Has anyone thought of using serial over ethernet? I would think that you could do that similar to having a straight serial connection. I do believe that ESPEasy supports serial over ethernet. I can check when I get home since that is what I am running on all of my Sonoffs. I am using a custom plugin on my Vera to run them, but I do have a couple spare Sonoffs that I could try a serial connection with. The only thing would be what GPIO pins are available on a Sonoff or other ESP8266 device to act as the serial side of the gateway.
Higher security if you have incoming connections from outside your Lan and more flexibility if you have other devices accessing data directly on mqtt, but if you are running just your simple setup there is no real need
Hi, I know this is an old thread, but it is stil a valid subject to me.
I have had success with arduino pro mini v2 and RFM69W in sleep, but not the high power version RFM69HW.
Arduino+RFM69W sleeps at 5.2micro Amp.
Arduino+RFM69HW sleeps at 420micro Amp.
I have written about it in arduino forum.
I would be glad if someone has a solution for this.
