The issue occurs, if the following conditions are met:
- Moitessier HAT revision older than E05 (see the imprint on the bottom layer of the PCB board), i.e. any board without shutdown button --> also referred to Moitessier HAT 1 (green PCB)
- Firmware older than 1.4.0 (read firmware app version: ~/moitessier/app/moitessier_ctrl/moitessier_ctrl_$(uname -r) /dev/moitessier.ctrl 1)
- OpenPlotter V2
There is no issue using the Moitessier HAT 2.
To fix the issue, you must detach the HAT prior starting your system, otherwise the installation will fail. The mentioned steps only have to be done once. All subsequent updates can be carried out as usual once the firmware update has succeeded.
Proceed as follows:
- Shutdown system and detach HAT
- Restart the system and log in
- Open a terminal and execute the following commands:
cd ~/Desktop
wget https://get.rooco.tech/moitessier/buster..._armhf.deb
sudo dpkg -i moitessier_1.20200114-1_1.5.0_armhf.deb
- The firmware update will fail after several retries, because the HAT is not attached. However, the linux device driver is updated correctly.
- Shutdown the Pi
- Attach the HAT
- Restart the system and log in
- Restart package installation via terminal. Firmware update will succeed as well.
sudo dpkg -i moitessier_1.20200114-1_1.5.0_armhf.deb
Please test the new driver and report if there are still any issues. We will publish the new release afterwards. Thanks a lot!

it worked on my raspi 4 - but only after having first enabled I2C and SPI interfaces in the raspi
config. Thanks Thomas!
Please consider to add to the install program also a setup option, which loads a script to configure the signalK, serial and I2C options for the Moitessier-hat. It really cumbersome (although great for familiarization and learning :
to do all those steps necessary for configuring the pressure sensors and gps.
