@mfalkvidd so how do I change the title to reflect "SOLVED"?

I have good news. I used a small prototype board for everything. made sure no line was more than 6 inches long. I soldered (My soldering sucks!) the capacitator right next to the radio and Bahm! Domoticz picked up all powered devices.

Lessons learnt, keep length of your wires short, nRf24 MUST have a decent capacitator to smoothen out power. Don't rely on GPIO pins to power it, use a regulator. Though help may come from all and sundry, its all up to you to check their suggestions... Thanks all for helping me.

I can finally retire my Nano-Serial Gateway! Wont be upgrading for a long time to come

@eiten l think it's A+ it has Wifi and l run it "headless" with my old Nano Gateway connected to the 1 USB. But I'll looking forward to getting the Pi to work as both Gateway and Controller.

I want to use a prototype board and drop the long lines. Plus I'll also bring the cap closer to the nrf24 to see if that helps.

@nono8223 I've this same problem... stock for days. I tried powering the radio directly with a 3.3volts regulator and capciator between GND and 3.3V pin of the nrf24 but still no luck.

I don't want to duplicate posts but the details of my issue can by found here
@Eme said in MySensors Raspberry Pi Gateway + Domotics Controller:

Please someone help me...

@eiten Don't know if the Pi model matters. I used a Pi Model A with wifi.

@eiten Yes what does that mean in English:

@eiten based on the suggestions "leaning towards" powering the rf24 from you and @mfalkvidd l fed the radio a regulated 3.3 with LD33V and l also brought the capacitator near the radio... yet I still cant register the nodes.

Pls what does "TSF:CKU:OK:FCTRL" mean?

Thanks @eiten I thought I already shared that. I just hooked Node 5 to the laptop to get its log...

It still cant find the Gateway, and I see it reads Node 7 and 2 request for registration too.

Hello @mfalkvidd , l am a fan! I very honoured to have you look into my issue... to answer your questions...

No it's another Rf24 but from the same batch as the one on the nano Gateway and all my nodes. I still have a spare one lying around. I'll try it see if it makes any difference.

The Rf24 is powered directly from the Pi with a 220uf cap connected next to GPIO pins as described in the official Rasberry Pi Gateway guide. I'll post a picture of the setup.

Everything is still on the fly with Dupont cables and Leds on a bread board until everything works well.

Concerning proximity of nodes to Gateway and if I've moved them from their original place. Besides the Gateway now lying on my desk, all my nodes are still in their place around the hose. Node ID 2 is the Sprinkler from my kitchen downstairs (over 10 metres away between concrete walls) Node ID 7 is the Gate node outside the house (about 9 meters from my desk) and Node ID 5 which didn't show in the log (probably disconnected at the time) is right next to the PiGateway.

Thanks for your response @Yveaux , l did notice 3 nodes at the time, but perhaps it didn't show on the portion of the log l shared. Yes l had been using a USB serial gateway attached to a Pi3 for over 2 years. I have tried my best to stay away from the "Bleeding Edge" of technology by staying with a stable version that has worked for me. I've been on MySenosors Ver 2.1.1 for a very long time. Just thought to update and Bahm! I'm in trouble. Can't connect to several nodes. Luckily MQTT still works, but all my MySensors nodes are down.

Please someone help me...

I finally made up my mind to move from MySensors Ver 2.1.1 to the new 2.3.2 release. Before now, I had been using a Nano - Rf24 Gateway connected to USB of a Pi2 with Domoticz controller running. This had served me well over the years with minimal issues. I have several Nodes running 2.1 sketches scattered around my home.

From research, I noticed it was possible to run both Gateway & Controller off the Pi without need for additional hardware. I followed the step by step release notes at and also a procedue for building-a-raspberry-pi-gateway.
I used Cleareeprom Sketch to clear one Node (Node ID 5) and proceeded to biuld a new gateway on the Pi itself.

My configuration values were

./configure --my-transport=rf24 --my-rf24-irq-pin=15 --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyUSB020 --my-controller-ip-address=127.0.0.1 --my-port=5003 --my-leds-err-pin=12 --my-leds-rx-pin=16 --my-leds-tx-pin=18

make
tested with sudo ./bin/mysgw
sudo make install
sudo systemctl enable mysgw.service
sudo systemctl start mysgw.service

my "tail -f /var/log/syslog" revealed the following

I can see 3 Nodes (Two Nodes running Ver 2.0 version sketches and one with the new Ver 2.3 sketch) trying to request for registration without luck. This tells me Transport with Rf24 is okay, but nothing else.

What must I do? How can I get the Domoticz to accept the new requests and create the devices? I have deleted the old MySensors hardware from Domoticz but it still wont register.

@skywatch Sorry I didn't respond to this question. I didnt change the sketch. I only updated the library and uploaded to the node with the new Library. DO I have to change the sketch altogether? My sketch is as follows...

thanks @skywatch l took your advice cleared eeprom on only one node, and cloned my SD card before building a Rasberry Gateway/Controller since I was experiencing too much stress with the Nano-RPi gateway.

My Config was like:-

./configure --my-transport=rf24 --my-rf24-irq-pin=15 --my-gateway=serial --my-serial-is-pty --my-serial-port=/dev/ttyUSB020 --my-controller-ip-address=172.0.0.1 --my-leds-err-pin=12 --my-leds-rx-pin=16 --my-leds-tx-pin=18

I changed the Hardware on Domotics to point to the new virtual ttyUSB020 port that appeared on Domotics. but still no connection.

