@jkandasa Thanks very very much!
I need to setup two or more "controllers" and a requeriment is to use serial gateway (Arduino as serial gateway connected to raspberry).
Is it possible?
Can I setup two controllers listening to same serial port?
Can I use MyController configured with serial gateway and publish all messages to MQTT?
Is there another alternative?
First of all, you guys are the best, thank you for this great project and for all the effort you have put into it.
Henrik, I wanted to ask if you know low-cost WIFI modules ESP8266 that have been recently released to the market.
I've seen some experiences of using these modules with Arduino and seem promising.
In my opinion they can be a good alternative to the nRF24L01 +. And as WIFI modules you might think solutions where it is not required to have a controller and send the information directly to the cloud.
Do you think these new modules could be useful for the project?
