That's the problem, i don't know what exactly happened/caused this. That's why i'm asking for working solutions/versions so i can try to trace back what might be wrong with my setup.

Also now i remembered that i had to renew gateway with esp8266 since previous broke down. I don't know for sure that i had previously ota feature for gateway enabled.

I remember when i got it first working year(s) ago i tried also different bootloaders, fiddled with fuse settings and eventually got it working perfectly, but now (since i've updated arduino) maybe my board settings are incorrect.

Select temp sensor and click notifications, then:

Restarting domoticz might help next time, when you have original code running on that node again.
Also some PIR cause radio interference, if i remember correctly, then hc sr501 should be ok.

In case someone has similar issue:
Running everything latest up to date.

Raspberry pi zero w with nrf24 connected directly on GPIO and domoticz. Had to have startup delay on mysgw service since domoticz wouldn't or couldn't start automatically on boot.
So i added to:
sudo nano /etc/systemd/system/mysgw.service

[Service]
ExecStartPre=/bin/sleep 10

Maybe 10 seconds is overkill, but at least it works now.
With raspberry pi 3b+ there wasn't that issue.

Also in domoticz had to use raspi ip address, when setting up mysensors LAN gateway address, instead of localhost 127.0.0.1

And myscontroller OTA updates are working too.

Nrf is long range model?
PA/LNA module.

@cabat said in MYSBootloader 1.3.0-beta.3:

@iguaan Try to set MY_RF24_PA_LEVEL to RF24_PA_MIN on gateway then use NRF24L01+PA+LNA module - in my case the OTA begin work perfect!

Well finally got time to try it out and it worked like a charm, thank you!
Also no problem with a node that is about 1,5m away from GW.
LOW also worked, but OTA was slow.

Well found the problem.
I had also changed gw nrf module to NRF24L01+PA+LNA 2.4GHz:
and it seems to be the issue.
Although regular traffic monitoring etc is working ok.
Changed back to usual nrf24l01+ module and updates are working again.
Both variants are ali merchandise.

Hi, have been using myscontroller more than a year now and at some point i couldn't use OTA on devices, all the sensor data is coming in nicely. I don't know if it was due to updated arduino or i messed up something in my doards.txt or something else...
So question is if someone can give me versions/links to working solution?
https://github.com/mysensors/MySensorsBootloaderRF24/tree/development doesn't work.

I'm using ProMini 16Mhz with external oscillator. Arduino is 1.8.13, MySensors 2.2.2,
Myscontroller 1.0.0beta:b3316.

I have created a weather sensor which has hum, temp, baro, predicition and lux.
Aslo i have attached there another ds temp sensor (for node internal temp).
Problem is that when i update fw over ota or reboot node, it'll occasionally detect sensors all mixed up:
temp/hum, temp, baro/temp/hum etc... Also when it does that, not all the data will be updated on combined sensros.
Is there a way to present the sensors to domticz so, that it recognises 1 combined weather sensor and then others.
I have tried with all different Sensor ID's 1-4, lux id5 and internal temp id6.
Also tried with giving same sensor ID number to hum, temp, baro and predicition.
Domoticz detects it as a combined sensor, but it doesn't update all values after initial value has been sent.
If i monitor the data on myscontroller, all the variables are updating on the node.

Hi,
i have similar problem with domoticz and mysensors.
Firstly, i can't get current dim level from domoticz on startup.
Secondly if i start arduino and controll it over domoticz only, dimming and on/off works. If i turn the rotary knob, domoticz commands won't work.
In serial monitor i see that new dim value has been received:

    Serial.print("Fading level: ");
    Serial.println(dimValue);

but output doesn't change. If i turn knob on rotary, value in domoticz changes.
I removed eeprom writes and rotary button. Only dims to off/on or domoticz commands off/on.
Domoticz 4.10171, Mysensors 2.3.1, ide 1.8.10
