I’ve had a number of these relays installed and functioning correctly for over a year now. In the past week, the one controlling my driveway lights has stopped turning the lights on (they do turn off properly) when a lux rule instructs.
In the logs I can see the rule sending the “on” command then the relay returns “dev:259 2022-01-18 17:02:29.722 gParse returned null”. This same message appears when manually turning the lights on or off and they function properly.
I haven’t made any changes to the system in at least a month and the lights turn off/on flawlessly from the “device” page in the Hubitat control panel and from a dashboard.
If somebody can provide direction on what to check next for troubleshooting, I will be appreciative.
