OpenHAB 2 & Arduino IDE, Latest Installs

        OpenHAB & Arduino IDE, Trying Latest Installs

At a place I will call Location A, I have this setup running well (with a glitch or two) on a Windows 7, 64 bit laptop: OpenHAB2.1.0, including the Weather 1.xx binding (using the Weather Underground service). I installed OpenHAB 2.1.0 totally with text files (not PaperUI). 

This thread gave my case for configuring OpenHAB 2 (OH2) with text files instead of PaperUI. Below I will note how I'm changing my mind: Using PaperUI for some OpenHAB configuration & still using text files for other configuration.

At Location A, I've been using Arduino IDE 1.6.8 for the node programming.  I have not necessarily updated the supplemental libraries since I installed them.

As of Jan. 28, 2019, OpenHAB is up to a 2.5.0 snapshot, 2.1.5.M1 milestone, & 2.4.0 stable version.  Sounds like the Weather Underground service will soon not be available, at least on a cheap basis.  Other weather bindings & services are available.  Later OpenHAB 2 versions offer an embedded MQTT broker.

David_Graeff: "There were a lot of bug fixes recently for all bindings maintained by me which include the network binding, the hue emulation service and the mqtt binding. The “stable” 2.4 release will cause more issues than the milestone 2.5 build."

At another place I'll call Location B, in many ways, I'm starting fresh on a Windows 10, 64 bit laptop. In this thread, I will report what I try & my experiences.

        Arduino IDE & Libraries at Location B

At Location B, I installed Arduino IDE 1.8.8. Concerning libraries needed for the RFM69 Gateway & node choices options, I also installed the latest versions, confirming & documenting (in the sketches) the sources of where & how to obtain the libraries. I'm working my way through testing how each node choice option compiles.

So far the test compiles of the choose_nodes sketch are going well. The updated RFM69 library required the biggest changes, especially in relation to the wireless OTA programming for Moteinos & Anarduino Miniwireless Arduino compatibles (with installed RFM69 radios & flash memory). When I'm confident about the updated sketch, I will post it in this thread.

        Installing OpenHAB 2 at Location B

In this post, I reported that the official download site offers an intriguing UNofficial option for Windows: Install OpenHAB2 with Chocolatey. I believe that was the latest stable version (2.4.0). It came with Oracle Java 1.8.191. I was disappointed: OpenHAB 2 was buried at C:\ProgramData\chocolatey\lib\openhab\tools. (I moved all files to C:\openHAB2)  Oracle Java 32 bit installed, but 64 bit failed.

wwebers: "according to Oracle we will not get any public updates for their JDK 8 anymore."  ranielsen: Amazon looks like they are taking over from Oracle. They will be providing a supported versions of OpenJDK 8 for a few years: aws.amazon.com/corretto/

I experimented with OpenHAB versions from 2.4.0 down to 2.2.0, trying to configure with text files. I did not have much success, especially with 2.xx bindings (like ntp & network). Often (with no discernible help), I deleted the \userdata\cache & tmp folders to clear the cache. I experimented some with installing the embedded MQTT broker & was not confident with results. At the moment, I have a working (separate) Mosquitto broker service running.

Since text configuration files were mostly not working with the later OpenHAB 2 versions, I'm trying something else: I'm working on an OpenHAB 2.5.M1 (milestone) install. (I downloaded the .zip & extracted it to C:\OpenHAB2.) Before I ran start.bat, I still put configured addons.cfg & runtime.cfg text files into C:\OpenHAB2\conf\services. I used a .thing text file to configure for the network binding. From PaperUI's inbox, I accepted an ntp thing. I used text files to configure 2 items for network & 1 item for ntp (see below. I used PaperUI to link the items to the things. All three items report fine on the basicui sitemap.

The log reported: MQTT Service initialization completed & Starting MQTT broker connection 'mosquitto'   Later I will program an RFM69 Gateway & node & will confirm the MQTT connection is working via the MQTT 1.14.0.M1 binding.

        Adding RFM69 Gateway & Node

Using the sketch from here, I programmed a Gateway to use Network One. The Gateway immediately connected with my local network & MQTT / Mosquitto.

Using a sketch updated from the one here (with current libraries), I programmed an end Node 05 which combines this one with this one (using the DS18B option).

So this end node has a DS18B temp sensor on Arduino D3, a DHT temp/humidity sensor on D4, a push button on D8, & a solid state relay controlled by D9.

