For those wondering _why_ this device is there, it seems it gave points under the Code for Sustainable Homes https://en.wikipedia.org/wiki/Code_for_Sustainable_Homes https://en.wikipedia.org/wiki/Code_for_Sustainable_Homes so the apartment could have a better environmental rating, as mentioned at https://uk-metering.net/products/netthings-energy-manager https://uk-metering.net/products/netthings-energy-manager Seems that making sure the device actually works and is accurate was not a requirement however...
