Cheers to Elco and the BrewPi Community -
Looking to dive in once V3 is released and I’m putting together a parts list based on the latest Spark posts and gleaning what I can from the significant history of the BrewPi ecosystem.
After reviewing the “Fridge Hacking” guide, I’ll be opting for an external “Switched Power Cord” to control the Fridge compressor and heating elements directly. (I realize that this will leave the existing thermostat in line and could result in conflicts at lower temps, but the True GDM-07 Commercial unit I have is able to approach freezing before toggling naturally when at “max cool” setting - I don’t expect controller fights at ferm temps)
I’m also opting for this choice so the result is “portable” between fridges easily, pending fridge upgrades.
Regarding “Switched Power Cord” options -
I’ve seen back and forth on multiple forums regarding Mechanical vs. Solid State relays for this portion - Heat, switching speeds etc. Many on the “plug-and-play” mechanical side opted for the PowerSwitchTail II, but I noticed they also offer an SSR base option, the PowerSSR Tail.
(Given I’m expecting to purchase a V3) It seems like the SSR option is cheaper, meets spec, and is more robust than the mechanical route. Any issue going this way?
EDIT: I suppose Mech vs. SS relays may operate differently to the “control” signal sent - Looks like the Mechanical one fails open…What would the SS version do?
