The Home2Ls - Smart Tools for a Private Home

home2l's Issues

Basic / productive install problems

I successfully tested the demo environment with brownies and own MQTT server.
But I can't install the productive environment properly.

After the installation according to chapter 3.3 in the home2l-book, I run home2l server and get the error below:
/usr/local/bin/home2l: Line 71: home2l-server: Command not found.
 
I run the command with home2l and root user with the same result.
The directory /opt/home2l/bin/amd64/ only contains home2l-daemon*.

 
I always used a fresh install and tested with following OS:

• Debian 11 (5.10.0-21-amd64)
• Debian 10.13 (4.19.0-23-amd64)
   

 
Step 1:

sudo nano /etc/apt/sources.list

deb http://deb.debian.org/debian/ bullseye main contrib
deb-src http://deb.debian.org/debian/ bullseye main contrib
deb http://security.debian.org/debian-security bullseye-security main contrib
deb-src http://security.debian.org/debian-security bullseye-security main contrib
deb http://deb.debian.org/debian/ bullseye-updates main contrib
deb-src http://deb.debian.org/debian/ bullseye-updates main contrib

Step 2:

sudo apt-get -y --no-install-recommends install \
      make g++ git \
      python3 swig python3-dev libreadline-dev \
      libsdl2-dev libsdl2-ttf-dev \
      gettext imagemagick inkscape \
      libmosquitto-dev \
      libmpdclient-dev \
      gcc-avr avr-libc

git clone https://github.com/gkiefer/home2l

cd home2l

Step 3:

make CFG=basic

mqtt.birthAndWill not updated during long-term interface failure

If the bus connection gets lost and recovering isn't successful, the mqtt.birthAndWill topic is not updated and stays in online state.
The brownie device status topics are correctly set to ?, during the connection lost.
If I manually stop the home2l-server, the mqtt.birthAndWill topic gets the correct offline value.
I use the latest home2l release with an ELV USB-I2C adapter on amd64 hardware with Debian 11.

home2l.conf:
mqtt.birthAndWill = status:offline:online
