This ac current sensor used for measuring alternating current, particularly used for whole building consumption or generation.This split core transformer is particularly suitable for DIY use and it works well with arduino and raspberry pi.Use this split core current sensor to build your own energy monitor, reducing your power usage, or use it build an over-current protection device for an AC load.Input Current: 0~100A AC; Length of Leading Wire: 1m; Two Form of Output: current output or voltage output (burden resistor needed to add); Cable Jack: 3.5mm (like a headphone jack).Suitable for lighting equipment, AC motors, air compressors, monitoring, current measurement and over-current protection
Yes I would put a current clamp on the wire like this

You will need a burden resistor along with the circuit he describes.
If you don't care about the voltage or watthour consumption then you shouldn't need anything else but the current clamp. I personally use esps which can be programmed with the arduino ide. However just find a nice tutorial you feel is complete(if not video above) and use what they use.
You can ultimately program it to text (via email) when some time period passes and current is still being consumed. Or to turn on another relay which can send power to something else like a light or siren etc
Skip breaking open the circuit and just monitor the current externally using something like this https://www.amazon.com/JANSANE-SCT-013-000-Non-invasive-Split-Core-Transformer/dp/B07D8SXQ13/ref=pd_sbs_328_3 It generates a current (which you can change to a voltage - just add a resistor) based on the current flowing through the clamp. This means the mains is fully isolated from the PI, Pick the correct resistor to ensure that you hit above threshold for the GPIO when the heater is on, but never above 3.3v.
Many UPS models have a USB based serial port which generate outage notification.
The next simplest approach is to rig a simple usb charger and rig a simple voltage divider connected to the ground and a gpio pin. If power drops out the gpio pin will go low.
A somewhat more complicated approach is to use a clamp on ammeter on the cord feeding the UPS like this one:

If no current is detected this indicates an outage.
