which hardware model must to be used for ethernet gateway ?

[mickaelh51]

Hi,
Actually I'm using an Arduino UNO to be the ethernet (MQTT) gateway.
But, I feel that Arduino UNO is too low when there is many sensors.

Do you have an experience with UNO or MEGA to be a MQTT Gateway ?
which hardware to choose ?

thanks in advance

Why do you feel that way? Can you give some examples of limits/issues you've encountered using an Uno?

Hi,
No problem ;)

I have only 3 sensors in test. But with this nodes I feel my gateway is low.
When I send an order from MQTT (Ex "On" command to specific relay), it's not in real time (few seconds to execute this order).

But when I shutdown 2 nodes / 3. I saw the same order seems faster.

So, my question is: Is there a recommendation for gateway hardware ?

thanks and happy new year 2016 ;)

@mickaelh51 If you feel the need for more processing power, an ESP8266 based gateway could be interesting.

ESP8266 is faster than W5100 ok thanks.
but if I want work with ethernet only ?
