3phase iotawatt ct inputs above.
These are from my friends Iotawatt. I think he’s reversed them as positive numbers are grid import, negative are grid export. I tried chatgpt to code up something to invert the numbers and then split the positives and negatives (import n export to grid). The furtherest I got on chatgpt was both imp/exp sensors read the same value. Any ideas? Coding isn’t my area. Considering CT’s go negative and positive, I’m unsure why HA only reads positives. Thanks for any help.

There is a checkbox in the iotawatt for each input that allows you to reverse the CT direction in software.

Yeah getting his ip n user pas for iotawatt now.

Would that code have actually worked ever? I’m guessing reversing will fix some issues

Then do you add the same 3 ct sensors to grid and export or make a export template solar production minus consumption?

Also can’t see web etc cameras through tailscale annoying to try set up. He’s gonna owe me some empire tech cams haha. And you guys some tips. Wish I understood the coding side better.

Can energy dashboard have any negative value? I tried to get 2 sensors for each phase to split the negative or positive, convert to individual positive numbers. The cts will swing negative when consuming on a reverse.

This code gives unavailable.

See: https://www.home-assistant.io/integrations/iotawatt/#configure-iotawatt

No. Production, consumption and return should all be positive values.

Made input output sensors on iotawatt.

(Ct min 0) Abs and the other max so hopefully it’s always positive.

Ct sensors are bidirectional. They go negative during grid export usually. One on solar can be unidirectional but you need bidirectional for consumption and export tariffs.

For power devices it isn’t needed but grid entry needs bidirectional. Batteries too.

Ahhh that document had the answer I was looking for , for so long omg. I feel d U m b lol
