After C7-hub last update my Rule Machine became useless. None of the rules are triggered, though clicking on "Run actions" inside the rules window is correctly triggering the rule.
What I did in order to fix this:
deleted all the rules and recreated them - doesn't helped
removed and reinstalled Rule Machine - doesn't helped
This is the error sequence I get with a specific rule which should start dimming a light bulb (IKEA Trådfri) at a specific time:
java.lang.NumberFormatException: For input string: "1.1" on line 5013 (updated)
java.lang.NumberFormatException: For input string: "1.1" on line 5013 (appButtonHandler)
