G'day,

I have a Raspberry Pi B+ running a local emoncms with Only a GLCD connect to it at the moment with the Solar PV sample sketch loaded so i could test the RFM12Pi with the Temperature sensor on the GLCD.

The RFM12Pi is working fine, the Input appeared in the local emoncms once both units were turned on and updates every 20's or so with the same temp as shown on the screen (- decimal point).

I setup a process from the input tab with the following option:

Log to Feed  |  Create New:  |  GLCD Temp  |  Fixed Interval No Average (PHPFINA)  |  10 Mins

I check the feed tab and the feed was there as expected.

How every i notice that the size stays at 0.0kb

So i took a look in mysql and found the the updates don't appear to be logged.

1. Null entries in the time and value fields in the Input table

2. No feed_1 table created

3. Null entries in the time, value and size fields in the feeds table

Below are the sql tables from the raspberry pi.

mysql> show tables;

|  1   | node:20:1 |      1      | Node:20 | NULL |  NULL |        1       |      0     | NULL |      5      |
+----+--------------+----------+------------+---------+---------+------------+---------+--------+----------+

If someone could point me in the write direction to fix this that would be great...

Thanks
