@robski Yes it happens only when relay is called to be on not in standby
Unit 4relay is connected to Port A with his supply(5V), but I using +24vdc for supplied m5dial

Hello I have m5dial and connected to port A Unit 4Relay
When I download program to m5dial with Unit 4Relay its works okay, but sometimes when relay turn (no matter what) I get this error in m5dial

When I burn m5dial to V 2.4.2i get this error(5x per hour) so it was worst then V 2.3.6 (1x per day)

Can someone help me with this pls?

@felmue
Oh ok i thought it was similar to m5core2 sorry my mistake.
anyway with m5core i used 4 relays via i2c.

How to set i2c to work in m5dial?
I can't program in python, so if it could be explained in blocks in uiflow?
I need to program 1 inputs and 3 relays
Thank you

@felmue

When I do it like this, it doesn't turn on

Hello, how can i turn on m5dial with external 12voltage without using USB C and board? If it has to be in the program, please do it in Blocks in uiflow
