Hi Ronny,
Thnx for your reply, I have the modbus working an hour ago.
The problem was in my tags in the Jmobile software.
What would be the fastest way when i hit a button on my HMI that homey starts a flow?
Modbus can only be polled.
You can create a flow with a time based trigger (every xx seconds). Then read the Modbus register and use logic cards to check the value. Then you can use action cards to do something.
If you want to react on a change, you can create variables to remember a register state. Set the variable in your modbus flow.
Then I suggest to create a second flow to react on the “variable changed” trigger to do something.
Are you inside a “standard” flow? You have to use AdvancedFlow to combine several flow cards in a line to use the read value in the next card(s).
