Tried to set invalid state 0 (DecimalType) on item Lights [...] ignoring it

Setup, Configuration and Use Items & Sitemaps

I faced the same issue and was wondering what the reason could be and I discovered that the label formatting of the item is causing an issue. Look at the code above from post #1. The switch status is either ON, OF for a contact OPEN, CLOSED. These values are handled as strings but the formatting says %d which is decimal. This is a type mismatch and that’s causing the issue at least it was the solution in my case to change the formatting to s%.

Note that you can use %d with Switch type groups, but it may not do what you expect - it provides a count of active members.

Hi rossko57,

thanks. I know you can get a count of items but in my case it caused issues.

Well I’ve used %d and it caused the following error:

Tried to set invalid state 1.0 (DecimalType) on item gTasterOUT of type SwitchItem, ignoring it

But the items config was:

Group:Switch:OR(ON, OFF)	gTaster			"Switch Illum. [%d]"		(gScene)
Group:Switch:OR(ON, OFF)	gTasterOUT		"Switch Illum. Out [%d]"	(All)
Switch	Taster_Garage		(gTaster,gTasterOUT)	{ knx="4/6/0" }

After changing the format to %s the error disappeared. I got the error message always on startup.
hth,
