I want to measure the consumption of my Air Conditioning Units (including compressors) which are directly wired in and there is no plug I can put a wall plug to. They are connected into my Switchboard and I was wondering if someone can help me with what device I need to to measure from the Switchboard. I am going to get an electrician to do the installation, but like to know what device it is I need
The easiest way would probably be to replace the module with a smart switch with power metering included.
The module is probably installed on a DIN rail, so make a search for “smart switch power metering din rail” followed by your choice of communication protocol.
You have several options for communication, like wireless ones: Wifi, Zigbee, Z-wave or wired ones: RS485, KNX, and probably more.
Thanks, appreciate the response. I have looked at the Shelly Pro 4PM as the Shelly devices seem to get good reviews, do you see any reason why this one wouldn’t work ?
- 4 outputs, 16A each. Total device maximum of 40A
Your fuses are rated 20A each 
As you only want to measure consumption and not switch it you can make use of some cheap non-contact energy meter 
For example two of these pzem004t modules paired with a esp and esphome should enable your power measuring on two circuits up to 100A for less than $30 
That would be illegal in my country. You have to put the power metering device behind the module.
