@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...
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?
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).
