I just acquired a TRUE GDM-6 and am in the initial stages of planning a BrewPi build (the newest version is arriving today!)
My goal is to make the exterior of the TRUE as clean looking as possible. Hence I came across the SSR Expansion board.
According to the product description it seems like I could have only a single OneWire coming out of my BrewPi and going into the fridge, thus hiding the extra SSR wires etc.
A have a few questions however.
If I want to control 2 SSRs (one for heating, one for cooling) do I need to have 2 expansion boards? This 2 OneWires coming out of the BrewPi?
In the product description it says you need to use a “gray connector” to connect two SSRs. What product is that in the store?
I think that’s it (for now). I’ll be updating my progress in the fridge build board for all to see as I run through this.
