Hi there, I’m thinking about buying a Tesla Wall Connector but this doesn’t has an API to connect with Homey and doesn’t have power metering (AFAIK). I need to measure the total power on this charger so adding a DIN rail module on the fuse (32A) of the charger should do the trick. Would be great if…

The charger will be single phase unfortunately…

Shelly EM. Not for DIN rail but some DIN adapters might be available.

Looks interesting indeed! Do you have one? Is it possible to view for example the total used energy in 2020 (in insights?)?

They also have a one-clamp version => https://www.amazon.co.uk/Aeotec-Energy-Electricity-Monitor-Consumption/dp/B017DV3URS Or you can buy a (much cheaper) clamp and add it to your own hardware. Zappi for example sells a clamp for just under 20 euro: CT klem 5 meter - Myenergi BV (note: this require…

Great info! I’ll look into this, thanks :slight_smile:

I have the Shelly 3EM the three phase version of the same equipment. One can see the power and cumulative energy in the insights. In Shelly android or ios app you can get more details based on hour, day, month and year

I have a “dumb” EV 3 phase charger. How can the Shelly 3EM be set up to see the energy going through the charger? And can I use a Shelly 1 to turn the charger on/off through the pilot cable?

A clamp would do the trick. Aeotec makes a z-wave clamp, check out Aeotec Home Energy Meter Gen5 - 3 clamp
