Wiring a onewire temperature sensor to multiple Brewpi Sparks

I have 3 fermenters each with their own Brewpi Spark 3 and onewire temperature sensor for the beer temperature. I would also like to monitor the temperature of the glycol chiller fluid and have this reading on each spark. Is there some way to wire this with a single onewire temperature sensor or do I need one temperature sensor per brewpi spark?

If you want to show glycol temp on the Spark’s screen you’ll need a sensor per Spark.

If you want to show data in a UI graph, you only need a single sensor connected to any one of your Sparks.
