yeah that is what it looks like in brewfather plotting both the Ispindel and brewpiless. 2 beer temps(light blue/purple), the fridge temp(light green), pressure in orange, ispindel voltage in dark green. I probably need to calibrate temps as the Ispindel and thermal well shouldn't be 2 degrees apart.My ispindels don't have the cap above the liquid. Always at least part of the cap in the liquid. We'll see if things are tighter with the oring arrival, but agree with you this was a one off sinking and maybe the heat didn't help.
There's a lot going on on that graph but I think I've worked it out. The two temperatures are the cabinet and the beer ?
How do you measure the pressure? I have wondered about those tyre sensors that relay to the car but they only turn on with movement I think. My fermenter isn't rolling about.yeah that is what it looks like in brewfather plotting both the Ispindel and brewpiless. 2 beer temps(light blue/purple), the fridge temp(light green), pressure in orange, ispindel voltage in dark green.

I hope it's not leaking?
I'm at a loss to explain my earlier problems with my iSpindel and Repeater. After it stopped reporting towards the end of the fermentation in my last batch of wine, I gave the iSpindle a full charge then just set it running again, recording and sat on a shelf. It took a few attempts to get it going, but it began working on the 2nd May, now the 23rd and it is still reporting just fine, every 10 minutes and reporting the iSpindel's battery volts as 4.08v.Just to update - The iSpindel + repeater on soak test are still working and reporting 48 hours later.
I HAD IT WORKING !!! (insert here a video of a mad scientist).
Try a formula with less digits behind the decimal point(who needs 22 decimals?!) and replace the last tilt^2 to tilt*tilt.ughhh I switched the wifi network to my iPhone personal hotspot and that did the trick. So I recalibrated the ispindel ( was a bit sloppy for the initial calibration and wanted better numbers that weren't all over he place), replaced the formula and the device won't upload anymore. I gave it a week, but nada. I suspect there is an issue with the formula that is preventing it from connecting. Back to the drawing board.
this is what I am using

I did all that except I haven't been able to determine if my iSpindel is reporting in Plato.From the brewfather documentation:
Make sure your iSpindel reports gravity in Plato (it will be converted to SG) and temperature in Celcius. Add [SG] to the name of your iSpindel if you use SG based formula. If the gravity is displaying 1.004 in Brewfather you are using the wrong formula, use the formula that reports in Plato or use the tag above.
If you get no gravity reported: Check that the formula is not too long.(as of 6.5? of the iSpindel firmware it is 250 characters; what the max. length is in brewfather I don't know), There's a max character length. Instead of "tilt*tilt*tilt" put *tilt^3"(instead of what I told) etc.
If it still fails: Upgrade to the latest iSpindel firmware or try to use the second degree polynomial formula for your iSpindel.
Where did you get the formula from?except I haven't been able to determine if my iSpindel is reporting in Plat
I used the online formula iSpindel CalibrationWhere did you get the formula from?
What version of the iSpindel firmware do you use?
Reporting only once could indicate that there is a hardware problem where it can't get out of deep sleep for some reason. Google: iSpindel deep sleep
You can actualy specify the gravity units there, default is SG, if you did not change that your formula is SG and you should add [SG] to the name of the iSpindel in order to let brewfather know the iSpindel is reporting SG.
I had a 5v 100psi stainless sensor from an engine project I never did uhm 20 years ago. The range is not ideal but with the proper RC filter I get a decent reading from the brewpiless. It is just teed into the spunding valve connection. Took a while to find the fittings to go from 8mm tube to 1/4" male pipe.How do you measure the pressure? I have wondered about those tyre sensors that relay to the car but they only turn on with movement I think. My fermenter isn't rolling about.
If your thermowell is at the bottom and Ispindel at the top could be a temperature difference especially as a couple of fahrenheit isn't that much.
I must set up a brewpi or equivalent and get this extra info and control you are garnering.
Have you a URL for the repeater updated firmware?Ideally this software and some display software -+ brewpiless all on the one esp8266 although that might be demanding too much memory etc from this device.
I did notice that after several days of signalling from my ispindel to the repeater that the blue light was on all the time instead of only flashing when it sends a signal. I'm not sure why or if this is contributing.
Do you do a hard reset of the repeater using the button or unplug and restart to get it working again.
Are you logging during this dry test and if so have you looked to see if the memory area for this gets filled up and causes a problem perhaps the bootloop?
