Hello,
This work for me on OH3.2.
@vores8 said in https://forum.mysensors.org/post/110626:
i've managed to build new version from the sources found here https://github.com/nikolac/openhab-addons/tree/mysensors-oh3-migration
So far, so good - working with the latest OH 3.1.0
please download from https://disk.yandex.ru/d/Yq3gn8N7tXSQxA
At first I'm no expert of MySensors or openHAB.
Perhaps I had luck but got the connection between MySensors and OH to work from
the beginning with only minor problems. The system has now been working for almost 2 years and I did it this way.
OH is installed on a RPi 3B, have a serial gateway on an Arduino Nano with nrf24L01 pa+lna the nodes (5 pcs) are built on Arduino pro mini.
The nodes are 3 Door/Window sensors, one relay and one tempereture/humidity sensor.
Since the gateway is placed in the basement and the nodes are on first floor one of the nodes is using nrf24L01 pa+lna and the other nrf24L01+.
The nrf24L01+ are chines and I bought about 15 of them and tested them at a distance of 12m through 2 wooden walls and have to scrap 3 of them.
The gateway and nodes have all standard sketches according to MySensors examples with minor changes. All nodes have fixed node_id.
Installation:
Downloaded "openHABianPi" SD card image file.
Wrote the image to a SD card and put it in the RPi.
Started the RPi and after some minutes OH was up and running.
Complete insructions can be found at https://www.openhab.org/v2.4/docs/installation/openhabian.html.
Connected the gateway to OH via a USB cable.
Went to MySensors/Controller/openHAB and followed the "Install instructions" at https://github.com/tobof/openhab2-addons/wiki.
Used Paper UI to configure the thing "MySensors serial gateway" and not .things file.
Now the nodes (things) pop up in the Inbox. Don't remember if I had to restart the RPi, gateway and nodes.
I hope this can help someone.
@masmat No it's not necessary to put the "Contact" in a sitemap, your arduino shall send boolean (0/1).
@gohan Thanks for your reply, you can show me how the code should look.
I am a newbie and have some thoughts about the battery level that I did not find in this forum.
The 8MHz 3.3V Arduino Pro Mini can handle down to roughly 2.8V.
If I have understood the calculations in the sketch correctly then the analog value of A0 is 1023 at 3.44V and 0 at 0V.
This means that at 2.8V the value is about 830 = 83% and under this, the Arduino stops working. Is this right?
If this is correct, I wonder if someone has changed the calculation in the sketch so that the battery percentage becomes 0 at 2.8V?
This would mean that the battery percentage becomes a more real value on the battery level.
I have a battery operated node with a door switch using sleep and no debouncer.
The node seem to work well but I have some thoughts about reliably in my sketch.
The first 2 lines in the "void loop()" is:
wait(50); // Short delay to allow switch to properly settle
value = digitalRead(BUTTON_PIN);
and the last is:
sleep(digitalPinToInterrupt(BUTTON_PIN), CHANGE, SLEEP_TIME);.
As I have understand, when the door e.g. is opened during sleep time the arduino wakes up and starts the loop from the beginning, is this correct?
If so, will "wait (50)" prevent "bouncing"?
Perhaps not the best solution but easy for a beginner.
It's possible to use "Win32 Disk Imager" to make an image of the a RPi SD card and save on e.g. Windows PC. Explained here: https://computers.tutsplus.com/articles/how-to-clone-your-raspberry-pi-sd-cards-with-windows--mac-59294
If you make an image, e.g. after changes in openHAB or at selected times, can't this be used to restore the system?
I'm aware of that data colected since the last made image will be lost and the system is down during the process.
@dbemowsk I'm have just started with mysensors and have configured a soil moisture sensor together with openHAB.
To get it to work I used the sketch for soil moisture but present the child as S_HUM and send the reading as V_HUM.
@rozpruwacz Thanks!
That it could be that simple! 
Did not see the connection between sending the battery status in the sketch and the thing in openhab.
I started a few months ago with MySensor and openhab and have now configured a node with a door contact. I'm using a serial gateway connected to a RPi with openhab. The node is registered as Door in openhab and works with the door Open / Closed. The node is powered by battery so I want to report battery status but do not know how to get this to openhab. Have searched the forum but have not found anything.
The Thing Door has in openhab 4 channels:
Tripped Status, mysensors:door 709db93f:door_3_1:tripped, Contact
Armed Status, mysensors:door 709db93f:door_3_1:armed, Switch
Battery Level, mysensors:door 709db93f:door_3_1:battery, Number
Last Update, mysensors:door 709db93f:door_3_1:lastupdate, DateTime
All the channels have the same node id (3) and child id (1) so how shall I send the battey value from the sketch to the channel "Battery Level"?
