dht11-to-mode

Simple program for Rapsberry Pi to collect dht11 sensor data and publishing them as events to MODE.

Usage

First, you have to connect your Raspberry Pi and dht11 sensor apppropriately.

Temperature monitoring with Raspberry Pi and DHT11/22 temperature and humidity sensor - Documentation - Documentation
DHT11 Humidity & Temperature Sensor Module | UUGear

Then, download dht11-to-mode binary to /home/pi/.

$ cd /home/pi/
$ wget https://dht11-to-mode.jp-east-2.os.cloud.nifty.com/dht11-to-mode
$ chmod a+x dht11-to-mode

Write your configuration to /home/pi/.env:

MODE_ENDPOINT=<Your MODE endpoint>
MODE_DEVICE_ID=<Your device's ID>
MODE_DEVICE_API_KEY=<Your device's API Key>
INTERVAL=<Interval in seconds>

And, start the program:

$ sudo ./dht11-to-mode
2016/07/17 06:24:51 [dht11] Triggering event: {HomeId:0 Timestamp:0001-01-01 00:00:00 +0000 UTC EventType:dht11-start EventData:map[value:1] OriginDeviceId:0 OriginDeviceClass: OriginDeviceIp:}
2016/07/17 06:24:52 [dht11] Triggering event: {HomeId:0 Timestamp:0001-01-01 00:00:00 +0000 UTC EventType:dht11-temperature EventData:map[value:30] OriginDeviceId:0 OriginDeviceClass: OriginDeviceIp:}
2016/07/17 06:24:52 [dht11] Triggering event: {HomeId:0 Timestamp:0001-01-01 00:00:00 +0000 UTC EventType:dht11-humidity EventData:map[value:45] OriginDeviceId:0 OriginDeviceClass: OriginDeviceIp:}
2016/07/17 06:24:52 [dht11] Triggering event: {HomeId:0 Timestamp:0001-01-01 00:00:00 +0000 UTC EventType:dht11-retried EventData:map[value:0] OriginDeviceId:0 OriginDeviceClass: OriginDeviceIp:}

Run as a service with systemd

Add /etc/systemd/system/dht11-to-mode.service:

[Unit]
Description=DHT11 to MODE
Wants=network-online.target
After=network.target network-online.target

[Service]
Type=simple
EnvironmentFile=/etc/default/dht11-to-mode
ExecStart=/home/pi/dht11-to-mode
Restart=always

[Install]
WantedBy=multi-user.target

And add: /etc/default/dht11-to-mode:

MODE_ENDPOINT=<Your MODE endpoint>
MODE_DEVICE_ID=<Your device's ID>
MODE_DEVICE_API_KEY=<Your device's API Key>
INTERVAL=<Interval in seconds>

Then you can start service as follows:

$ sudo systemctl start dht11-to-mode

Enable service to start automatically after a crash or a server reboot.

$ sudo systemctl enable dht11-to-mode
