I had the same negative experience using inkbird metal probe as this guy here. But the bayite Temperature Controller with replaceable probe works great from amazon.

then there was another negative experience post in the inkbird sponsored forum but it was deleted, I don't see them as a sponsor anymore. He said his metal probe models have failed within a year.
INkbird themselves, Jinghua X. posted on amazon reviews this about their metal probe wifi model
"the stainless probes may not be perfect for aquarium, but coated the probe in silicone will help."
I put a wyze cam on the temp controller if i need to look at the temp while away. Home depot has them. Good luck.
