    • RE: wireless door / window sensor

      If you need a signal both if the window was closed and opened you can buy this sensor:
      https://www.aliexpress.com/item/Free-shipping-Wireless-window-and-door-magnetic-sensor-open-detector-1527-chips/32334214010.html
      It is based on a 1527 Chip.
      Open the rear cover and connect these pins with a solder point:

    • RE: How to know the node ids assigned by the mqtt gateway to the sensors?

      @amitach I have the same setup and I use a MQTT-Client for testing: http://www.jensd.de/wordpress/
      You have to stop OpenHAB, because only one connection to the gateway is possible.
      Usage:

      • start client
      • create a profile: Extras / Connection Profiles
      • connect with this profile
      • click button "Subscribe"
      • choose "Topic" : # (see wildcards: http://mosquitto.org/man/mqtt-7.html )
      • click button "Subscribe" (on the right from field "Topic"

      Now you see all messages from your sensor.

      10-10-0-0
       |  | | |
       |  | | Id of Destination node
       |  | ID of next node
       |  Id of last node this message passed
       Id of sender node (origin)
      
      
      s = child-sensor-id, 255 für "interne" Messages
      c = message-type
      t = sub-type
      pt = payload-type (see MyMessage.h)
      l = length of payload
      

      Values c,t,pt: see http://www.mysensors.org/download/serial_api_13

    • RE: Data from MQTT Gateway not pushing to OpenHab

      @Jransom2 Unless I'm very much mistaken there is no temperatur message in the lines after "Started!".
      During the last day several users of OpenHAB / MQTT had a problem with the first connection. A good tool for debugging is the MQTT client from jerady.
      See my posting here: http://forum.mysensors.org/topic/953/how-to-know-the-node-ids-assigned-by-the-mqtt-gateway-to-the-sensors/

    • RE: In wall light switch node - Custom PCB

      For more than two switches see: http://www.gammon.com.au/forum/?id=11091
      I would add a hardware debouncing (R/C) to avoid the problems mentioned in the article.
