Replacement firmware for iSpindel (GravityMon)

[larsh]

new beta released that should fix most of the bugs that have been reported. all releases are available on github and on brewflasher.

Release v1.3.0 beta 3 · mp-se/gravitymon

Features Refactored log output from WifiManager to be consistent with other logs. Issues adressed BUG: Double reset was detected incorrectly on ESP32C3, created own code and dropped douoble rese...

github.com

Since there are a few boards being supported right how I would like to know which ESP boards are of most interest so I can focus on testing those.

These are the ones that are supported right now:

1. ESP 8266
2. ESP32 D1 mini
3. ESP32 C3 v1.0
4. ESP32 C3 v2.x
5. ESP32 S2
6. ESP32 LITE (Floaty)

Double reset and WiFi config was a struggle with the ESP32-S2 too. Seems to be much more reliable now with the 3x taps in beta3.
With the 2x taps, I found some tricks to come through WiFi config:
* Temporarily configured the phone to "Forget" my ordinary home WiFi
* Tapped RST not too slow, not too fast. A few cut-and-tries to find the "sweet spot".

With the 3x taps, I do not need to "Forget" my home WiFi.
The not too slow, not too fast -tapping is still applicable.
AP delay is also shorter.

I have just finished a Schwarzbier with kveik @33 degrees Celcius running beta2 on the Ispindel.
SG was spot on all the way.
The Ispindel was in the fermenter partly during cold crash too. It did not like that temperature very much though

Thanks for the feedback, good to hear that the enter wifi is working better. I will update the docs to clarify on the frequency. As you mentioned the you cant be to fast to do the tapping, an interval of 1-2 seconds would be optimal, not slower than 3 seconds.

Most of the wifi issues was connected to the Arduino framework. There was a 60 second timeout as default on the esp32c3 and esp32s2 boards for some reason and this didn't affect the other esp32 boards. So this is why it was slow to get an access point on those devices. I reduced that down to 1 second which seams to work better. The serial logging is also improved so its easier to see what is happening.

Glad to hear that the measurements was spot on, that's the main purpose of the software. Did you enable the temperature compensation formula or did you build that into your own formula?

I enabled the temp compensation formula. Maybe the formula did not like such drastic temperature changes over that short time. When I started cold crash, SG fell from a stable 1.014 (same value measured with a hydrometer) down to 1.005'ish.
If you wonder about the "notch" as temperature was falling, it's because I opened the fridge door to

cool down fermenter to basement temperature (+12C) before closing and cooling further down to +5C

It could also be caused by my spindel construction:
Inspired by the Thingiverse projects #3271613 and #3666038, I designed some parts to make the CherryPhilip fit into an XXL petling. Much more volume/air in that one vs the original XL.
On the other side it is heavier. Clocks in at around 178g, quite similar to the "Hydrom" hydrometer.

The temperature drop should not really have an impact unless it affects the ispindle tilt somehow. I use the same correction formula as many of the online calculators out there which I hope is correct.

If you got a correct value of 1,014 at 32C then the measured gravity before correction would be 1,011, if I apply the temperature correction at 8C then the value would be 1,009 using the formula.

Google Translate sez:

"I tried this software v 1.3.0 beta latest version, when I first run it, it sends information to brewspy address 1 time, then it does not."

Also...Merhaba m_sahin45! Ve Homebrewtalk'taki forumlara hoş geldiniz!

Cheers!

I did a quick online translation of his message.
Seems to be in turkish and something like this:

"hello, I tried this software, v 1.3.0 beta latest version, it sends information to brewspy address 1 time when I run it for the first time, then it does not."

I had gravitymon setup on one device, but through a series of bad choices I've reflashed it and now cannot manage to connect to the "GravityMon" wifi from my pc or phone. I see the network, try to connect with "password" and then usually it fails to connect. Occasionally my pc will stay connected, but I cannot load anything from 192.168.4.1. any thoughts?

 

[DuncB]

Are you trying to connect to the gravitymon network on 192.168.4.1?
Try this from a device near the ispindel.

correct, I'm getting to get into 192.168.4.1 when connected to GravityMon wifi but no luck and the ispindle is right next to my phone and pc

 

[DuncB]

Have you redone this step? And saved it?

Can you explain in more detail what is not working? What are the steps you have done ? Are there any errors in the error log that might be relevant? Have you followed all the installation & configuration steps ? Is this problem only on the 1.3 beta or does it behave the same on the 1.2 release ?

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 the computer and try again (could be interference).

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.

As seen in the photo, the device sends information once, then does not send it, when I restart it, it sends again.. I have uploaded many times and it has not changed.

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.

i will check is this schematic correct
