Today I completed the installation of the first of my 4 channel 240V LED light dimmers. This is installed in the roof and supports 4 buttons to turn on/off/increase/decrease each channel. It uses an AC zero crossing detector circuit and can be configured for leading or trailing edge dimming.

RE: MySensors 2.3.0 released
Hum I am not sure what the deal is here but I have spent the last two days updating and then removing 2.3.0 from Gateways and Repeaters. It completely trashed my 22 node network. I still have some 2.3.0 nodes running but if I installed 2.3.0 and setup #define MY_REPEATER_FEATURE my nodes would crash within about 30 mins of booting. Also on the gateway the through-put of the radio RF24 died to a crawl. I was trying to OTA my nodes and they were going line by line for about 60mins or more each (MYSController). I simply went back to 2.2.0 on Ethernet Gateway made NO other configuration changes and the nodes flashed in less than a minute each.
Since removing 2.3.0 from gateway and repeaters the whole network appears to have stabilised again.

RE: Irrigation Controller
@hek Great thanks - I am setting a pull request right now which fixes another issue with the goGetValveTimes function which causes NACKs due to 3 successive sends to the radio without any pause or delay. This is a simple bug in the code and should not really need a discussion to implement as careful analysis of the DEBUG results will always yield this error. I basically copied the setup code that reads the data - put it in the function and changed the setup to call this updated function.
There is another bug I am trying to stamp out right now which is causing the manual button start to NOT send the status updates to the controller via the radio - again this is a standard bug and may or may not get seen by many if you are not testing the manual button operation. Once this is resolved I will make a pull for it also.

RE: Getting MySensors MQTT Gateway working on OpenHAB 2.2 (Stable)
@fredswed thanks for your comments. I have gone with Ethernet gateway as it works well and at this stage I do not need MQTT - maybe if I play with node-red or something down the track but for the moment happy with Ethernet - it just works. I did have MQTT working but the MYSController connection is a possible problem.
I have also gone to the config files directly and have worked out the bridge setup in the things file and have a few test items running.
Yes backups - done that and have my system backing up to a local NAS box.

RE: 💬 Rain Gauge
I had fake interupts on my device - would work great on test bench then with a 5v dc converter that was noisey plus a longer cable to the bucket I was getting a lot of trips. My fix which solved all the issues was a 0.1uF ceramic cap from ground to the signal pin of the bucket (right at the adruino) coupled with an inline resistor 330ohm to the bucket and a 1Kohm resistor from +5v to the signal pin. This is a basic pull up and debounce system and it manages to hold the 5V via the cap with 100% reliability thus far for 3 weeks including a lot of rain over the last few days. I would draw a circuit diagram if someone could tell me the best program to use?

RE: Irrigation Controller
OK so I have added several pull requests to Github for the irrigation controller. I thought I would now show you may take on the irrigation controller firstly a pic of my unit:
The button on the left that is glowing - turns on/off the LCD backlight as most of the time I do not want to see it and have it glowing at night - this box is mounted on a wall outside my house under the eves. The right button is the flashing led coupled with the manual operation function - I also slowed down the on time for this led again to not glow and flash as much.
As I live in Australia I regionalised the displays for none US dates and here is my final code which is setup for 6 zones. I also made a modification to always switch on Zone 8 as a master valve when any other zone is activated. My original system has a master valve which enables the water supply to the other valves and hence needed to switch this on. If you want to copy my code and remove this it is at line 500 - 501 - just remove the ' - 128' from both these lines. The rest of this code has all the fixes added to the github repo for the Irrigation Controller - enjoy.
/* MySprinkler for MySensors Arduino Multi-Zone Sprinkler Control May 31, 2015 *** Version 2.0 *** Upgraded to http://MySensors.org version 1.4.1 *** Expanded for up to 16 Valves *** Setup for active low relay board or comment out #define ACTIVE_LOW to switch to active high *** Switch to bitshift method vs byte arrays *** Changed RUN_ALL_ZONES Vera device to 0 (was highest valve) *** Added optional LCD display featuring remaining time, date last ran & current time *** Features 'raindrop' and 'clock' icons which indicate sensor is updating valve data and clock respectively *** Added single pushbutton menu to manually select which program to run (All Zones or a Single Zone) *** Added option of naming your Zones programmatically or with Vera (V_VAR3 used to store names) Utilizing your Vera home automation controller and the MySensors.org gateway you can control up to a sixteen zone irrigation system with only three digital pins. This sketch will create NUMBER_OF_VALVES + 1 devices on your Vera controller This sketch features the following: Allows you to cycle through All zones (RUN_ALL_ZONES) or individual zone (RUN_SINGLE_ZONE) control. Use the 0th controller to activate RUN_ALL_ZONES (each zone in numeric sequence 1 to n) using Variable1 as the "ON" time in minutes in each of the vera devices created. Use the individual zone controller to activate a single zone. This feature uses Variable2 as the "ON" time for each individual device/zone. Connect according to pinout below and uses Shift Registers as to allow the MySensors standard radio configuration and still leave available digital pins Turning on any zone will stop the current process and begin that particular process. Turning off any zone will stop the current process and turn off all zones. To push your new time intervals for your zones, simply change the variable on your Vera and your arduino will call to Vera once a minute and update accordingly. Variables will also be requested when the device is first powered on.

