| Everyone who has become infected with the topic of smart home considers almost continuously how he/she can still automate manual, recurring tasks further. Provided that the appropriate sensors and actuators are already available. A sensor area that seems somewhat underrepresented is the occupancy sensor, e.g. to trigger or refrain from actions by going to bed. \\ | Everyone who has become infected with the topic of smart home considers almost continuously how he/she can still automate manual, recurring tasks further.

| - | There are alarm mats as bed rugs or professional bed sensors from the care sector. The seat sensors from the automotive industry also perform a similar task. What they all have in common, however, is the lack of connection to an open protocol such as MQTT and of course the usually very high purchase costs. | + | There are alarm mats as bed rugs or professional bed sensors from the care sector.

| Both values are read out every second and if there has been a change to the threshold value, the result is sent to the MQTT server. These are the states IN and OUT. You can of course also transmit the current values and leave the decision as to whether IN or OUT to the home automation. In the following example I recorded a night like this. | Both values are read out every second and if there has been a change to the threshold value, the result is sent to the MQTT server.
