Install samba and mosquitto (MQTT)

https://github.com/home-assistant/hassbian-scripts

sudo hassbian-config install mosquitto
</code><code>sudo hassbian-config install samba

1 2	sudo hassbian-config install mosquitto </code><code>sudo hassbian-config install samba

Install pilight

http://kleine-nerdprojekte.blogspot.ch/2014/02/auslesen-von-temperaturwerten-der.html

https://www.pilight.org/get-started/installation/

Set port for deamon:

https://wiki.pilight.org/doku.php/settings

vim /etc/pilight/config.json

1	vim /etc/pilight/config.json

And add the following next to "webserver-port": 5001,

"port": 5000,

1	"port": 5000,

Start daemon with the following command if pilight-reveive says no pilight ssdp connections found (use option -D for debugging purposes):

sudo pilight-daemon

1	sudo pilight-daemon

Set ID’s for Stations

I bought two of these: http://www.pearl.ch/a-NC7159-3041.shtml

Monitor sent data with the following command:

sudo pilight-receive

1	sudo pilight-receive

Example of Data:

{
        "message": {
                "id": 10,
                "temperature": 21.3,
                "humidity": 19.0,
                "battery": 1
        },
        "origin": "receiver",
        "protocol": "alecto_ws1700",
        "uuid": "0000-b8-27-eb-cad9b1",
        "repeats": 1
}

{

"message": {

"id": 10,

"temperature": 21.3,

"humidity": 19.0,

"battery": 1

"origin": "receiver",

"protocol": "alecto_ws1700",

"uuid": "0000-b8-27-eb-cad9b1",

"repeats": 1

}

Here the ID of the Station is 10.

Add Sensor in Home Assistant config:

  - platform: pilight
    name: 'Sensor 1'
    variable: temperature
    payload:
      id: 10
    unit_of_measurement: '°C'

- platform: pilight

name: 'Sensor 1'

variable: temperature

payload:

id: 10

unit_of_measurement: '°C'

Activate HTTPS(TLS) with Let’s Encrypt

https://home-assistant.io/blog/2015/12/13/setup-encryption-using-lets-encrypt/

Then fix permissions (as user pi):

cd /etc/letsencrypt
sudo chown -R root:homeassistant live
sudo chown -R root:homeassistant archive
sudo chmod -R 755 live
sudo chmod -R 755 archive
sudo systemctl restart home-assistant@homeassistant.service

cd /etc/letsencrypt

sudo chown -R root:homeassistant live

sudo chown -R root:homeassistant archive

sudo chmod -R 755 live

sudo chmod -R 755 archive

sudo systemctl restart home-assistant@homeassistant.service
