Virtual Devices on HCL, worthless without LUA ...?

[PeGe 8]

Hi,

 

On my HCL, I want to display some input values from my YouLess Energy Meter.

I tried a Virtual Device but this didn't succeed.

 

Does anyone have an example for how to use 'strings' in Virtual Devices?

 

(please no LUA, since only 'strings' are supported by HCL)

 

 

 

Thanks!

Anyone experiance with the use of 'strings' in Virtual Devices, please ?

I would like to bring it up + my question on the topic - how to use virtual device (in a more sophisticated way)?

Lack of LUA programming in HCL is a huge limitation. Is there any chance to use any coding in HCL at all?

[pejot 0]

to be more precise - will callAction allow me to do something similar to fibaro:setSceneEnabled(ID, false) ?

As far as I no... there's no way for coding in a HCL at all. So, I'm looking for ways to work arround this limitation and there are some thoughts I have that I would like to share here.

 

I have a Euro 9,- NodeMCU development board which is running LUA and it has several GPIO ports and there's an ESP8266 Wifi module on board.

So maybe it is possible to send 'strings' from this board via WiFi and my local LAN to Fibaro HCL Virtual Devices to control scene's etc.

 

However, right now I have no clue how to address the Virtual Devices using 'strings'.....

[PeGe 8]

I've had a new brainwave to work around the missing-LUA-on-HCL issue.

 

Now I'm thinking of installing node.js and use NodeRED on my Raspberry Pi. Using NodeRED it should be possible to interact with the HCL API.

 

Still need to find out how to use the HCL Virtual devices though....

Who can help me out with the use of Virtual devices using 'strings' , please..................?

Example of a string used for turning off a samsung TV.

sendir,1:1,1,38028,1,1,173,173,21,65,21,65,21,65,21,21,21,21,21,21,21,21,21,21,21,65,21,65,21,65,21,21,21,21,21,21,21,21,21,21,21,21,21,21,21,21,21,65,21,65,21,21,21,21,21,65,21,65,21,65,21,65,21,21,21,21,21,65,21,65,21,21,21,1832 0x0D0x0A

I've a virtual device with a label where I update "now playing" info for my music system. I'm doing this with a HTTP-call:

Update the IP to the IP of your HCL.

deviceID - The id of the virtual device

mylabelid - The id of the label in the virtual device

mystringvalue - Whatever string you want to send. Use %20 for whitespace.

 

To be able to do this, you need to set a request property "Authorization" to "Basic <your auth string>". Your auth string is a Base64 encoded string of your fibaro credentials. <user>:<password>.

 

An example admin:admin -> YWRtaW46YWRtaW4=

If you are already logged in to your HCL in your web browser, you should be able to just copy/paste the URL and it should work if you want to try it out.

 

Hope this helps.

KristianO and Hendrik: Thanks!

 

As soon as I have time to pick up this issue, I will respond in this topic with the results. (can take some time, need to move to a new house soon...)

Hi Henrik,

 

Thanks, your solution is working fine !

 

p.s.

In your signature I read this: " Fibaro Home Center Lite v4.058 Beta > LUA possible! "

Does this mean you have found a way to use LUA for HCL?

If so, please let me know how. Thanks!

Hi guys,

I connected a NodeMCU with just using a virtual device named NodeMCU with 2 buttons as follow:

1. Label: ON , ID: B1, code: /LED=ON

2. Label: OFF , ID: B2, code: /LED=OFF

 

The NodeMCU server window reported:

 

new client

GET /LED=ON HTTP/1.1

Client disonnected

 

new client

GET /favicon.ico HTTP/1.1

Client disonnected

 

new client

GET /LED=OFF HTTP/1.1

Client disonnected

 

new client

GET /favicon.ico HTTP/1.1

Client disonnected

 

 

.....and then....it suddenly stopped responding to the Fibaro buttons.....also the Fibaro SAVE button stays blue.....I have a feeling the Fibaro can't save the virtual button.

Please advice what went wrong?

I tried the nodeMCU via a simple http test and it works and switches the LED on and off, which means the Fibaro doesn't serve the communication. All other original z-wave nodes work as is.....

 

Thanks in advance

Nick

+.... some more info about the problem:

 

1. Fibaro HCL doesn't forward any data to NodeMCU IP via port 80 although the virtual device is properly set with IP address and port 80;

2. If port 80 tested via a browser, it provides communication with the NodeMCU.

! PROBLEM SOLVED !

 

A simple power disconnect for 10 seconds and then powering again the HCL fixed the issue.

It seems that a simple HCL warm reset is not enough ....... any explanations?

Hi, I hope your HCL will stay stable from now! Thanks for letting us know and please keep us informed here... thanks!

 

 

Could you please upload all the settings of your Virtual Devices please? (screen shots would be very helpfull to me)

 

Thanks!

Hi,

Hare is the info required:

1. NodeMCU settings:

Thanks a lot Nick!

This will give me jump start!

 

I also have problems with setting up the Virtual Device in my HCL.

Could you also please let me know the exact settings/ screen shots for this?

Thanks in advance!

Also you have to set static IP for your NodeMCU in your router.

 

....the only thing I have to find out is how to read NodeMCU data with Fibaro HCL ???????......anybody to help with??????????????

Hi Nick,

 

I was able to read values with my browser. Thanks to post #10 from Hendrik:

 

Please login or register to see this link.

 

 

Is this what you are looking for?

 

Did you also take care about the authorization string before trying to read values?

[nickarsow 3]

Hi PeterG,

Can you please guide me with a link or some explanations about using/writing the authorization string?

Thanks in advance

Nick

[PeGe 8]

Hi Nick,

 

I only tested this with my browser. To avoid authorization issues at that time, I also stayed logged in on the HCL with my browser.

This way the authorization string was not needed while I was testing. I know this is a bit simple and not usable for real, it's only for fooling around with value changes....

 

Somewhere I read about authorization using JSON on a HC2, perhaps it was on this forum. The following is what I saved to remember myself:

 

Authentication("admin","admin") response = HC2:GET("/api/settings/location") response = json.decode(response) response.ntpServer = "pl.pool.ntp.org"; response.ntp = true; local payload = response; payload = json.encode(payload) response, status, errorCode = HC2:PUT('/api/settings/location', payload)",
            "buttonIcon": 0,
            "favourite": false,

 

 

I guess this is for no use to you but perhaps it can be a start to find out more?

 

Or have a look at what Henrik said in his post #8:

 

To be able to do this, you need to set a request property "Authorization" to "Basic <your auth string>". Your auth string is a Base64 encoded string of your fibaro credentials. <user>:<password>.
