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

@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...

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

@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.
