Sending data to RFM12 nodes with emonhub/emoncms

Hi,

I have multiple tinyTX (https://nathan.chantrell.net/tinytx-wireless-sensor/) sensors working with my emoncms. At the moment the sensors just sending data (power meter, temperature etc.).

I wonder if I can send data so those nodes!? I installed nodes module but I dont want to install redis server. Is there another possibility to send data to nodes in a network group using emoncms?

best regards,

Christian
