How do I read temperature value returned from my device?

[murf24 (Jeff Murphy)]

I’m sending out a command (temp:) to my device and my device responds with only the temperature value 66.2. From my log it looks like it’s trying to process through various .map files. I really just need to display the value in my OpenHAB. How can I display this value?

I’ve attached my log.

Thanks,
Jeff Murphy

Please share your .items file contents to see what might be wrong.

I really just need to display the value in my OpenHAB

I suggested an approach to a similar problem in this thread:

TCP Binding status polling

Hi, I’m really new to openHAB (first day) and I have a question on how to setup my specific scenario. My house was built with a “pre domotica” option. It simply means that I have a relais and dimmer module attached to my lights. The system is using UDP commands to turn lights on and off with a fairly easy protocol. I already managed to turn a light on and off trought the web interface. main.items {udp=">[ON:10.10.1.30:1001:'MAP(my.garage.map)'] >[OFF:10.10.1.30:1001:'MAP(my.garage.map)']"}…
