yml files
Entry sharing
If the values should be reused yml features anchors
with &
which then can be referenced with *
. This allows to reuse the defined structures:
my_key_value_pairs: &my_kv # <-- this creates the anchor node with the name my_kv
4: 99 # Light Threshold
5: 8 # Operation Mode
7: 20 # Customer Function
value_1: *my_kv # <-- '*my_kv' references the anchor node my_kv
value_2: *my_kv
value_3:
<<: *my_kv # <-- '<<: *my_kv' references and inserts the content (!) of the anchor node my_kv
4: 80 # and then overwrites parameter 4
openHAB
autoupdate
If external devices are capable of reporting their state (e.g. Z-Wave) it is always advised to use disable autoupdate
for these items.
This prevents openHAB from guessing the item state based on the command and forces it to use the actual reported value.
If in doubt if the device supports reporting their state it can be easily tested:
Set autoupdate
to off, then watch the item state after sending a command to it.
If the state changes autoupdate
can remain off.
In the *.items
file autoupdate
can be disabled by adding the following statement in the metadata field.
Number MyItem { channel = "zwave:my_zwave_link", autoupdate="false" }
It’s also possible with textual thing configuration to add it as metadata.
