Sorry no scope pics I’m afraid and bad timing because I don’t have a working scope just now. I have taken a screenshot of the output from the serial plotter module in the IDE for both the TA12-100 and ZMCT103C and hopefully this should give you an indication of their waveforms. Note the scale is the same for both outputs. I don’t have a screenshot of interference, but what I have observed is a single sharp spike in voltage, often greater that the peak voltage under load, when I switch another device on or off.
