RPI-Monitor Adapter for ioBroker

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

Important Information

ioBroker needs special permissions to control GPIOs. On most Linux distributions this can be achieved by adding the ioBroker user to the gpio group.

For gpio to work, you need to install libgpiod in version 2.x, before installing the adapter (see below)!

Installation

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 update
sudo apt install -y build-essential python
sudo apt install -y libgpiod-dev

(the last one is only necessary, if you want to work with GPIOs)

Following Objects are available after selection:

CPU

• cpu_frequency
• load1
• load5
• load15

Raspberry (vcgencmd is required)

• cpu_voltage
• mem_arm
• mem_gpu

Memory

• memory_available
• memory_free
• memory_total

Network (eth0)

• net_received
• net_send

SDCard

• sdcard_boot_total
• sdcard_boot_used
• sdcard_root_total
• sdcard_root_used

Swap

• swap_total
• swap_used

Temperature

• soc_temp

Uptime

• uptime

WLAN

• wifi_received
• wifi_send

Configuration

On configuration page you can select following modules:

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

NVME temperature

Since adapter version 2.3.2 you can read NVMe temperature. To do this, you need to install nvme-cli package on your system. You can do this with the following command: sudo apt-get install nvme-cli. You will also need to add the command to the ioBroker sudoers file /etc/sudoers.d/iobroker. Open it with an editor, for example nano: sudo nano /etc/sudoers.d/iobroker and add the following line: nvme smart-log /dev/nvme0 to the bottom.

GPIOs

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:

DHTxx/AM23xx Sensors

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.
