I've got this weird issue concerning a blockly event. This blockly doesn't do anything at all. It concerns this blockly:

The PIR is an Xiaomi motion sensor, which reacts normally to movement in domoticz. The light is an Yeelight RGBW bulb, which also reacts normally to commands in domoticz. Nevertheless, in blockly it doesn't do anything... The weird thing is that I have multiple, far more complicated, Blockly's running for years.
Is there something wrong with the command to the lightbulb? Or something with the Xiaomi sensor?
