Temperature and Fermentation control using Tilt Hydrometer??

    Hi all

    I am looking at purchasing a Tilt hydrometer and am wondering whether anybody knows if it is possible to have the unit control the temperature during the ferment. I know it can output the current temperature of the brew so you can see what the temperature is doing, but I am keen to see whether anybody has created a setup where the device can effectively turn off and on the fridge / heat belt (or mat) to maintain temps in the fermentation chamber.

    I have an STC-1000 but I'm not sure if that can be used with the Tilt to get temperatures right at the heart of the brew and then control accordingly.

    Cheers

    Thanks.

    The new Tilt's have wireless in as well making them a touch more versatile than the original version.

    I will take a look at the links. If anyone else has an input would be keen to get your view.

    Tilt has no control. However there are some DIY projects on HBT that will, and also integrate Tilt info all on one screen. (note I haven't followed the threads there for some months so they may well have advanced further).
    My fave is Brewpiless, but it don't work with tilt, one of it's sister projects does they're all in the same sub forum.
    Note this is an 7/10 on the difficultly DIY scale, you'll need some soldering skills, some knowledge of basic electrics or a friendly sparky to help out. The software side is medium to easy if you follow the directions.
    The Ispindle above I'd call an 8/10.

    This is where your hobby starts a whole nother hobby for ya!!

    ED: Fermentrack the project that links Tilt or Ispindle to brewpi, including multi chamber support all on one screen. Had to go do a bit of searching said it had been a bit.

    Thanks for the reply.

    I suppose the question should be do I actually need to really bother about this level of complexity. I am interested in a Tilt and am likely to go down that path and I have a spare Pi or two so that's not an issue.

    Should I just stick with my STC-1000 for controlling temperature (heat belt wrapped around my Fermentasaurus and inside the fridge) and have the Tilt there to just provide gravity readings and more detailed temperature info?

    Thoughts welcome?

    The guy who wrote fermentrack also designed serveral PCB's for brewpiESP8266, these were fairly simple to solder up. The one I have has I2c for LCD, pin out for double relay board, and an RJ12 for sensor output. It uses a 5v wall wart and is wifi. Maybe an hour of soldering all up. stick it all in a box and you the most accurate ferment control out there. Installing fermentrack is a single command, flashing any brewpi is done with the click of a button in fermentracks control panel(the brewpi plugged into usb).
    Note the Tilt costs around $200, for that money you could build 10 Ispindles.

    STC1000 will hold a temp within a deg or two, brewpi uses a predictive algorithm and will hold with in 0.2 c actually if you follow the graph of beer temp, there will be a spike (down) when active fermentation stops. Obviously you have to go to your ferment fridge to check or adjust your STC1000, fermentrack you can check and adjust (with correct network settings) from anywhere in the world. Is it something you NEED to do, you will still make good beer with an STC. However if your going to get a Tilt anyway having SG and temp on one graph is way more intuitive and meaningful.
