Domoticz/RFXtrx433E Event ('Blocky') Not Turning Off

[knotty]

Hi,

I've instaled a LightwaveRF door sensor on the garden gate of our house and fairy lights in the garden bar connected to an Energenie 4 way extension lead (ENER010). I've created a Domoticz event (aka 'blocky') (attached) so that if the kitchen patio door opens then the bar lights turn on for 1 minute. The lights successfully turn on when the door opens however they don't turn off, either when the door is closed or left open.

Any thoughts/ideas? Thanks.

Regards,
Paul.
