Ruuvi Tags & CZONE

I would like to link my Ruuvi tags with the CZONE network on my boat to send alarms if, say, the temperature in my galley freezer increases beyond a threshold that I would set. Another application I want to do is to turn on the exhaust fans in my house battery battery bank if the temperature gets too high. Does anyone have a recommendation for the best way to handle that? The solution has to be fairly robust to withstand a marine environment. Any suggestions is greatly appreciated.
