- Issue of the topic: Number Item state shall be set from the result of a file
I would like to set the state of a number item in a rule by executeCommand.
The command reads a value from a file (which is 0 or 1) and shall post it to the item.
I already rewrite the executeCommand to be runnable on OH4 (I came from OH2 where all works fine).
This is the code:
val VdfSt = (executeCommandLine(Duration.ofSeconds(10),“//bin/cat”,“//run/openhab/net.vdf”))
That produces the following log:
“2023-08-12 03:35:05.493 [WARN ] [b.core.model.script.actions.BusEvent] - Cannot convert '0
’ to a command type which item ‘VDFONL’ accepts: [DecimalType, QuantityType, RefreshType].”
When I do:
VDFONL.postUpdate(VdfSt as DecimalType)
“2023-08-12 03:38:45.337 [ERROR] [internal.handler.ScriptActionHandler] - Script execution of rule with UID ‘net-1’ failed: Could not cast 0
to org.openhab.core.library.types.DecimalType; line 7, column 20, length 20 in net”
Could someone help me what the correct coding would be?
