SPINDELMATE (Yet another iSPINDEEL, TILT hydrometer and RAPT PILL datalogger and temperature controller).

[kbaggen]

HOME: GitHub - kbaggen/SPINDELMATE: A ESP32 Hub for iSPINDEL, Tilt Hydrometer and RAPT PILL.​

SPINDELMATE is a fermentation logger capturing the TILT hydrometer or RAPT PILL data of gravity and temperature by Bluetooth or WiFI signal from iSPINDEL. Furthermore, it is a cloud service allowing to easily uploading your data.

It is based on ESP32 and supports Shelly, Sonoff (DIY mode) an Tasmota Plugs for controlling a fridge or heater and hence secondly acts as a temperature controller. These plugs is controlled over local network by HTTP commands.

All data and controlling is done at SPINDELMATE CLOUD and hence you only need to enter wifi details once in the logger.

Parts needed​

An ESP32, a usb cord and a TickTax box to hold it all, and ensure some moisture protection. Currently, it have been tested with ESP32 DevKit1, ESP32S NodeMCU, and Wemos ESP32 D1 Mini (se more below). If you wish to use the TempControl function you will need Shelly Plugs and/or Sonoff Plus in DIY mode (se more below). Tasmota Plugs also supported.

Hello There. It would be great to talk to you about this. We are in the process of mass producing a new board with ESP32 with OLED 0.96 inch screen and 4 buttons. The board and device is primarily used for our new digital regulator and digital spunding valve but the same board could be purely used as a bluetooth bridge. As we are mass producing the board we should be able to supply the board and a suitable injection molded housing as an OEM part.

So if you wanted to do this project we can probably assist in this way to help you get started. Please PM me if you want to take this further.

Dear Kegland, thanks for reaching out, always nice to be noticed by the pro´s

I will try contact you, but in general this is meant as spare-time project (and so is iBLOPPER). If I would ever make some business over TILTPILLMATE, it would be by people doing the DIY building themself of installing on a ESP32, and hence, letting people donating a minor fee for the software/cloud service each year mainly to support the server if every needed.

I dont think I ever would get the spare-time to run a full business of selling such boards however the fun it could be. The nightmare of faulty parts, and getting this sold in at distribution etc., would also not be the strong side of a microbiologist

No worries at all Klaus. Well we will do what we can to help and we will try and collaborate with you. At the end of the day we will be putting the money and time into developing the boards anyway so we are happy to share what we have with you. I will continue the discussion with you via PM.

RAPT Digital regulator and spunding sounds awesome. I have been working on this for a few years with some success some failures. Looking forward to seeing a commercial product.

 

[kbaggen]

UPDATED till ver1.1.0, and now supporting iSPINDEL too.

 

[Oberhauser]

Thank you for the new version 1.3
I have the problem that my raptpill sent the data but the spindelmate only receives 00 for all the data.
Can you be so kind and help me?
Best wishes

Michael

Hi there, it seems that after the firmware release of 17 march 2023 Kegland has changed in the telemetecic data , and hence, from firmware 20230317_094939_9285ef0 SPINDELMATE cannot read the bluetooth signal of the RAPT PILL..........I havent had time to look into it and hence unsure if I can fix it nor if it is worth duing such an game (if it is a game so to speak

We have been changing the pill firmware recently so we now also have the pill giving out a new figure which is called "Gravity Velocity". The pill will average the past 180 readings (and delete outliers). It then takes these readings and works out the fermentation speed (AKA Gravity Velocity). This is essentially working out the slope of the graph of readings over time.

This figure is an important figure and it will enable us to have more robust fermentation profiles that will help us maintain an certain degree of activity in the yeast rather than just fermenting at different temperatures over different times.

The 180 readings that it averages can be taken over 6hrs, 12hrs, 1 day, 2 days or 3 days depending on what you set it to. We are going to do a video on this in the future.

 

[kbaggen]

ok, so this number will tell you how much the pill moves/jitters around and hence something on the activity of the yeast/fermentation?

SPINDELMATE version1.4.0

• Updated code for PILL identification as KEGLAND changed the RAPT Pill telemetric data, and hence, need new way to identify RAPT Pill´s. Therefore, please use "100" at "TILT Color/RAPT Pill/iSPINDEL" at setting. This find all RAPT Pills and hence if you have more than one you need to remove one from room and secondly get serial output on to get the mac-id and use this found mac-id instead, e.g. for instance 78:e4:8d:4d:21:4c. You can use Brewflasher, ESPhome flasher or Arduino IDE to show the serial output and just await it list the found Rapt Pill after Bluetooth scanning is completed after some minutes. Please NOTICE! The mac-id is slightly different than KEGLANDs Unique Device Id for some unknown reason, hence, serial output is likely needed for all users with more than one Pill.
• AP mode for iSPINDEL has been removed as having SPINDELMATE in both AP (access point mode) and STA mode is giving instability issues. Sorry, metal fermenters users.
• Stability code enhancements.
