    Yet another DYI Plato scale

    Sure, give me a link to the display you consider and i can see whats possible.

    Yet another DYI Plato scale

    Just published a new version. https://github.com/mp-se/kegmon/releases/tag/v0.6.0

    Replacement firmware for iSpindel (GravityMon)

    This was interesting. Was there any buildup of kreusen on the 6500 ispindle that could cause it to show a different angle? Another option is that the 6500 has different accuracy based on temperature...

    Replacement firmware for iSpindel (GravityMon)

    Don't think so. It should only be affected by the sugar content.

    iSpindle Concentrators, Repeaters, Bridges, Hubs

    Does it wakeup as intended? Could be an hardware with the iSpindle issue if it only reports once. Check the resistor on the RST pin (think its called R1 in the schema).

    Replacement firmware for iSpindel (GravityMon)

    Looks really good and thanks for the kind words. Would be interresting to see the difference of the gyros, i have not used the 6500 myself

    Replacement firmware for iSpindel (GravityMon)

    It looks like it crashes when trying to do a wifi scan for what networks are available. But I dont really understand why..... Do you have lots of wifi networks in your area ?

    iSpindle - DIY Electronic Hydrometer

    You can use my gravitymon software as well, it will work without any sensors (you will get prompted about them missing but it will start). Unfortunately the ispindle wont start unless all the external devices is in place.

    Replacement firmware for iSpindel (GravityMon)

    After some digging into the error codes here are the failure codes from the "connect to wifi" 1 = No SSID available, so this would mean that it failed to connect to the defined wifi. Could be wrong SSID or poor coverage. 7 = Disconnected, the connection has been terminated for some reason.

    Replacement firmware for iSpindel (GravityMon)

    This is a good log. The first part of the line just refers to the part of the code where the log comes from. Help = Helper functions, Cfg = Configuration. There seams to be some kind of crash in the code (exception 28) which is probably the reason for the wifi connection problems, it will...

    iSpindle - DIY Electronic Hydrometer

    You need to complete the build or it wont start at all. You get the json error because it has not saved any config yet

    Replacement firmware for iSpindel (GravityMon)

    Released the official v1.3.0 now. No changes from the beta3 expect it does not say beta3 anymore. https://github.com/mp-se/gravitymon/releases/tag/v1.3.0

    Replacement firmware for iSpindel (GravityMon)

    Then you didn't do a full erase before the flash. Brewflasher has an option to do a full erase. A normal flash will only erase part of the memory leaving parts for the file system and wifi settings intact. Gravitymon will find old credentials and try to use them (Even from other wifi enabled...

    Replacement firmware for iSpindel (GravityMon)

    That should be correct, looks like the ispindle website. If you used 470k instead then it will not restart correctly after a deep sleep.

    Replacement firmware for iSpindel (GravityMon)

    I would bet on that this is a hardware issue not software. It looks like to manages to go to sleep but not wakeup again. Check the resistor / diode between RST and D0 that is most likely the problem. Either wrong value of the resistor or wrong direction on the diode.

    Yet another DYI Plato scale

    Is likely that there is not enough power from a GPIO pin towards the DHT22, I modified my build with an transistor to ensure that there is enough power and I steer the transistor with the GPIO pin. I added an CAT6 2m cable and there was no drop in voltage over that distance so its probably a...

    Yet another DYI Plato scale

    Well this might be worth testing in practice. I will build another scale base and put that under my fermenter to collect some data.

    Replacement firmware for iSpindel (GravityMon)

    I've been running the latest beta on my current brew and it works correctly on my services. Can you use the "Gather support info" function and send me the result so I can check your configuration ? You can do it in a PM or open a ticket on github.

    Yet another DYI Plato scale

    So if you have a 23 liter batch (make that 23 kg for easy math) and the alcohol content is 5% that would mean that the alcohol would weigh 23*0,05=1,15kg and the co2 weight would be 1,265kg. Would the weight then be reduced by 1.265 kg or the difference between 1,15 and 1,265 (165 grams) ?

    Replacement firmware for iSpindel (GravityMon)

    I Try to do a reflash with full erase and see if that improves things. There are occasions when there have been corrupted memory on the device that can cause issues. Try to connect with another device, phone or tablet and see if that works better. You can also try to move the device away from...
