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.

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.

RE: Double channel lora Gateway (UP/DOWN)
@alexsh1 Sorry you missunderstood. My post was only a hint to help riro2 with his LORA problem. The Libraries from the refered project are working fine for me. Thanks anyway!

RE: Double channel lora Gateway (UP/DOWN)
I'm experementing with this Library / Project:
http://cpham.perso.univ-pau.fr/LORA/RPIgateway.html
https://github.com/CongducPham/LowCostLoRaGw
based on the Libelium Libraries.
It is LORA-only (no LARAWAN). Thanks to the used arduPi-Libs there are the same soures for Arduino and Raspi.
Originally only sensors are supported. I have changed the sources a bit to support both directions but with ONE Lora module. It shouldn't be difficult to use two modules. -

RE: Trouble sending message to Relay from Openhab
Is there a Serial.begin in your Arduino Code?

RE: Good-looking way to control dimmer?
Yes, you need something to turn or to press. I would realize this with 2 parts: A MySensors device as "sensor" at the wall and another MySensors device as "actor" near the dimmer which controls the dimmer. Benefits: a better energy efficiency; no deal with 230V; ability to integrate a "controller software" like OpenHAB for further possibilities.

RE: Good-looking way to control dimmer?
I wood choose a power supply with a PWM Dimm Input. Then you have only to handle with low Voltage (10V). To control the power supply you only need an arduino and an optocopler.
MeanWell Power Supplys: http://www.trcelectronics.com/Meanwell/power-supply-led-dimmable.shtml
You have to choose one with the required power and with "constant voltage". The Aliexpess Part is a constant voltage supply too - I think. Chinese Sellers often don't know what they sell! -
RE: battery level doesn't appear ?
"Battery Level" is a internal message.
See: http://www.mysensors.org/download/serial_api_15
This means it is going to the gateway and nobody knows what the gateway is doing with it...
Please correct me if I am wrong. -
RE: Openhab issue: Error during the execution of rule 'Arduino sends to Openhab': 5
I have not checked your code. But opening "{" and closing "}" brackets should have the same count.

RE: Adding a light switch to Openhab/MQTT gateway
Hello,
I'm using exact the same statement. In addition I have a mapping statement. Don't ask if this is necessary.
My line:
{mqtt=">[mysensor:MyMQTT/1/1/V_LIGHT:command:ON:1],>[mysensor:MyMQTT/1/1/V_LIGHT:command:OFF:0],<[mysensor:MyMQTT/1/1/V_LIGHT:command:MAP(1on0off.map)]"}The content of file 1on0off.map in folder /configurations/transform:
1=ON
0=OFF
