I have two Mitsubishi mini splits connected, but now think I wired them wrong. I followed the instructions, and pictures, here: https://sense.com/guides/dedicatedcircuit-advanced/ and made a loop for both of my second wires. When I turned the breakers back on for both units, I was getting ~50w for the fans in each. I thought everything was good. I show 12w of standby energy. My first clue of something being wrong is user @chrisd253 mentioning in this thread: What's new in: V33 (iOS/Android) V12 (Web): Dedicated Circuit Monitoring that his mini splits were using 13w and 19w in standby, but then settled down to just 5w. Mine use 12w always. Not out of the realm of possibility, but it got me thinking. I read in another thread that if both wires were doubled up, the energy usage would be double. So I went back to the installation guide and think what I did was to follow the 240/120 instructions with making a loop for one wire and feeding both through the clamps.
If I’m getting double the reading, my standby could be 6w, a lot closer to Chris’ mini splits and more in line with what I was thinking would be standby usage.
I have annotated a photo of my setup to show the path of both wires.
The green arrows show the direction of voltage and path of the wires. I have basically talked myself into the idea that I set them up wrong. I tried testing it just now by turning on my AC, but instead of seeing the 900w increase in the power meter like I see over the summer, I only got a 50w spike. I’m guessing that is because it is 46° outside and the compressor is smart enough to know it only needed to use the fan to cool down inside.
Thoughts? Did I set it up wrong? Should I redo the wiring with just a single wire going through each CT? If I do rewire, do I need to change the setup within the Sense app, or just move out the extra wire and look to see what the app says?
