PaPiRus-MQTT

MQTT Dashboard utilizing an ePaper / eInk Display on a Raspberry Pi (i prefer the Raspberry Pi Zero W, because i only need one cable)

First, install the driver, install all necessary stuff and papirus-mqtt.py to /home/pi

Setup PaPiRus and PaPiRus-MQTT

curl -sSL https://ci8.de/papirus-mqtt | sudo bash

Select your screen size

For the Papirus Zero, there are two sizes at the moment

Execute the following to set the screen resolution.

sudo papirus-set [1.44 | 1.9 | 2.0 | 2.6 | 2.7 ]

or

sudo papirus-config

Troubleshooting

papirus-set and papirus-config are useful, when you want to fix issues with the driver on a previously working raspian installation.
run papirus-config disable the driver, papirus-set with the correct resolution and then reactivate the driver in papirus-config.

OpenHAB Items

I use OpenHAB to push Data to my MQTT Broker
Those items have i created for it (once they receive an update, it will be sent to the MQTT Broker)
I recommend to Push the Data not to often, but at least once a minute (correct time on screen)

Group       e_paper         "E Paper Display Items"
