Immersion tank remote temp probe

[bigspark17]

Hi i would like some kind of standalone cylinder stat that can send the tank tempreture to a display, ideally wirelessly.
Situation, immersion tank in attic space, immersion switch/boost in hallway. Mixer shower & bath in bathroom run off tank, customer never knows if water is hot enough For bath or shower without turning on, some kind of display would eliminate this if such a product exists??

This was my first Google result.
You could have it just as a display rather than connect it to control the temp.
