Hello,

I have 3 whisper nodes that will have various sensors connected to them for my home automation system. The main drive for testing those nodes is the battery life. Previously I had tested with the arduino mini pro but the battery lasted only 3-4months using a temp / humidity sensor (DHT22). 

I am using the mysensor libraries. Initial testing is successful, the nodes are sending sensor data back to the receiver node (gateway)
The challenge is to be able to send the data to my home automation central controller (openhab) that is running in a raspberry pi. I know that we can use the serial connection but I would like to avoid that. 

Is it possible to connect a funduino w1500 ethernet module to the receiver whisper node ? The idea is to use ethernet to send all the sensor data via MQTT. If so, would it be possible to indicate how to connect it ?

Many thanks,

Hello cgeorgia,

I have no experience with the Ethernet module you listed. Saying that, most of those modules communicate with the MCU via the SPI pins. You just need to make sure the ethernet module plays nicely with other SPI devices on the same bus as well need to pick one or two extra pins for Interrupt and Chip-Select.

Maybe have a look on this post: https://www.thomaslang.nl/talk2-whisper ... tion-code/ - The user utilized an ESP8266 as Wireless gateway for the Whisper Node.
