Hello and welcome aboard, Paul. If you haven’t already read it, have a look at this thread: > [@DIY Current Monitor on Raspberry Pi. My power calculation isn't accurate. Help please?](https://community.openenergymonitor.org/t/diy-current-monitor-on-raspberry-pi-my-power-calculation-isnt-accurate-help-please/13266/174): > > The two 100 mA c.t’s should read 110 A max, the 50 mA one 104.75 A (both with a little bit to spare). Now you can see where the money goes… --- _[View the full topic](https://community.openenergymonitor.org/t/help-monitoring-2-phases-of-ac-current-only-ads1115-nodemcu/24475)._
