- Jan 5, 2011Thanks for the rundown. I had considered using the tol but wanted a quick and easy way to get the temps from one place to another.
I wrote a udpserver in Perl that runs and just listens for data on a port at my home location. This location has a static IP so the place I want to monitor sends a udp packet every 15 minutes with the latest 1wire data. There is no handshaking. This is over the internet and it works fine. I have not missed a 15 minute update and even if I did miss one it would be a trivial problem. On the home router I just open up the selected port to the machine running the server. Security has not been a problem. I only except data with a certain PW in it, I only accept 256 characters or less, and I only allow one reception every minute. Since there is no handshake response anyone that happens to send data to that udp port would have no knowledge they are even talking to an active machine. Simple but it works.
