TempServer

Intro

TempServer is a Client/Server application that can grab temperature from many remote sensors on the same network and present them in an easy to read format.

Installation

1. Compile the server on a raspberry pi
   1. Install go

   > apt-get install golang
   

   2. Compile

   # Assuming a functional $GOPATH
   > go get -u github.com/maxrenaud/tempserver/server # For the server
   > go get -u github.com/maxrenaud/tempserver/server # For the client
   

2. Configure
   1. Copy the sample json config from github.com/maxrenaud/tempserver/server.json.sample to an accessible location like /etc/tempserver.json. For the client.json.sample, I recommend puttint it in your home directory
   2. Edit the copied file to match your desired configuration
3. Test
   1. Launch the server

   > server -config="/etc/tempserver.json"
   

   2. In a different terminal, try the client

   > client -config="~/client.json" # -config not required if client.json is in the current directory
   

4. Configure the server to start at launch (Systemd)
   1. Copy the tempserver.service file to /etc/systemd/system

   > sudo cp tempserver.service /etc/systemd/system
   

   2. Edit the file and change the ExecStart variable to match where you installed the server
   3. Configure the service to come up at boot time

   > sudo systemctl enable tempserver
   

   4. Reboot the Pi. Alternatively, you can manually start the service

   > sudo systemctl start tempserver
   

Details

In server.json, the sensor and sensor_params are currently as follow:

1. sensor

   1. "tempAlert" for the TempAlert.
   2. "ds18b20" for the ds18b20 chip
   3. "fake_temp" for a fake module that always reports the same temperature.

2. sensor_param. There are the string parameters to pass on to the sensor module

   1. "tempAlert" takes one parameter, the location of the tempAlert. E.g: /dev/ttyUSB0
   2. "ds18b20" does not have any parameters
   3. "fake_temp" takes one parameter, the desired temperature output
