Very excited about this piece of hard/software that arrived today, but can’t seem to get started.
Quick facts:
- New IoTaWatt system with 2x
AcuCT-H063-100
and aJW-95001-NA
(+ provided USB adapter) plus a bunch of other CTs still in the box. - Live in a standard US apartment with split 110/220v power, nothing special
- Engineer with decent EE understanding and previous experience with horrible (accurate but unreliable) z-wave energy monitors.
Problem:
- 1 CT is constantly under-reporting by a lot - it states constant 10-20W when each phase is usually over 100w at least
- If I turn on the garbage disposal (which feeds from the “faulty” phase), it constantly displays <250W (it’s a 3/4hp motor). My electric kettle measures just about right 1600W with the “good” phase, but <1200W with the “faulty”, so it doesn’t seem like a linear issue.
- If I swap the CTs, the “faulty” CT will bring the problems over, so the affected phase will suffer now
- Now here’s where it gets interesting: if I connect both CTs to the same phase, they display +/-10W!
The whole this is obviously under-reporting (main1 + main2 don’t even add up to my 3d printer measured outlet).
Attempted troubleshooting
- Read, re-read and re-re-read the CT’s model numbers against my configuration
- Squeezed the CT tightly with no change
- Physically and virtually reversed both clamps
- Was ignored about my huge issue by my spouse
Thanks in advance. I have also provided a pic from my setup and config. Order #127095 (July 18, 2022), if it makes a difference.
