Same problem as yours with rpi_focuser.

I run astroberry-server on a RPI3 and I am very happy with it.
All updates have been done (astroberry scripts and mate packages.

I am less happy with my actual focus motor and so I have tried to use the rpi_focus.

I have installed INDI Astroberry from the .deb file at and I believe I used the required procedures (i said: I believe).
When I try to load the indi_rpifocus driver in indiserver (through graphical interface of EKOS configurator), no Astroberry Focuser tab shows up in focuser list.
Here is what I have done:

# from
# download the latest version of the library, say bcm2835-1.xx.tar.gz, then:
tar zxvf bcm2835-1.xx.tar.gz
cd bcm2835-1.xx
sudo make check
sudo make install

installed armf rpi (.deb) packaged indi driver (rev 1.04)
# not done what follows since I use a raspi3 and this is
# for RPI2 enable device tree support
# and I have not found that kind of setting in the raspi3 version of raspi-config
# sudo raspi-config
# under Advanced Options - enable Device Tree

I have also tried to install this afterward in the hope to get missing libs
but this does not seem to improve anything:

sudo apt-get install sense-hat

The rpi_GPS appears in the picklists but no rpi_focuser

Any idea ?

Hi there,

First of all thanks again for your super application !
I love it.
I am currently trying to replace the dc motor of a nFocus by a 28byj-48 stepper (modified 4 wires see here: and drive it directly with a drv8835 from the raspi GPIO.
My question is : is the astroberry focuser driver already included in your astroberry server ?
