Thanks for all of the replies. An external solution such as weight/load sensor sounds like a brilliant plan. Any recommendations on that?To clarify the project (if anyone's interested): my remote input will be offset by how far I am from the kettle - determined by GPS on my phone - how much water is currently in it, and the temperature.
I'm not sure how best to go about it
If I use a load sensor I understand I'll need some sort of an amplifier?
