Hello,

The I2C port is permanently connected to 5V and cannot be changed.
For the UART port, it is possible to change between 5V and 3.3V using a jumper (JP6).

Best regards,

It is a problem related to power-supply.
It was some voltage peaks while connecting anything to the same circuit as power-supply.
I've a better one (Phoenix Contact) and it's working stable now.

ok, thx:)

ok, thx for feedback

@Martin-Kudláček Do you maybe know how i can check current speed of I2C, which is set over device tree overlays?

Thx for explanation!

Hello @mglowinski,
the Evok doesn't have such logic. If the DI doesn't support counters (which does not on Unipi 1.1), the Evok is not able to share this information. This has to be done in your software.

Best regards,

To make extension relay module (EMO-R8) working with EVOK below steps needs to be done:

Open /etc/evok.conf file Uncomment relays assigned to EMO-R8:

Each this line begins with a character ;
This character must be removed for all lines related to the configuration for EMO-R8:

; ;Example of 8xRelay extension module addon (EMO-R8) on address 0x21 ; [MCP_2] i2cbus = 1 address = 0x21 [RELAY_9] mcp = 2 pin = 7 [RELAY_10] mcp = 2 pin = 6 [RELAY_11] mcp = 2 pin = 5 [RELAY_12] mcp = 2 pin = 4 [RELAY_13] mcp = 2 pin = 3 [RELAY_14] mcp = 2 pin = 2 [RELAY_15] mcp = 2 pin = 1 [RELAY_16] mcp = 2 pin = 0 Save /etc/evok.conf file Restart evok

Hello @mglowinski,

sorry, but this feature is not supported in Unipi 1.1 series products. Please consider buying Neuron/Patron series PLCs which can do it.

I made it work.
I enabled Serial in RaspberryPi Setting and and used /dev/serial0 and it worked.

Thx @martin_triska for help!

@martin_triska,
thx for a tip. Indeed it worked quite well:)