Configuration Text Files Connect the Above Node
        to OpenHAB 2.5.0.M1 / Mosquitto

I have several custom icons in OpenHAB's \conf\icons\classic folder, which include comfort_level.svg. (The other icons came with OpenHAB's install.)

        I have an .items configuration text file with the following entries:

Group Gateways // Gateways, Router

Switch Router_Active "Router [%s]" <network> (Gateways) { channel="network:device:192_168_10_1:online" }
Number RouterResponseTime "Router Response Time [%.2f]" <network> (Gateways) { channel="network:device:192_168_10_1:latency" }

Group Network (All)    // homeautomation.proboards.com/thread/51/force-update-item-openhab
Group Nodes (Network)   // Uptime, BATT_Voltage, SW_Version, RSSI

String Node5Rssi "Base_FR_05_RSSI (db)[%s]" <network> (Nodes) {mqtt="<[mosquitto:home/rfm_gw/nb/node05/dev02:state:default]", mqtt=">[mosquitto:home/rfm_gw/sb/node05/dev02:command:*:default]", expire="3m,Offline?" }

Number Node5Voltage "Base_FR_05_Volts [%.2f Vdd]" <battery> (Nodes) {mqtt="<[mosquitto:home/rfm_gw/nb/node05/dev04:state:default]"}

Number DS18_N05 "DS18_N05 [%.1f °F]" <temperature> {mqtt="<[mosquitto:home/rfm_gw/nb/node05/dev50:state:default]"}

        In my .things file:

Thing network:pingdevice:devicename [ hostname="192.168.10.1" ]

    Configuration Text Files Connect the Above Node
            to OpenHAB 2.5.0.M1 / Mosquitto

    I have a .rules config text file with this rule (combines temp & humidity items into one item).

rule BaseFR_Sensed
    when
        Item Temperature_Node05 changed or
        Item Humidity_Node05 changed or
        Time cron "0 0/1 * * * ?"
    then
        var Number T05 = Temperature_Node05.state
        var Number H05 = Humidity_Node05.state
        var Number H05_r = (Math::round(H05.floatValue))
        var Number T05_r = (Math::round(T05.floatValue * 10.0 ) /10.0)
        BaseFR_TH05.postUpdate(T05_r + "°F... " + H05_r + "% ")
end

// ======================================

        I have a .sitemap config text file like this:

sitemap My label="My House"

{
    Group item=Nodes label="__Node Health__" icon="network"
    Group item=Gateways label="__Gateways Info__" icon="signal"

    Frame {
Text item=Router_Active
Text item=RouterResponseTime

Switch item=Act_Node05 label="BaseFR05"

Text item=Temperature_Node05
Text item=Humidity_Node05
Text item=BaseFR_TH05
Text item=DS18_N05
        }

    Frame {Text item=Date}

}

    User Interface Results of the Above

The above programming & configuration (& the Mosquitto / MQTT connection) are working well. That includes the custom icon, which sometimes did not display with OpenHAB 2.1.0.

Besides the data shown on the User Interface (below), I can toggle the node's solid state relay on & off with either the node button or the virtual switch on the User Interface.

Update, Feb. 3, 2019:  In this thread, I document installing OpenHAB 2.5.0.M1, the Embedded MQTT broker, & the OpenHAB 2.xx Bindings: NTP, Network, AND MQTT 2.  I used PaperUI except for Items, Rules, & Sitemap.  This approach was more tedious than my previous (mostly text configuration) approach, but also went more smoothly than how the previous approach works now.

        Installing a Current OpenHAB 2 Continues
                A 2.xx Weather Binding

Until recently I've used the 1.xx Weather binding with data from Weather Underground. Above I wrote: "Sounds like the Weather Underground service will soon not be available, at least on a cheap basis. Other weather bindings & services are available."

OpenWeatherMap is weather data service with a nice free package AND OpenHAB offers a 2.xx OpenWeatherMap Binding. OpenWeatherMap offers most of the data types I was using before from Weather Underground & I could get some of the missing data types by calculating from what was available.

In another thread, I will document some of my experience with using the OpenWeatherMap service & binding.

        Updates on Latest openHAB Installs

For initial installs, I continue to use PaperUI to start configuring openHAB & then add text configuration files of items, rules & sitemaps.

Other than it's not using the latest version, I believe this thread on installing openHAB is still relevant. What that approach produced was still workable when I upgraded to openHAB2.5.0 stable & openHAB2.5.1 stable.

As this thread describes, I'm now installing/updating openHAB using very helpful scripts.
