SMTherm - Smart Manageable Thermostat daemon

============================================

SMTherm is a [thermostat](https://en.wikipedia.org/wiki/Thermostat) [daemon](https://en.wikipedia.org/wiki/Daemon_(computing)) written in C that monitors the ambient temperature using DHT22 sensors.

It designed to run on [Raspberry Pi](https://en.wikipedia.org/wiki/Raspberry_Pi) and can even take into account the data of several thermometers

and make complex decisions about starting or stopping the heating.

The program communicates via a TCP interface and, in addition to controlling the heating,

stores the temperature data of the last 3 days in a [ring buffer](https://en.wikipedia.org/wiki/Circular_buffer).

The SMTherm only have TCP interface, the GlowDash: https://github.com/hyper-prog/glowdash can controls it.

Compile / Install

-----------------

Require wiringPi and CURL libraries

    $make

    #make install

Run as systemd daemon

---------------------

Create systemd start file /lib/systemd/system/smtherm.service

    [Unit]

    Description=SMTherm thermostat daemon

    After=network.target

    [Service]

    Type=forking

    ExecStart=/usr/local/bin/smtherm /etc/smtherm.conf

    Restart=always

    User=root

    Group=root

    [Install]

    WantedBy=multi-user.target

After the file created, edit a sample config file and place into /etc/smtherm.conf

Eenable and start the service

    systemctl daemon-reload

    systemctl enable smtherm.service

    systemctl start smtherm.service
