New Replacement Microwave - Will it be Detected?

I have a second Sense coming but that is already spoken for, for another purpose. Getting my Traveller HS110 back in action (Kasa and Sense see it, but Sense hasn’t added to devices yet) and hoping that the real power draw is closer to 1.6KW. Looking at the spec sheet for this microwave drawer on the web, I see that it has slightly different specs: 120V, 14.5A inputs 1000W output power [image] And investigating the IEC test procedure, it appears that it is done with water, not popcorn (bumm…

Power Specs:
Please note the potentially conflicting power specs for both input and output.

• Output - one is using the official IEC test procedure (heating 2 500ml beaker of water), the other one is not specified,
• Input - one is 1.5kW power, the other is 120V, 14.5A, which for a normal resistive load would mean 1.74kW. But this microwave is old school, with a huge transformer and capacitor, so I assume that the the max current (14.5A) would be out of phase with the voltage, right at startup. So both specs could be correct.
