@timo Looks like new binding no more support reporting of battery voltage from sensors, or I missed something?

@andreacioni All mySensors item defined using auto-discovery, so no things file in configuration. I'm think you mean this file? 0_1506175698221_org.eclipse.smarthome.core.thing.Thing.json

@TimO just updated to version 2.2.0.201708090807 of binding and get exception in network check

Hmm, for some reason link to code does not working, so, if anybody interested, here on github:
link text

@anonymouslemming Hmm, you wish to use existing switch on mains cord? Or have some socket block with control is enough? I have use old one-for-all remote-controller socket for that - it have button, place for LED, nice case and i put inside arduino pro mini and 5 volt supply, using existing relay.

You are from Great Britain, right? So you have different power socket, but, may be you can find something similar?

@anonymouslemming Sorry for self-advertising, but i'm think my project https://forum.mysensors.org/topic/7417/ikea-varv-lamp-and-mysensors exactly what you wish - lamp with local control and, of course, OpenHab status automatically updated on flick a switch.

Hello!
Let me introduce simple project - MySensors control for IKEA Varv lamp. http://www.ikea.com/us/en/catalog/products/70280709/
Used hardware:

• Arduino Pro Mini 5v
• nrf24L01+ module
• solid state relay https://www.aliexpress.com/item/5v-1-Channel-OMRON-SSR-G3MB-202P-Solid-State-Relay-Module/32545508200.html
• 5V to 3.3V converter based on LM1117 https://www.aliexpress.com/item/LM1117-AMS1117-4-5-7V-turn-3-3V-DC-DC-Step-down-Power-Supply-Module-For/32588261370.html
• piece of prototype board, wires, etc

Disassemble lamp: remove shade, disassemble bulb holder to get access to switch and wiring, remove cover from base (note four screws hidden under rubber pads)

and get access to internals

Remove mains wires from switch, connect it directly to lamp bulb holder, connect additional wires to switch to use it wits MySensors and route new wires throw pipe stand to bottom part

Open cover of usb charger (be careful and do not damage the board)

solder wires for powering arduino to usb ground and +5v

Connection between nrf24L01+ and arduino pretty standard, i use piece of prototyping board to hold radio module and voltage converter together. This sub-assembly and arduino pro mini fits perfectly into base of lamp, just cut a little for wires pass freely.

Relay module little modified to fit into lamp base - relay de-soldered, pins bend to 90 degree and relay soldered from other side of board, terminals for control signals replaced with pin connectors.

Relay connected to arduino pin 3, switch to pin 4 .
Because this project should have a wife compatibility mode :) switch was used not as on/off switch, but as a trigger, lamp switch state on switch change, not on switch position.

Comments and suggestion is welkomed, and sorry for my not-so-good English.

Successfully used over a week in my home, using OpenHab2 and ethernet gateway.

@rob I have similar problems caused by unstable radio link. Long debug and playing with position of gateway and sensors in apartment, radio channel, etc resolved it, but it can be very frustrating. I recommend from my experience try to reduce distance between gateway and sensor and use MYScontroller as debug tool. Once you have stable sensor network openhab plugin start working like a charm.

As far as I understand, mysensor and openhab plugin works like this (timo, correct me if I wrong)
1: sensor establish link to gateway.
2: sensor request node ID from gateway.
3: plugin generate node ID and send it via gateway to sensor
4: if sensor with nodeID not defined aready in plugin config, sensor added to detected inbox

Looks like your setup stopped somewhere on step 3, but as check I recommend use myscontroller as independent verification

@rob
As I see from log, gateway unable to send to sensor 5 response to find parent

I recommend to debug your radio link, may be using MYSController

Hello @TimO !
I delete all things and items (btw, seems like items not deleted completely, and re-apperas after item re-create), create things again and not see error anymore. Some black magic in action, looks like.
I will create separate topic if this issue appears again. Thank you!

Hello!
I just started to play with OpenHab2 and new binding? thank you for great work.
But, i discover some strange behavior:
Openhab2, ethernet gateway, 3 mysensor nodes, all nodes sucessfully detected and configured in PaperUI, but some data looks like not updated. Looking to log i note some suspicious lines like:

00:28:47.077 [DEBUG] [rsAbstractConnection$MySensorsReader] - 3;1;1;0;0;24.6
00:28:47.078 [DEBUG] [rs.internal.gateway.MySensorsGateway] - Node 3 found in gateway
00:28:47.078 [DEBUG] [rs.internal.gateway.MySensorsGateway] - Child 1 found in node 3
00:28:47.078 [WARN ] [rs.internal.gateway.MySensorsGateway] - Variable 0 not present

Sorry, i don't know how to dump OpenHab configuration, but item configured.
Any suggestions?

@Chaotic I can answer second question - you can power radio from on-board 3.3V regulator from Uno or Leonardo. I use this setup without any problems.
First question - not complete understand it. If you manage assign node ID to sensor (using gateway or manually edit EEPROM) - sensor node can operate without controller/gateway

@hek Accordingly to LowPower library documentation, library support Atmega32U4 processor, so should work on Leonardo.
Look's like i need to investigate deeper.

@doctor64
Just note if anybody try to test: after the bug it is unable to upload new sketches until reset - disconnect your Leonardo from USB, close Arduino GUI, reconnect Leonardo and start Arduino GUI

Hello!

I try to use Leonardo for my sensor development and encounter strange problem:
Sensor successfully initialized, perform first loop, and after entering sleep() never come back, TX LED on Leonardo constantly lights.
Anybody have an idea? Replacing sleep() with delay() solves the problem, but i fear what sensor can lost packets from gateway during sleep.

Arduino 1.6.0, MySensors library 1.4.1
demo code
https://codebender.cc/sketch:87221

into sleep

@samppa Sorry, i am not familiar with Vera and PLEG. As last resort, you can use OpenHab with Vera - i'm think Vera is ZWave controller?

@PedroC88 Sorry, i not completely understand your requirements. Do you want a sensor which generate signal when somebody walk near the car? You can look at PIR sensors, but i am not sure can they work outside a building.

@samppa Seems like high humidity in bathroom is a common problem, because i also plan to implement exactly this thing.
But, because i can't pump fresh air from outside, i live in multi apartment building, so i pump humid air from bathroom into existing ventilation system.
I think about just add second sensor to same node and check humidity in corridor, or may be use "dumb" node, there all calculations and decision about turning on/off the fan made at controller, OpenHab in my case. So i can take into account time of day, for example - i don't want to hear noise from the fan in the middle of night.

@samppa There is a article (in Russian, unfortunately) where solved almost exactly this problem. (Ventilation of garage)
http://habrahabr.ru/post/244135/
If you wish i can try to translate, but basic idea of algorithm is to calculate absolute humidity for inside and outside, compare and turn ventilation if inside absolutely humidity bigger than outside with threshold 0.01 gram/m3. Also, if outside relative humidity is large than 90% ventilation does not performed, because it happen in very unusual case, like heavy rain outside, and ventilation in this case is pointless.

@hek I can confirm what MQTT gateway working good (with some troubles, but none too seriously) on version 1.4.1 using SOFT_SPI and Wiznet W5100 module (common Ethernet shield).