Following the instructions at https://MySensors.org include the device to your MySensors Gateway. Verify that each new device has a Variable1, Variable2 and Variable3. Populate data accordingly with whole minutes for the RUN_ALL_ZONES routine (Variable1) and the RUN_SINGLE_ZONE routines (Variable 2). The values entered for times may be zero and you may use the defaulet zone names by leaving Variable3 blank. Once you have entered values for each zone and each variable, save the settings by pressing the red save button on your Vera. Restart your arduino; verify the settings are loaded into your arduino with the serial monitor; the array will be printed on the serial monitor. Your arduino should slow-flash, indicating that it is in ready mode. There are multiple debug serial prints that can be monitored to assure that it is operating properly. * ***THIS SHOULD NO LONGER BE NEEDED*** The standard MySensors library now works. https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads for the I2C library, or use yours Contributed by Jim (BulldogLowell@gmail.com) with much contribution from Pete (pete.will@mysensors.org) and is released to the public domain Modified David Martin.

RE: nrf24 : transmission of data works fine, but constant NACK's produced
@tekka Loaded onto my MEGA based Ethernet gateway connected to openHab using a E01-ML01DP5 with 9db antenna - this previously lasted less than 6 hours. Will advise as testing goes ahead. I do not send much with this unit more receive but have some test nodes I will code to toggle back and forth - I am unable to add my signed nodes to this as yet!
I will also grab my MEGA based repeater on a different network and see what happens this is a nrf24l01+ with pa + lna.

RE: 💬 Building an Ethernet Gateway
I give up - at least if someone is thinking of building this gateway and wanting to use security they can hopefully read this thread before they start and will look at a higher level controller before they purchase the hardware. I am only trying to help others with what to me is still a simple and easy fix alas I must have upset the apple cart.
There is no big problem at all, just that it is really simple to know right now, with technology available today, if you need an Ethernet gateway and signing then use a Mega 2560 or better for the Ethernet Gateway controller to ensure you have the ram. @mfalkvidd - You state variations increase exponentially and most not under library control however using the MySensors Library and building the hardware shown and documented on this page using the sketch provided (completely under control of MySensors) you will need a Mega 2560 or better if you intend to enable signing (also under control of the Library). Do not get me wrong I really love the whole MySensors thing and have over 30 devices up and running and have enjoyed the whole learning thing however simple requirements (IMHO) like this should be detailed.
Hopefully this post will help the next person, it certainly would have help me and I am sure I am not the only one.

RE: BMP/E atmospheric pressure

RE: Irrigation Controller
@Woodside the code in this post is the latest with one exception. I am not using the internal pullup on the waterbuttonPin any more as I have installed a cap/resistor mode to facilitate a hardware debouce. The details of this have been published in the Rain Gauge project (see troubleshooting). Apart from that the above code is fully made for AU dates and is running my system now.
The GitHub version is US date based and not AU converted but has my mods for the gateway comms and some updates - https://github.com/mysensors/MySensorsArduinoExamples/blob/master/examples/IrrigationController/IrrigationController.ino
If you run into any problems or issues let me know.

