Shelly 20210 EM Schalt-Messaktor Wi-Fi

Product Information

Disclaimer: Before I continue, remember that working with electricity is dangerous, and it can kill. This blog post is designed to illustrate the capabilities of the Shelly EM – it is not an installation guide. Follow the official Shelly instructions and use a qualified electrician. So what does this mean? It means that if you want an ‘open’ Zigbee setup/system/hub, you are still probably going to have to buy the device vendors hub just to make sure you have the latest firmware on all of your devices and be ready in case an update comes out.

Great sleuthing. They’re almost certainly the calibration constants… you can tell because each set of 3 is so similar and yet slightly different. Each one will be compensating for component variation on that channel. I’m not sure those numbers will be much assistance for your single channel unit, but you’re now well positioned to reflash your EM3 and then use those numbers to program up all the various gains. These wires are then ran to 3 different fuses (marked orange below) which each are on a different phase. The Square D edition of the Sense smartphone app is used to monitor the Wiser Smart Energy Monitor system. It is an easy to use app with almost all the essential features to monitor and evaluate which devices are making problems for you in your electricity bill.

At the top end of the spectrum is device monitoring by reading energy signatures flowing throw the main pipe. As you can see from the above photo, I'm using a single current clamp to monitor the incoming live feed. Our meter tails are not coloured, so figuring out which was the right feed to monitor and which way round to place the current clamp took some trial and error. However, once I got positive (rather than negative) readings within the app, I knew the device was installed just how I needed it. A best smart home energy monitor can also prevent costly repairs by sending updates when critical systems, such as a sump pump, stop running.

Need two inputs and outputs? The Shelly 2.5, like the Shelly 1PM, also has power monitoring. But, the 2.5 has two inputs, and two outputs. Develco Norwegian HAN Adapter (Develco EMIZB-132) → https://github.com/zigpy/zha-device-handlers/issues/267 A lot of energy monitor products on the market require using their specific apps to access info. Some like Sense are compatible with IFTTT while others, like Aeotec, are controlled through a generic z-wave smart home gateway. Should I buy a Smart Home Energy Monitor?Zigbee2MQTT, what looks like a good infrastructure in place. Some vendors, but far from as deep as SmarThings. At the time I'm writing this post, there is an open feature request for supporting a standing charge – Energy: Add fixed daily cost. In the UK, it's fairly common to have a unit rate (price per kWh), and a standing charge (a fixed daily cost). Overall- I am against any product which relies on a vendor's servers to function. I am a very strong proponent of full, local control. As such, unless you plan on flashing this device to ESP Home using the links provided- I would recommend another product. However- if you do flash to Esp home, the price / functionality is unbeatable by anything else on this list. A bit pricy, IMO based on the alternatives here, however, it does offer din-rail mounting, which can make for a very clean setup if you have a seperate nearby box with din-rails.

Each setup/system/hub maintains a database of ‘capabilities’ for every device that is supported by this setup/system/hub. Is there a ‘standard’ for these records? Of course NOT. Are the records different between setup/system/hub? YEP! Home Assistant has supported energy management since 2021.8 of Home Assistant Core, so I'm interested to see how easily the Shelly EM will integrate with my existing Home Assistant setup. The Shelly EM value_template: "{{ ((states('sensor.weekly_energy_peak') | float * 0.2325) + (states('sensor.weekly_energy_offpeak') | float) * 0.1278 ) | round(2) }}" Buy your Shelly EM with one or two current clamp sensors. Shelly make a 50A and a 120A sensor for the same price. The difference between these should be very obvious, in which case why would you buy the 50A version? I don’t know. The only other difference is the size, the 120A is a bit bigger. I bought both, to compare / contrast and for flexibility.

If you do not wish to be dependant on the vendor's cloud, which without notice, can stop working- A reddit user has created a guide on how to flash this device to leverage ESP Home, for full local control.
