You've done a bloody nice job mate! I just love the versatility of the RPi! Looks like we have used the same size jaycar box! Pity they dont make one a smidge bigger... Yeah the no "Made in Taiwan" label on my SSR's gave it away. Will keep using them til they die and will do a bit more...

Thanks burrster point taken, do you have any reccomendations in regards to earthing out the heating element itself (given it only has a 2 pole live/neutral on the element with no third grounding terminal)? Cheers mate much appreciated

Not a silly question at all coolnerf! The 'Aux' temp is just another temp sensor. For example given the DS18B20 temp sensors are waterproof currently I run the "thermowell temp" sensor in the thermowell at the bottom of the kettle and just for curiosity sake put the "aux temp" probe into the top...

Hasn't been an issue at all matt - the RPi actually gets hotter than the relays. Have done so already burrster. What leads you to not be convinced that it isn't safe; the lack of earthing given all the third pins on the IEC's don't have connections? Cheers

Tidy up complete. Updates to be posted once pump arrives! HERMS build shouldn't be too far around the corner utilising more budget pots...

Slowly tidying things up...

I've been contemplating ordering a 4B for my entertainment unit Pi - Would you be able to post and update on how it goes on the Brewery front? Also were you running CBPi 2 or 3 when you were having stability issues?

I can't seem to find a wiring diagram for the PCB of the robobrew and am not 100% sure how the relays in them work when you are in "play" mode. Going off gus' original post it looks like the 8 pin serial wire (with the 5V 1900W element wires etc) appear to be the signal for the onboard relays...

Only thing i could foresee being an issue would be the temperature probe. CBPi is designed out of the box to us DS18B20 "one wire temp sensors" (3 actual wires but you can run a bunch of sensors to the same GPIO pins and are compatible with the RPi 1 wire settings) and I assume the RoboBrew is...

Meddo, I found all reliability issues with CBPi and my RPi 3+ were solved by upgrading powersupply to the Pi. Instead of using the OEM Pi power supply I went to a dedicated Mean Well 5v 3A Switching PSU from Jaycar and hasnt missed a beat since. Just run 240v AC in and then get an old MicroUSB...

How did you go with spare parts steve? May be able to help with craftbeerpi and robobrew conversion side of things, quite familiar with both. Cheers Mick

Some further pics for those interested:-

Hello AHB Crew, Thought I would share a few pics of my frankenstein CraftBeerPi rig capable of currently doing 10L AG batches but built for expansion. First brew under the belt on Friday night and it didn't skip a beat. Ultimately heading for a HERMS system but have a few life things going on...
