RPI-Monitor implementation for integration into ioBroker. It is the same implementation as for iobroker.rpi, but with GPIOs.

Works only with node >= 0.12

ioBroker needs special permissions to control GPIOs. On most Linux distributions this can be achieved by adding the ioBroker user to the gpio group (recommended) or running ioBroker under root (less secure).

After installation you have to configure all required modules via administration page.

After start of iobroker.rpi, all selected modules generates an object tree in ioBroker within rpi.. e.g. rpi.0.cpu

Be sure, that python and build-essential are installed:

sudo apt-get update
sudo apt-get install -y build-essential python

Following Objects are available after selection:

• cpu_frequency
• load1
• load5
• load15

• cpu_voltage
• mem_arm
• mem_gpu

• memory_available
• memory_free
• memory_total

• net_received
• net_send

• sdcard_boot_total
• sdcard_boot_used
• sdcard_root_total
• sdcard_root_used

• swap_total
• swap_used

• soc_temp

• uptime

• wifi_received
• wifi_send

On configuration page you can select following modules:

• CPU
• Raspberry
• Memory
• Network
• SDCard
• Swap
• Temperature
• Uptime
• WLAN

• Odroid C1
• Raspberry Pi 1

You can read and control GPIOs too. All what you need to do is to configure in the settings the GPIOs options (additional tab).

After some ports are enabled following states appear in the object tree:

• rpi.0.gpio.PORT.state

The numeration of ports is BCM (BroadComm pins on chip). You can get the enumeration with gpio readall. For instance PI2:

You can read from DHT11, DHT22 and AM2302 temperature/humidity sensors.

Connect such a sensor to a GPIO pin as described on the node-dht-sensor package page. Multiple sensors can be connected to multiple pins (this is not a bus system) as discussed.
