    Let me know how you go setting the tilt formula @Nullnvoid.

    I was also very impressed at how easy it was to integrate with brewers chronicle.

    The tilt formula was already loaded? I didn't have to do anything. I possibly need to push it down the tube a but more it's about 2 points out.

    And yeah very easy to integrate with brewers chronicle!

    Yeah, mine was loaded too. But when I put the it in my first batch I checked the hydro v the ispindel SG and they were vastly different

    Sorry, I don't know enough to help you. I am assuming you need to try and get the parts pushed down the tube further so that you achieve it closer to 25 degrees. Maybe one of the other gurus will be better placed to help!

    For what it's worth, I probably won't be using mine for a definitive number, rather a guide to how fermentation and my temperatures are going and will still use the Hydro for the final reading.

    My question is, how often does the battery need to be charged? Does it need to charged after each brew?

    If you like Russian Roulette, then charge whenever, otherwise why wouldn't you charge after each brew

    I have just finished a brew and have taken readings twice per day, I'll use those along with the recorded tilt to update my equation

    I've always set mine up as close to 25 degrees as possible and take a calibration point. When I put a new brew down with known gravity from a refracto, I use that as a calibration point. Usually a mid fermentation measurement or two can't go astray. I use mine as general guides for fermentation, it's generally bang on when I test. The more calibration points you take or setup using sugar+water, the more accurate your results. I personally use Fermentrack which is super easy to add calibration points, doesn't need internet access and "just works". With Fermentrack you can also set calibration points whenever you feel like versus having to do anything with config mode as well.

    I tihnk I know the answer to this, but is it possible to set the iSpindel to give readings to two places, ie, Brewers Chronicle and also Brewfather?

    I'm guessing the answer is no, but you never know, if you asked me a couple years ago that I could actively monitor the ferment right the way through and I would have called you coco bananas!

    Not that I've seen. If it was supported on the device, I'd expect to see a 25-50% hit on the battery life making the extra call. I've spoken to one or two other people who have written some local web services which ingest the response then duplicate it in the correct format to however many services they'd like to send it.

    Anything is possible, from a quick look around you can configure it to send its data to any server like ubibots or https://brewerschronicle.com/KB/ViewArticle/2018/11/ispindel_integration. The problem will be pointing your software / GUI to read from a shared source, they usually are proprietary and don't like sharing. I havent played with either but you could try to find / write a programming script which can copy and repost the data across several servers, which may be an easier solution.

    Brewers Chronicle does not have the capability to forward readings through to other services, and I doubt any of the other various services would provide that feature either for security reasons.
    If BC was to post readings through to UbiDots, then it would need to have on record your UbiDots APi credentials.
    Or your BrewFather credentials, etc, etc.

    As has been mentioned (more particularly by littleJohn), you would need find someone who has written a software proxy which would receive the iSpindel readings.
    This software would then send readings to your target web services.
    And also, this software would need to know the credentials for all the target services as well.

    I never got the iSpindel TCP server working so I don't know what it actually does....
