Yes you right, I only advised Aqara as a fullest line of available devices… if you only want a heater control and nothing more via Internet, well TP link could do job, yes, absolutelly.I've looked into Aqara, but from the best that I can tell the platform isn't programmable via user-defined scripts.
I'm thinking out of the box with respect to monitoring heater performance. I don't need a $600 dollar reef controller (or even a $40 Inkbird) in order to pull that off when a $15 TP tapco wifi smart plug will do the level of monitoring and even more so in some aspects.
