I’m upgrading my service at home from a 100A 20 circuit panel to a 200A 40/80 circuit panel (US), so this is the time for me to add some monitoring. I’ve got a few questions before I make the purchase.
With the 14 circuit limit on the IoTaWatt, is it possible to slave a 2nd unit for future expansion? As it is, I’ll be running both the double range and oven 230v circuits through one CT to save inputs. It’d be nice to have one for each branch receptacle circuit too.
What’s the advantage of combining multiple circuits using a headphone splitter instead of running them through the CT? Is it when not enough room (or physically unable)? Or accuracy? I’ll miss out on some branch circuits that I figured would get derived from subtracting the difference between mains and all the rest of the CT’s.
With the panel apart, is the SplitCore 200A CT ( ECS24200)more accurate than the clamp-on? I’d do a solid core if I had the option…
And the loaded question - What’s the advantage of the emonTx vs IoTaWatt? Seems emonTx can slave multiple units, and there is temperature/pulse input. Cost would be slightly more at 4 inputs per unit… I’d really like an ethernet option instead of WiFi (would go right to a business class switch instead of my consumer grade WiFi, and no worries about someone hacking in via Ethernet). IoTaWatt has more inputs and seems like a cleaner package, and I’d probably start with one to see how it goes…
Thanks guys, I’m excited to do this! Hope to learn more coding and play with the data at some point too…
