开源软件名称:NorthernMan54/homebridge-dht开源软件地址:https://github.com/NorthernMan54/homebridge-dht开源编程语言:Shell 54.5%开源软件介绍:Supports integration of a DHT11/DHT21/DHT22/DHT33/DHT44 Temperature/Humidity Sensor into hombridge via the BCM2835 library on a Raspberry PI. I have tried numerous other interface methods for the DHT22, and found that this was least problematic. Also includes optional reporting of the RaspBerry PI CPU Temperature. This latest version splits the temperature and humidity into separate sensors, so they are readable from the home screen icon. Historical display of temperature data is available via HomeKit apps thats support graphing. Also support use of multiple DHT22's, see config.json fragment.
1 - Detailed build instructionsFor detailed installation instructions, please see the build instructions 2 - Install and configure required librariesPrior to installation of this plugin, the BCM2835 library needs to be installed. Detailed installation instructions are part way down the page If you run homebridge as non-root user - add it to GPIO group: (in case in logs: bcm2835_init: Unable to open /dev/gpiomem: Permission denied)
3 - Installing the plugin
4 - Configure the PluginA minimal config.json looks like this
Required Configuration options
Optional Configuration Options
config.json SamplesConfiguration - with RPI cpu temperature sensor, requires cputemp program ( Optional )
Configuration - without cputemp
or with multiple DHT22's
Optional cputemp script - install in /usr/local/bin
Output from the cputemp command
ToDoOptional - Enable access to Google to log data and store history charting dataThis presumes you already have a google account, and have access to google drive/sheets already Step 1: Turn on the Drive API a. Use this wizard ( https://console.developers.google.com/start/api?id=sheets.googleapis.com ) to create or select a project in the Google Developers Console and automatically turn on the API. Click Continue, then Go to credentials. b. On the Add credentials to your project page, click the Cancel button. c. At the top of the page, select the OAuth consent screen tab. Select an Email address, enter a Product name if not already set, and click the Save button. I used 'Sheets Data Logger' d. Select the Credentials tab, click the Create credentials button and select OAuth client ID. e. Select the application type Other, enter the name "Drive API Quickstart", and click the Create button. f. Click OK to dismiss the resulting dialog. g. Click the file_download (Download JSON) button to the right of the client ID. h. Move this file to your .homebridge and rename it logger_client_secret.json. Step 2: Authorize your computer to access your Drive Account a. Change to the directory where the plugin is installed i.e. cd /usr/lib/node_modules/homebridge-mcuiot/node_modules/mcuiot-logger b. Run the authorization module node quickstart.js c. Browse to the provided URL in your web browser. If you are not already logged into your Google account, you will be prompted to log in. If you are logged into multiple Google accounts, you will be asked to select one account to use for the authorization. d. Click the Accept button. e. Copy the code you're given, paste it into the command-line prompt, and press Enter. Credits
