You are great guys! It compile already, later I will also check the functionality

Dear All,

the reliability is the key of the system for me. So I decide to have local functions, that do not need gateway/HUB to be usable. I use Domoticz. In my primary setup, there is my Domoticz server on RPi 3 and multiple Arduino Mega as Serial Gateway. These Mega are controlling lights and Roller Shutters in my house. Every light/blind has it own button, connected to Mega's Input pin. The same Mega is controlling also the relays. The adventage is that no metter if there is Internet or even if Domoticz Server is running, the local buttons and relays are always working - domoticz is just an "extra feature" for my system.

The problem is, when I would like to add some extra devices connected by nrf24l+ and have the same functionality (this means, that the local function is always available, also without connection to gateway), there is a problem. As long, as the slave cannot reach the gateway, the arduino's loop function is not running. Is it possible to get the loop function running even without the gateway on the slave?

WOW, just find that PJON protocol, quite good stuff! Working more reliable than RS485 on my work table

I'm creating smart home solution that will work 100% on cable. Because there are some known issues with RS485, PJON would be the great alternative for my project. Is there an official support for MySensors already?

It works, thank you

@giovanni-blu-mitolo would it be possible for you to refresh the PJON transport layer? Maybe even try with new pull request for PJON transport? I think I'm out of skills to do it by myself. The phissically setup is quite easy, you need one Arduino board as Serial Gateway and one as node. The communication is then running over PJON between arduinos. From Gateway you can see over Serial Monitor if the communication is running well.

I'm trying to build a floor heating controller for all my house. The idea is to have an Arduino (probably ESP8266 with switched off WiFi) with OLED display (SH1106 using u8g2 lib) and BME280 sensor (Temp+Baro+Hum) in each room. All these should communicate with Arduino Mega as Serial Gateway and main controller for the Valves. For now the only problem is the communication between Arduino Mega and multiple ESP8266 over PJON. It would be even enough to get it work outside MySensors, but I get some trouble. For test I have programm the ESP8266 room thermostat that is communicating with other ESP8266 over PJON. But sometimes I cannot get any data over PJON. Have no idea where is the problem, sometimes it is working, sometimes not... Do you think, that the problem could be SW i2c for the OLED diplay?
