I am looking for a thermostat that is powered only by batteries that can turn one of my circulators on wirelessly. I have a new Viessmann Vitoden 100W boiler, and a Taco relay that is connected to two separate thermostats and circulators for our small 2 zone house. The problem is that I want to move one thermostat to another room without tearing thinks up to try and run a thermostat wire to it. I have researched ”wireless” thermostats, but have found nothing that doesn’t require a thermostat wire. I’m looking for something simple, that could communicate like Bluetooth to a receiver in the utility room 20 feet away, or, if necessary, via the internet to just turn the circulator on and off. Does such an item exist? Thanks in advance.
