Smart Thermometer

Hi Everyone

Does anyone know of a thermometer that would sound an alarm when temperature thresholds are breached?
I know you get smart controllers that can email and sms etc but something that beeped every couple of minutes would be really simple and helpful.

My heater bombed out on the weekend and only realised quite a while after.

Something like this would have helped quite a bit

There is an intelligent heater but it does not beep. It flashes red when the temp is too high and blue when the temp is too low. Also not sure if you can get it here in South Africa.

Maybe try a product like this:

Although I think the Seneye product maybe better due to other parameters you can watch
