Unable to transform NULL using transformation map {"OFF":false,"ON":true,"CLOSED":false,"OPEN":true}) #31

Hi, I noticed a few times in the log file that the plugin receives NULL value from OpenHub which causes transformation error and the accessory in Homekit become in error state: [6/24/2019, 4:30:12 PM] [openHAB2-Complete] Received state: NULL (transformed to Error: Unable to transform NULL using transformation map {"OFF":false,"ON":true,"CLOSED":false,"OPEN":true}) for Nilan Filters Replace [HomeKitVentilationFilterItem] [6/24/2019, 4:30:12 PM] [openHAB2-Complete] Unable to transform NULL using transformation map {"OFF":false,"ON":true,"CLOSED":false,"OPEN":true}

One strange thing is, in the events.log of OpenHAB the state of the switch in question has never been set to NULL. How to diagnose problem like this? Thank you!

In general you could enable the homebridge debug log and see if there is a cache miss and a problem with this plugin. Otherwise this also might be an openHAB issue, where you can use the openhab console to check the actual system state.

Thanks! I think it's OpenHAB issue, because the values are updated rarely and the cache was reset for some reason. Now I added a condition in my rules to trigger every 15mins the issue is gone :)