Rasberry Pi Gateway/Conmtroller Tail Log is asfollows

Still no luck. The node still wont present to the new gateway.

What am I doing wrong? All my devices are still down - 4 days on.

@Eme cleared eeprom with the sketch and loaded the Gateway Serial. I now have an error for an #include <nrf.h> I've updated boards and libraries but still can't get past the error

"NRFS Radio is not supported for this platform. " does this mean my Serial GW can't be upgraded since l use NRF24 radios? What am l fling wrong? All my nodes are down. Please help.

@skywatch thanks for the update. Should l write this sketch to the Gateway alone, on each node or on both? Are there any step by step guides to gracefully migrate with? I'm very cautious, I've nodes in faraway places, wouldn't want to have to start all over again.

Upgraded MS library and my my serial gateway sketch from 2.0.0 this evening - went well. Then noticed Nodes nolonger connect... Status LEDs no longer blick. Tried updating one node to 2.3.2 but it still won't conect. Is there a step by step guide? I have over 10 other nodes that Domotics can't find.

Please Help needed I have a Node with Sonar sensor and an digitalRead(A0) value from Node to Gateway. The value shows on Domoticz Hardware TAB, but wont show on Switches. I have stayed up all night looking for solutions without much luck. I sketch is as follows.

@dbemowsk Yes you are right.
Domoticz (the Controller, just like Vera) is the one with the DB. The Gateway just sends messages to and from the controller. MySensors needs a gateway to communicate with all nodes. the Controller automates and facilitates the interactions with the nodes and gateways...

@homer I have no experience with Vera, and only starting out with Domoticz like you, but your MS Gateway just relays the traffic from your nodes to your Controller (Domoticz). it wont have any details to remember or pass on ... its like a listening post for Nodes for onward transmission to controller, Subscribed Brokers or other nodes.

If I am wrong others would correct me.

@eme Okay I solved this by redoing the MySensors Gateway added 4.7uf cap and everything works fine now.

@mickecarlsson I found this out and wrote it above that D6 is not connected at all... but it was promptly swept aside cos nobody had reported it before now. I am glad someone else saw it, and that you had the notion to check. D4 is also not connected to the test area. I have been connecting directly to the Nano.

@sundberg84 Yes you are right I meant to say ProMini not Nano - I have 18 of these PCB - not so happy I have to solder directly to the Arduino - that's exactly what I was avoiding in the first place. Do you have a good relay block sketch that works? Much appreciated if you can help.

One last thing, I am trying to run a node off a 12Volts battery, can you explain this image below again?

• Will this work for a 5V Promini?
• What are the blue lines? and
• what are the red lines?

Hello All...
I am having a problem with sending a 4 relay block code to Domoticz Gateway … sometimes the relays switch without any problem, but other times, it breaks out to an "Error sending switch command".

I saw an earlier post at https://forum.mysensors.org/topic/4658/solved-error-sending-switch-command with the same issue. The solution proffered there didn't have much impart. One second it's working fine and the next its breaking into errors.

I couldn't find a .1uf Capacitor, so I used an electrolytic 1uf instead. Worked fine in another Nfr+ radio Project, but I don't know if that's the problem here. My sketch is a follows:-

I hear tagging this trio solves problems, so here goes... @tekka, @kk02067 and @hek to help me with this one. So sorry guys.

@Sunberg84 I bought them off Ebay via this very site... The Packing List reads Shipped by Abdera's Sundberg Ostra Gransgatan 2, Lonsboda, Sverige 28070, SE. I believe that's you.
Well I am forced to solder directly to the Nano pins, and so far so good. I think you should help with a 4 relay sketch that works. My appears to be a hit and run, works in the morning and fails after a while. but I am learning as I go.

I eventually got it to work. I am not using the EasyNewbie to power the load (its for 24volts swimming pool light). Couldn't get the 4th relay to work - not sure why its not responding to the controller. but I noticed some bug with my batch of 16 PCB -

Okay I think I have seen some bugs... my batch of EasyNewbie Rev 10 has some hardware issues - The provisions to attach sensors are not correctly marked. D6 doesn't actually connect to D6 pin on the Arduino (must have failed a via somewhere). I am not sure how many pins are used for the radio and other components, but if you intend to use this for a small project, I will avoid D8 - D13 as they appears to be taken. D1 and D2 are used for the TX & RX so you only have D2 - D6 to play with (more than enough pins for a newbie if you ask me).

@sundberg84 I have the Domoticz log below. but just incase it doesn't reveal much, do you have a working sketch for EasyNewbie and a 4-relay module block?

Hello Sundberg84 et al,
I purchased Easy Newbie PCB (Rev 10) with the hope of jumping into the IoT rave... I tried to create the Gateway - and it works perfectly. I also found and created an advanced Water Sprinkler MyS project by Pete and Co!... that also worked perfectly.

However, I cant seem to get simpler beginner sketches to work with EasyNewbie. I have soldered the need components (the regulated version). I plan to connect to a 4 relay module, but for now, I am simulating the relay with a simple LED attached to D2. I have uploaded the following sketch which was originally written for version 1.0 MySensors - but have been corrected using guidelines I found for converting 1.0 - 2.0 version. but still no cheese - the controller (Domoticz) displays the Node, but not the complete child nodes, - the LED connected to pin D2 (or D3, D5..) on the Easy Newbie doesn't light up even when I toggle the switches and devices on controller. Don't know what I might be doing wrong, please help.

@floris can you post the final sketch you used? I am having the same issue.
