    The note before the example sketch states that you should use the "modified" library from MySensors examples. But as of today, with MySensors 2.3.2 and Arduino 1.8.15 I used the standard DallasTemperature library (provided by the Arduino's Libraries manger) with no problems at all. Using the "standard" Arduino libraries is a grate advantage, so I the custom library is no more used, it could be useful to update the guidelines in the page. Stefano

    @ricorico94 welcome to the MySensors commu ity! All you need to do when switching from raspberry pi gateway to ethernet gateway is change the "hardware" configuration in Domoticz. However, if you are just starting out, don't use this gateway. It works for MySensors 1.x only. Use the new raspberry pi gateway instead.

    @axillent said: @celonunes it is not my solution) it is a way of using 1.4.1 with multiple gateways I'm aware of this. @lunarok your wish may become possible in future developments using MQTT

    Found these bootloaders and using the 1MHz for some low power experiments. I did get this error message when burning the bootloader (using USBASP programmer) : "avrdude: WARNING: invalid value for unused bits in fuse "efuse", should be set to 1 according to datasheet This behaviour is deprecated and will result in an error in future version You probably want to use 0xfd instead of 0x05 (double check with your datasheet first)." The bootloader woas succesfully burned so the message was informational. I did look into this and made the following changes in boards.txt : I changed all the lines containing "......bootloader.extended_fuses=" There are multiples sections in the file that have these lines. old value -> new value 0x04 0xFC 0x05 0xFD 0x06 0xFE 0x07 0xFF I used this site link text for calculating the new values for the extended fuse. Now the error message is gone. Maybe this is of any help when using these bootloaders.

    Thank you @JeeLet ! I've been struggling with missing msgs for years with my Arduino Mega I changed pin and no issues! :D In the pjon code I've reached to list of tested pins that communication works properly https://github.com/gioblu/PJON/blob/38e36bb1228c1690143cfbf693a0bcb809514d6c/src/strategies/OverSampling/README.md?plain=1#L12

    I was wondering about the lengths for the antennas mentioned on this page. For 868Mhz is mentioned a length of 82.2 mm on this page. The length most often mentioned over the internet - as first result of the 1/4 wave calculation - is 86,5mm. Searching a little deeper through the internet, i found that the antenna should be "a little shorter". Then they end up with around -1cm shorter or something around or more. One page mentioned the physically effect that the wave is moving in chopper around 5% slower as the theoratical speed. If i substract 5% of 86,5mm i end up with the here mentioned 82,2mm. I was very suprised about the different "approaches" for such a basic thing as antenna length every single . As most of the application over the internet seem to work somehow with all that different lengths, it seems to be just a fine-tuning thing. Anyway, i think it would be nice to mention this details here because most people will wonder about the 82,2mm in the first view... best regards Jens

    Hello, For a project wtih a fablab, we have using a Li-Polymer Charge Management Controllers MCP73831 You can have free "sample" for prototype if you ask directly to the factory, perhaps it could be faster.

    @Eawo Domoticz groups sensors after the order you present them in, see: https://forum.mysensors.org/topic/5132/ds18b20-ans-sht31-d-show-up-as-combined-sensors-on-domoticz/15 I send every 5 minutes and check the value before so that I only send if the value has changed I have been running my sensor for nearly 2 months now and battery level has only decreased 1-2% Make sure you use 1 MHz bootloader

    @lood29 That is correct, assuming the same radio technology is used. Typically, you set up a separate gateway because you want to run a sensor network on a different radio family due to longer distances or similar.

    Hi All, I'm trying a different approach, on how to use just the top (sensor) part of the livolo touch switch, but at the moment, i'm stuck at the PIC16f690 microcontroller functions in order to power up the LED. I'm using a Livolo VL-C601-2 model and based on the wires on the top part, i tried to make a diagram to batter understand the schematics. (Please note that i'm missing some wires and that i have not drawn all the wires from all the pins as i could not see all of them. If something is wrong, please let me know.) What i don't understand from the diagram below, is how does the PIC16F690 controls the two LEDs (red and blue) using only the RB4 (13) pin. From the datasheet link here i can see that the Pin 13 (RB4) has: RB4/AN10/SDI/SDA and supports IOC Can someone please explain to a noob in electronics how does this work and how does the pic switches from one LED to the other ?

