Apparently, after so many years, Philips still believes that you only need a sensor to switch either during the day or at night. For example, if you only want to switch your lamp with the sensor in the evening and in the morning and not during the day and at night, then you are in for the effort because then you have to be able to set 4 periods and that is not possible.
In addition, the sensor switches off your lamp, even if you set it to do nothing for a certain period. The setting 'do nothing' therefore only applies to switching on. He does turn it off. So, for example, if you have set the automation for a lamp to burn continuously from 20 to 23 hours and then only via the sensor, then you can also forget about it, the sensor switches that lamp off again between 20 and 23 hours, even if you choose the 'do nothing' settings.
Fortunately, the sensor is compatible with Homekit. So I completely removed it in the Hue app and made all settings with the Home app. If not, he would have returned without delay.
Conclusion. If 2 settings are enough, this is a great sensor. If not, it is best to ignore it if you do not have another smart home platform.
