New releases winter 2025

December 29, 2025
Software

I finally got some time to finish of all projects i have been working on during the second half of 2025.

Gravitymon

Gravitymon got support for some new boards to but to make the project maintainable i had to drop suppport for some of the older boards. Now it supports the ESP32 C3 Zero and ESP32 C3 Super Mini.

I also managed to get my own PCB design completed, the first versions were based on the iSpindel schematic, but in v1.2 i converted everything to 3.3V logic so i also can use the new ICM gyro.

On the software side i implemented some gyro testing features for the MPU6050 since i had a few users that had problems with bad gyros. This is still an experimental feature but could at latest give some indications if the gyro is faulty. The calibration now does a timeout if the gyro is bad so it will not hang forever.

I also refactored and optimized the UI which reduces the memory usage by 30%. Its still not enough to upgrade to Arduino core 3.0 since that requires +200k which I dont have room for with the current flash layout.

Another nice feature is the charging pin function that will disable the device (enter deep sleep) when charging with a wireless charger.

Another addition is the possibility to send BLE data via the RAPT protocol, both v1 and v2 is supported.

Gravitymon Gateway

The next one was to complete the Gravitymon Gateway where I added some new layouts for the TFT display, but the main things was to get a simulator for the UI that i can run and test on my Mac for eaier and quicker development. I have some plans for more UI in some of the upcoming projects for 2026.

I also added mDNS scanning in the gateway so i can map ble data from devices and display their names instead of just chip id addresses.

Gravitymon Gateway also supports receiving the RAPT v1 & v2 data but only for displaying the values. I also fixed the RSSI and TX power values which was not handled correctly before. The same goes for invalid data in the BLE packets.

Chamber controller

My version of the brewpi temperature controller got some new minior improvements and bug fixes.

Pressuremon

One some minor updates and fixes.

Kegmon

The last one out was an update of Kegmon, mainly to update to the latest dependecies and some small bug fixes.

Whats next ?

For 2026 i have plans to update Gravitymon with some new features and small fixes. But the big one is to really take on the Kegmon 2 project to move that forward.

Happy brewing, Magnus