    Hi @CyborgAndy many thanks for providing the binding update for MySensors 4.0.4! I upgrade my OpenHAB 3.4.4 a few minutes ago to 4.0.4 successfully with your binding update. I use a USB connected serial-gateway. The OpenHAB manual installation upgrade works perfect. I need to do afterwards the following steps in the Karaf console, to get the gateway online again, after the update: feature:install openhab-transport-serial feature:install openhab-core-io-transport-mqtt feature:install openhab-core-io-transport-serial-javacomm Many thanks again! kerberos

    @alexsh1 Indeed, there is a solderpad near to the D2 pin which needs to be closed (connected) to allow the IRQ signal to go to D2, so one can use the radio

    i built the ethernet gateway with the ENC28J60 module, arduino nano v3.0 and RF24 radio, using this guide and there are three problems which i'm not being able to solve (i used the https://github.com/mysensors/MySensorsArduinoExamples/tree/master/libraries/UIPEthernet, as suggested). fixed ip, connected to power supply, ethernet cable and usb - ping works, but HA does not "sees" fixed ip, connected to power supply, ethernet cable but no usb - ping does not works ???? commented ip definition, to enable dchp - does not work. seams the instructions are outdated - i really need help to make it work. thx

    The 2.5-version of the binding does not work out of the box in OpenHAB 3 for me. 2020-12-22 22:53:34.555 [WARN ] [org.apache.felix.fileinstall ] - Error while starting bundle: file:/usr/share/openhab/addons/org.openhab.binding.mysensors-2.5.0-SNAPSHOT.jar org.osgi.framework.BundleException: Could not resolve module: org.openhab.binding.mysensors [272] Unresolved requirement: Import-Package: org.eclipse.smarthome.config.core at org.eclipse.osgi.container.Module.start(Module.java:444) ~[org.eclipse.osgi-3.12.100.jar:?] at org.eclipse.osgi.internal.framework.EquinoxBundle.start(EquinoxBundle.java:383) ~[org.eclipse.osgi-3.12.100.jar:?] at org.apache.felix.fileinstall.internal.DirectoryWatcher.startBundle(DirectoryWatcher.java:1260) [bundleFile:3.6.4] at org.apache.felix.fileinstall.internal.DirectoryWatcher.startBundles(DirectoryWatcher.java:1233) [bundleFile:3.6.4] at org.apache.felix.fileinstall.internal.DirectoryWatcher.doProcess(DirectoryWatcher.java:520) [bundleFile:3.6.4] at org.apache.felix.fileinstall.internal.DirectoryWatcher.process(DirectoryWatcher.java:365) [bundleFile:3.6.4] at org.apache.felix.fileinstall.internal.DirectoryWatcher.run(DirectoryWatcher.java:316) [bundleFile:3.6.4] I guess it might have something to do with this? https://community.openhab.org/t/guide-binding-development-changes-for-openhab-3-from-2-5-x/104134 Namespace change of openHAB core classes With the migration of Eclipse Smart Home to openHAB the namespace of all classes in openHAB core needed to be changed. This means all imports done by bindings that refer to org.eclipse.smarthome have been changed to org.openhab.core. With your binding code you can simply do a file level replace of this text string in the java source files to migrate the binding. On linux you can use the following commands in you src/main/java directory: find . -name *.java -exec sed -i "s/org.eclipse.smarthome.core/org.openhab.core/g" {} ; find . -name *.java -exec sed -i "s/org.eclipse.smarthome/org.openhab.core/g" {} ;

    Found the solution tanks to watou user in OpenHab Forum. Switch node2_sw2 "sw2 send + recieve example" (node2,all) {mqtt=">[mysensor:MyMQTT/21/2/V_LIGHT:command:OFF:0],>[mysensor:MyMQTT/21/2/V_LIGHT:command:ON:1],<[mysensor:MyMQTT/21/2/V_LIGHT:state:MAP(1on0off.map)]"} The secret is in the :state: declaration on the MAP!

    @guillermo-schimmel Thanks a lot ! I got it all up and running node a couple of nodes. But now I confused myself . I got an Arduino Nano as a node that also acts as a repeater, what bootloader can I push into that one? I assume anycahnnel and 16MHz should do the trick since it got that crystal attached. And also one thing that is not really clear in my head, I set the "Fuses&Lock bits" with the AVRDudess for my 328P barebone. But do I really need that? . If I load the bootloader in ARduini IDE for example I specify all those settings in the "board.txt" file. Or is that just to tell the IDE what settings is on the chip ? If I clear these two things up I think I got everything sorted now =)