@sundberg84
I read in another topic your reference to https://www.arduino.cc/en/Tutorial/ArduinoISP on how to burn a bootloader.
Is this an opportunity to get the wrong card to work?
Do you know if the capacitor mentioned in the reference is needed for a Pro Mini?
I have programmed 3 more boards with the first settings and it worked well.
What I understood, only the choice of programmers is used when burning bootloaders, is this correct?
The problem is partially resolved, the first Pro mini is wrong in any way.
Tried another Pro mini and it worked.
Before I switched the minis, I searched the Arduino forum and found this topic on how to test a serial adapter and according to this test the FTDI adapter was ok.
https://forum.arduino.cc/index.php?topic=73748.0
After switching to Ide 1.8.3 and even when I switch back to 1.8.0 and I choose sketch, include library, manage library I get the following error message:
Index error: could not find referenced tool name=gcc-arm-none-eabi version=5_2-2015q4 packager=sandeepmistry
Index error: could not find referenced tool name=openocd version=0.10.0-dev.nrf5 packager=sandeepmistry
Is there something to care about?
I have updated ide to 1.8.3 but the result is the same. Find no way to update boards difinations.
I missed one row in the error message which I think is important:
"avrdude: stk500_recv(): programmer is not responding"
I have purchased some pro mini 5V and an USB to TTL programmer, from china.
I have connect them occording to the following:
Programmer Pro mini
DTR>>>>>>>>>DTR
TX>>>>>>>>>>RX
RX>>>>>>>>>>TX
VCC>>>>>>>>>VCC
CTS>>>>>>>>>-
GND>>>>>>>>>GND
Arduino IDE 1.8.0
Board: "Arduino pro or pro mini"
Processor: "ATmega328 (5V 16MHz)"
Port: "COM6"
Programmer: "AVRISP mk II"
When I try to upload the sketch "Blink" I got the following message:
avrude: verification error, content mismatch
0xff != 0x0c
avrude: verification error, content mismatch
avrude: verification error; content mismatch
Anyone who can tell me what the error is?
@Feji
Thanks for your replay! But unfortunately, that was not an answer to my thoughts.
@TimO
I'm new to MySensors and openHAB and this might be vary basic questions.
As I only have start with a small system with openHAB on an RPi3, a serial gateway and 2 nodes so the update to openHAB 2.2 binding will probably not be a big deal.
In the explanation of the changes, you write "The current release is not backwards compatible" and "I hope this won't happen again in further versions!". Does this mean that a new version is backward compatible with e.g. V2.1.0 or that I in anyway must do the reconfigurations now but don't have to do it again?
I have configured my things in Paper UI and have to delete them but do I have to clean the *.items file and *.sitemap file? Further down in the "topic" you have a link to "https://github.com/tobof/openhab2-addons/issues/86" with a link to a new version of the binding and I wonder if this is the one I'm going to use?
@kalina I'm new to "MySensors" and I think this device will suits me very well. My plan is to use MQTT and Wi-Fi mode.
Is this possible? To use Wi-Fi / Ethernet, as I understand, IP addresses for Gateway, router and controller must be defined but I have read that you in all modes is using the serial gateway sketch which not have IP adresses defined.
I wonder if there is any other gateway sketch that shall be used or how to solve this?
Hi @Tommas
A new try. In your definition of the item airq01 you have in the channel="mysensors:airquality..." written "q" in lowercase letter.
When I look in MySensors Binding in Paper UI it is written with a capital "Q", "airQuality". I don't know if it matters.
Hey @Tommas
What happens if you in the sitemap change "Defult item=airq01" to "Text item=airq01"
I'm a newbie and have just started a project to control things in my home.
To learn, I have set up OH2 on a raspberry pi 3, using an Arduino nano as serial gateway and two nodes.
Everything works well. Now I have read here in the forum about MQTT which many seem to use but not found when or why to use it.
Hope anyone can explain the benefits of the two methods.
Are there situations when MQTT has to be used?
If using a MQTTgateway, as described in MS, do I have to have a MQTT Broker e.g. on a RPi?
This tip may already be known.
I have an Arduino uno and an breadbord to make tests of new projects but got tired
of to have the radio "nRF24L01+" hanging loose in the wires.
I then find that there was an adapter to the ESP8266-01, "WiFi Module", to be used
on an breadboard. The pin configuration is wrong so I put a label on the adapter
and numbered the pins in accordance with nRF24L01+, pic 1. I also have to desolder the
capacitor on the adapter, pic 2, this could be of diiferent kinds and other places.
And now the radio fits on the breadboard!
