Openhab serial gateway and mysensors device discovery - tutorial
-
Hi
I've struggled with openhab for 4 weeks. My last idea to use HashMap for mapping device to id's was not bad but I found much better solution. My major requirements were:- automatic device discover.
- I don't want to use all discovered devices.
- each item have to belong to group "all"
- each new device will be added to groups "unconfigured, unused, all"
- updates for items that belong to unused group are skipped
- if device doesn't belong to group "all" , rule "Arduino sends to Openhab" will try to add this device as a new device
OK lets go
First I have to generate names so I create some HashMap tables using mysensors serial API
- presentationSubTypeToValue - mysensors presentation mode - converts subType (S_DOOR) to value (number) and openhab item type
var HashMap<String, LinkedHashMap<String, String>> presentationSubTypeToValue = newLinkedHashMap( "S_DOOR" -> (newLinkedHashMap("value" -> "0", "comment" -> "Door and window sensors ", "itemType" -> "String"))- presentationValueToSubType - mysensors presentation mode - converts mysensors value to subType and openhab item type
var HashMap<Integer, LinkedHashMap<String, String>> presentationValueToSubType = newLinkedHashMap( 0 -> (newLinkedHashMap("type" -> "S_DOOR", "comment" -> "Door and window sensors ", "itemType" -> "String")),- setSubTypeToValue - mysensors set/request mode - converts subType to mysensors value and openhab item type
var HashMap<String, LinkedHashMap<String, String>> setSubTypeToValue = newLinkedHashMap( "V_HUM" -> (newLinkedHashMap("value" -> "1", "comment" -> "Humidity ", "itemType" -> "Number")),- setValueToSubType - mysensors set/request - converts mysensors value to subType and openhab item type
var HashMap<Integer, LinkedHashMap<String, String>> setValueToSubType = newLinkedHashMap( 0 -> (newLinkedHashMap("type" -> "V_TEMP", "comment" -> "Temperature ", "itemType" -> "Number")),- internalSubTypeToValue - mysensors internal command mode - converts subType to my sensors value and openhab item type
var HashMap<String, LinkedHashMap<String, String>> internalSubTypeToValue = newLinkedHashMap( "I_BATTERY_LEVEL" -> (newLinkedHashMap("value" -> "0", "comment" -> "Use this to report the battery level (in percent 0-100). ", "itemType" -> "String")),- internalValueToSubType - mysensors internal commands mode - converts mysensors value to subType and openhab item type
var HashMap<Integer, LinkedHashMap<String, String>> internalValueToSubType = newLinkedHashMap( 0 -> (newLinkedHashMap("type" -> "I_BATTERY_LEVEL", "comment" -> "Use this to report the battery level (in percent 0-100). ", "itemType" -> "String")),My openhab item name is for example
Switch V_LIGHT_10_0 where
Switch is "itemType" -> "String"
V_LIGHT - type
10 - nodeID
1 - sensorIDbash script: addItem2.sh will add new device to items file
#!/bin/bash #OPENHAB_ITEMS="/opt/openhab/configurations/items/test.items" GREP="/bin/grep" SED="/bin/sed" while getopts ":i:l:f:" opt; do case $opt in i) ITEM_NAME=${OPTARG} ;; l) LINE="${OPTARG}" ;; f) ITEM_FILE=${OPTARG} ;; \?) echo "Invalid option: -$OPTARG" >&2 ;; esac done grep ${ITEM_NAME} ${ITEM_FILE} >> /dev/null 2>&1 || echo ${LINE} | ${SED} -e 's/____/\ /g' >> ${ITEM_FILE}Put this script in /opt/openhab/bin/addItem2.sh
in rules file you have to set variables to your configuration
// ----------- Openhab configuration --------------------- var String OPENHAB_HOME = "/opt/openhab" var String OPENHAB_CONF = "/opt/openhab/configurations" var String SITE_NAME = "test"You can turn off automating my sensors device discovering:
var String deviceDiscovery = "ON" //set to OFFthis is my configurations files:
- "test.items*

Awesome work!
@l154 How can user give item name? Where is discovered device in the UI?Detailed information about discovered device on single node are in SITEMAP_mysensors_nodeId.html location OPENHAB_WEBAPPS ---- not implemented yet
When will you put this file?
Maybe some screenshots explain better..

Items are added to sitename.items file. After you add item to this file every 10s items is reloaded.
User can't give item name. Item name is generated type_nodeId_sensorId, but you can change item description in item file and this desc will be shown as a name.
I needed auto discovery because i'm testing new sensors and this is easier to modify name than create it and modify items file and rules file.

You didn't create group "all" -- The name 'all' cannot be resolved to an item or type. I wrote that every item, have to belongs to group "all" - lower case

Hi, all
I see there is a little misunderstanding. Item won't show automatically in sitemaps. The goal was to add discovered items to an sitemap.items file. After items are added to this file you can use them. You have to remove them from "unused" and "unconfigured " groups and add them to your site maps, your group etc. In rules I prepared two functions one for light and one for dimmer.

HashMap
Hi, your tutorial is amazing, and just what I was looking for, but I´m very new to it, so I´m not sure what I have to do on the start of it. The creation of the names and the HashMap is something that we have to do also or just part of the line of thought? If it´s something we have to do, where do we start? I have my OH on a raspberry PI and know how to use it.

If you have let´s say the "unconfigured" group on your sitemap, and the item is set to that group, it will appear automatically.