RE: openHab 2.5.0 Message from Gateway ID 255
@TimO thanks for the pointers. All my nodes were working ok but via a lot of playing around I found a repeater node that also runs a light dimmer (which the light dimmer worked fine and so did all of the repeating functions) was constantly sending an ID request. I disabled the repeater function and flashed it back and it is now not sending these requests. I then deployed another (better) repeater node into the same area and did not catch anymore ID requests so it would appear the repeater was causing the issue. I did flash it again with repeater on but it went bad again so gave that away and now have a different repeater serving that part of the property and no more weird ID requests. Thanks again for your help and continuing work on the binding.
PS: Is there somewhere that we can always get the latest JAR files from, I find I have to troll posts to find links?

openHab 2.5.0 Message from Gateway ID 255
I have just upgraded my Docker based RPI Openhab to 2.5.6 and updated the jar to org.openhab.binding.mysensors-2.5.0-SNAPSHOT.jar
Since I did this and tail the openhab log file I get this:
2020-07-28 16:24:38.576 [DEBUG] [rsAbstractConnection$MySensorsReader] - Message from gateway received: 255;255;3;0;3;0 2020-07-28 16:24:38.580 [INFO ] [rs.internal.gateway.MySensorsGateway] - ID Request received 2020-07-28 16:24:38.588 [ERROR] [rs.internal.gateway.MySensorsGateway] - No more IDs available for this node, you could try cleaning cache file
My Node:3 is a multi function, Humidity, Temp, Light, Rain and Barometric sensor. I believe 255 is used for some other comms as per the docs it is not recommended to be used for nodes. So why this being constantly logged, do I need to add a dummy node 255 or something?
Oh and I have tried doing what it says and cleaning the cache file, I deleted both files in the userdata/logs/mysensors/cache and restarted my docker container.

RE: BME280 node connecting but not showing data
@mfalkvidd Yes seems right but the most confusing part and the one I stumbled on is that on the page https://www.mysensors.org/build/pressure for the sensor the Shopping Guide points you at the BMP280 which as we are identifying is not the relevant item for the project - I followed the provided link and purchased the sensor (after waiting for weeks for delivery) only to find it does not work at all (as I suspect my be the case for @Andrew-Maynard as the sensors does not init and the loop does not run) and hence my code was needed to run the node using the item shown in the shopping guide.

RE: BME280 node connecting but not showing data
I could not make the example BME280 sketch work either and upon investigation the code is not for the standard BME280 it is for the BME280 library by Embedded Adventures - https://github.com/embeddedadventures/BME280. This device is not the same as the cheaper standard BME280 as linked on the forum page. The Embedded Adventure one has humidity, the standard BME280 does not.
Anyway I researched and converted some other BME280 code I found from the SFE_BMP180 library, coupled the Forecast code and created the following sketch for the BME280. You will need to install the SFE_BMP180.h library using library manager

RE: 💬 Serial Protocol - 2.x
I am investigating a problem I have found with I think openHAB but I am not sure if this issue is not related to the Gateway code of 2.3.0.
When a node performs a requestTime() I am seeing this reported:2018-10-09 10:47:13.337 [INFO ] [rs.internal.gateway.MySensorsGateway] - I_TIME request received from 2, answering...
Looks perfect and the node receives the time however I was curious as to why sometimes the node would receive GMT and at other times my local timezone GMT+8. I decided to run the gateway via MYSContoller so I could monitor and log the traffic and I have found the problem. When the Gateway receives the request it responds twice within a few ms of each other, for what reason I do not know but the first response send the local time zone response (GMT+8) and the second is a GMT response. The logs from MYSController for the above report are as follows:
318857 9/10/2018 10:47:19 RX 2 - Irrigation Ctrl (2) INTERNAL C_INTERNAL NO I_TIME
318858 9/10/2018 10:47:19 TX 2 - Irrigation Ctrl (2) INTERNAL C_INTERNAL NO I_TIME 1539082039
318859 9/10/2018 10:47:19 TX 2 - Irrigation Ctrl (2) INTERNAL C_INTERNAL NO I_TIME "1539053233"
Note the quotes where picked up in the copy and paste (I did this several times) so it looks like the body was changed to a string type but I also caught this in the MYSController Debug:
9/10/2018 10:47:19 RX 2;255;3;0;1;
9/10/2018 10:47:19 INFO Reply time request
9/10/2018 10:47:19 TX 2;255;3;0;1;1539082039
9/10/2018 10:47:19 FWD 2;255;3;0;1;1539053233
9/10/2018 10:47:19 TX 2;255;3;0;1;1539053233So I am curious as to where the FWD comes from and why the response body has changed between the TX, FWD & TX?

RE: MySensors binding - confusion with things configuration
I also use the lookup in PaperUI to be sure but it looks like you have added the thing in PaperUI from the inbox. What I would do is delete from PaperUI both nodes. If it is as you say setup in the .things files correctly you will not be able to delete it from PaperUI it will report a problem with any things that are setup in the manual things files.
