ECMD¶

Requirements¶

The ECMD plugin connects to an AVR microcontroller board with ethersex firmware via network. The ECMD protocoll provides access to attached 1wire temperature sensors DS1820.

Supported Hardware¶

8-bit AVR microcontroller boards with network support, like NetIO (Pollin), Etherrape (lochraster.org), etc.
1-wire temperature and other sensors

* - DS1820 (Temperatursensor) * - DS18B20 (Temperatursensor) * - DS1822 (Temperatursensor) * - DS2502 (EEPROM) * - DS2450 (4 Kanal ADC)

Configuration¶

plugin.conf¶

You can specify the host ip of your ethersex device.

[ecmd]
    class_name = ECMD
    class_path = plugins.ecmd
    host = 10.10.10.10
#   port = 2701

This plugin needs an host attribute and you could specify a port attribute which differs from the default ‘1010’.

items.conf¶

The item needs to define the 1-wire address of the sensor.

ecmd1wire_addr¶

ecmd1wire_addr = 10f01929020800dc type = num

Example¶

Please provide an item configuration with every attribute and usefull settings.

# items/my.conf

[someroom]
    [[temperature]]
        name = Raumtemperatur
        ecmd1wire_addr = 10f01929020800dc
        type = num
        sqlite = yes
        history = yes
        visu = yes
        sv_widget = "{{ basic.float('item', 'item', '°') }}" , "{{ plot.period('item-plot', 'item') }}"
