Hi! After reading here in the forum it seem to me that you need a thermostat controller for every heat source right? Crazy, been watching videos on YouTube from some larger breeders and they failed to even mention that you need a thermostat controller. Either way... I am planning on having both a UTH and a heat source above tank as we have pretty cold temps here in our house.

Does each one of these devices need a thermostat controller?

Do they make thermostat controllers that can handle multiple devices?

Also been considering purchasing a digital thermostat connected to an app in my phone so it’d let me know if temps would get too low or something. Has anyone tried one of those before?

just a few questions. Grateful for this forum and for all helpful people here.
