I recently added fairly aggressive REFRESH commands to a Z-wave light switch to work around its slow polling interval for controlling a set of LiFX lights. This solves the slow response problem, but its cluttering my event log with entries like the following:
2018-01-06 10:23:02.025 [ome.event.ItemCommandEvent] - Item ‘Living_Room_Light_Switch’ received command REFRESH
I don’t really need to see REFRESH commands in the event log, but I can’t figure out if its possible to filter them out. Is there any way to do this?
specifically, I modified org.ops4j.pax.logging.cfg (which is located in different places depending on your OS) and added this to the end. I can’t recall if the modifications I made earlier in the file were necessary to activate logging this to a different file (in my case, zwave.log wherever openhab.log usually resides):
Do you mind elaborating a bit on the use of REFRESH commands (especially in the context o Z-Wave devices). I was not aware that such a command existed…
Sure, although I worked around it by changing the device in question. The use case was a GE z-wave dimmer switch that didn’t necessarily report the dimmer state immediately to the controller. I didn’t have it directly controlling the lights, I was using its setting and set setting the (Always on, Wifi controlled) lights based on that setting. By sending a frequent refresh, I could update the light state from OpenHab, rather than waiting on the switch to send its state which would take minutes and was useless.
I abandoned the dimmer switch in favor of an on/off switch that instantly updated state, and I controller dimming via OpenHAB, the LiFX app or Alexa instead.
OK, then I understand your use case. I don’t fully understand how the REFRESH command works, though.
I assume that the ‘Living_Room_Light_Switch’-item in your original post is supposed to be updated when someone operates the physical switch, right? As I understand it, this did not happen as quickly as you wanted (immediately), and you could solve (or rather, work around) this by sending a REFRESH command to the item to “force” the device to update the item/channel. Is this correct?
In my setup, all my Z-Wave switches/dimmers seem to send immediate updates (as they should IMO!) when someone is operating them, however, when I restart my openHAB server it may take quite some time for the system to get a correct state of the switches - unless someone happens to operate them.
I suppose this could be a case for using the REFRESH command, i.e. at “System started”. What do you think?
