    Hi!

    Say I want to create a node that turns everything off when I fall asleep.
    One option would be to use a heart rate / pulse sensor and when it goes below a certain amount, run the turn off action - but that will require me to wear the sensor.
    Another (less accurate option) would be to know when I lay down on the bed, and after a certain predefined time - run the turn off action.

    Another scenario is that I want to know when there's new mail in the mailbox.

    For this - I need a weight sensor node that can sense the weight change of the mattress or that there's new mail on the sensor in the mailbox.

    I can't, however, find such a sensor. All I can find is a pressure sensor which seems to be barometric + temperature sensor...

    Anyone knows of a weight sensor I can use for this node?

    Thanks!

          Put this underneath your mattress. It's a pressure sensor, add Mysensors door/window sketch, add timer to your homecontroller and switch off after timer runs out

            Will that work as a weight sensor?
            Couldn't understand from the description nor could I find the data sheet...

              Think you have to use it in combination with a sensor block like this.

                Hi @hek ,

                thanks for your answer. Unfortunately, this will not work for this application...

                  @Sefi-Ninio I was checking out MySensors videos on youtube one day and I stumbled on this one.
                  Cheap Bed Occupancy Sensor using Arduino & MySensors
                  I think this concept is exactly what you are looking for. I have thought about building this one myself.
