Hello Fabio,

You can select the EMO-R8 module to expand the Unipi 1.1 board with another 8 relays. This module communicates via I2C, as does the relay on the Unipi 1.1 board. Documentation for this module can be found on our KnowledgeBase.

For communication, you can choose either direct control via I2C, or use our EVOK API, which allows you to control, for example, via the REST API or WebSocket.

EMO-R8 connection and EVOK configuration:

You must first set the address jumpers on the EMO-R8 and connect to Unipi 1.1 using an I2C cable. Then connect the power supplies, connect to the Unipi unit via SSH and edit the /etc/evoc.conf file. Then restart EVOK and the outputs on the EMO-R8 will be available.

In the /etc/evok.conf file, find the lines related to EMO-R8 and uncomment them (remove the semicolons at the beginning of the lines). Open file with administrator privileges (sudo). sudo mc -e /etc/evok.conf Then restart EVOK. sudo systemctl restart evok.service

Best regards,
Antonin

Hello @FabioIT,
can you please share the wiring diagram and the jumper settings?

Thanks,

Hello @FabioIT, we have updated the tutorial on measuring the resistance: https://kb.unipi.technology/en:automation:02-glossary:analog-inputs-hidden#measuring_resistance

Hello @FabioIT,
the SPI is not used by the Unipi 1.1 and it is not exposed as any port. You can access the SPI on the pin header of the Raspberry Pi, but it would require to create some "hat" that goes between the Rpi and the Unipi 1.1 ribbon connector.

Hello @fabioit,
the time and date is managed by the timesyncd service. To set the timezone and disable the NTP use the timedatectl:
