I wish to install a device in my fuse box that can monitor the energy consumption of each fuse on individual basis. I havn’t found any Homey compatible devices able to do this(?).

However, I came across IoTaWatt, an open source project that seem to do exactly what I am looking for. [https://iotawatt.com/](https://iotawatt.com/)

Any experience with this? Would it be possible to get a Homey app developer for this device?

Looks nice. A local alternative to Emporia which has only a inofficial cloud API.  
But this product seems to have a local storage and a webserver to display the data. But no webservice or API to read real time data from Homey.

Thanks, just looked at the first page.  
So read historical data grouped by minute or seconds (5sec min?) could be possible to update a homey device in that interval.

Emporia also looks like a good alternative. Doesn’t seem to have a Homey app either though.

From what I have found the only alternatives for Homey are Shelly and Aeotec(?), but they only support like max 4 circuits.
