenna and then connect the power cable and the antenna to the device. Clamp sensors around service mains, and connect the power wires from a 2-pole circuit breaker to the smart monitor. Install the Sense App, connect it to your WiFi connection, and create and configure your account. You are done!
