Identify Single wire communications protocol
There is no way to tell if this is a standard protocol or not from the information provided. It is not even certain how you measured the signal displayed so cannot even offer advice regarding the electrical characteristics of the signals. 

You need to be aware that the manufacturer may very well be using some totally proprietary communications scheme.

If I had to investigate this I would do a teardown of the remote temperature sensor. (You may want to purchase a spare part for this purpose). Inside the temp sensor you may be able to observe some part numbers that would lead you to component data sheets. If the one wire communications is designed to be attached to a commercially available IC chip then the part data sheet will have details of how the communications works. On the other hand if the sensor is a custom part or the one wire is attached to some microcontroller you are going to be out of luck in finding a "standard protocol".
