So, you have filled your hot tub with water, lit the wood burning heater, all that‘s left to do now is to sit back and wait for the water to warm up, right? Well… Usually you’d have to check the water temperature every so often, which means leaving the warmth of your home and braving the rain every twenty minutes or putting down that suspenseful mystery novel you were so enthralled in or leaving an apple pie in the oven unguarded! Is there an alternative to this? Introducing the new Bluetooth thermometer – the smartest way to measure temperature. Just plop the thermometer into the hot tub, turn on the Bluetooth connection on your phone, set the desired temperature and the app will notify you. It requires no Wifi or 4G connection! How’s that for smart technology? Sit back, relax and let the Bluetooth thermometer work its magic.
