Understood on the CTs, I trusted your word on it, was just curious how it worked for my own knowledge. Also yes I read your documentation already and am aware of the need to pass the wires through opposite directions.
At the end of the day I really just want to know what my “luxury” items (A/C, hot tub) are costing me versus my normal electrical stuff (main sub panel). I already get historical usage data from my electric company PG&E, but not real time/last 24 hours. I’m planning to use this to supplement. (I also use Home Assistant, which I plan to integrate with using JSON, so I can get alerts when power usage exceeds certain thresholds. Like a warning to stop using the A/C so much!)
Based on what I’ve read on your documentation, and what you’ve said above sounds like I’m heading in the right direction.
If (in the unlikely event PG&E accepts my request to open the tamper sealed panel with the mains) I could somehow get 200a CTs on the mains, is there any benefit in this situation? Or since I’m already putting CTs on everything else would it just be redundant?
On an unrelated note, I’m lucky enough to be able to mount the main iotawatt unit in my garage (there is already an unused conduit from the outside panel left over from an old project). The regular 110v outlets there come off of the main sub panel. Is it okay to connect the Voltage Reference transformer to one of those outlets? Or do I need to pull a circuit off of the outside panel directly?
Lastly, what’s the maximum length the CTs cable can be? The main sub panel is about 50’ from where the iotawatt can be mounted. Could I use 3.5mm extension cables to route additional CTs to the main sub panel (and so avoid having to buy and mount a second iotawatt main unit over there). Not sure if resistance from the extra length would too severely impact accuracy/functionality.
Again thank you so much for your prompt replies, and stay safe!
