2017-07-20 15:15:00.589 Error: EventSystem: in Enigma: [string "-- This script is used in conjunction with En..."]:136: bad argument #1 to 'sub' (string expected, got nil)

[lonebaggie]

Maybe a bug . Put the following characters into EnigmaStatus user variable 1|1

[Gelo5]

YES YES YES!!!!!!!!!!!!! but...... the data don't change on the desktop. Still OFF (Stutus, Programs)
Restart system an BINGo!!
Thank you for the help. Everything works!!!
This is my first Lua. I'm using Python.
THANK YOY VERY MUCH! Dziekuję.

[lonebaggie]

Good News . The EnigmaStatus should show if the box is on or off and channel currently being Viewed. I will fix the bug . Cannot manipulate strings in LUA if they are blank !!

[Gelo5]

Script does not see "+". For example Canal + HD, Planete+ HD, Canal+ Film HD etc...

EngmaList: CANAL+ HD
EnigmaStatus: f|CANAL HD

2017-07-20 17:47:00.607 LUA: EnigmaChannel is CANAL+ HD
2017-07-20 17:47:00.607 LUA: Channel changed to CANAL+ HD
2017-07-20 17:47:00.616 LUA: No Switch List Update
2017-07-20 17:47:00.732 LUA: Enigama Scan Start
2017-07-20 17:47:00.732 LUA: Channel CANAL HD not known

[Gelo5]

Last Beta (8197) does not update the switch status.
Edit:
Next Beta 3.8199 - Works again!

[lonebaggie]

yes bug in adding + to user variable Cannot add + via user interface or API. Can add + via LUA looking at issue

[Gelo5]

I resolved the problem by removing "+" from the list of programs. Instead Canal + HD is Canal HD etc ..

[lonebaggie]

fixed the bug its an issue with html same with spaces

Code: Select all

-- This script is used in conjuction with Enigma-Scan to maintain selector switch status with Enigma 2 settop boxes
--
-- This scripts scan the enigma 2 box to obtain current device state, and current current channel being views.
-- These  are stored in the EnigmaStatus user variable. 
--
-- This script  relies on a least 2 virtual switches being created an on/off switch (to turn on/off the Enigma2  box) and a selector switch.
-- Each selector switch and the off/on switch  must be pre-populated  with  the correct TV channels names  and action URL.
--
-- ********Setup Selector Switch Instructions**********
--
-- Run the following HHTP call against the Enigma2 set-top box will  obtain the correct information to populate the selector switch.
--
-- http://192.168.1.99/web/getallservices (where 192.168.1.99) is IP address of the Enigma 2 Box
--
-- This will return a complete list of all channels the Enigma 2 box recognises. 
-- Note the following information :-
--               <e2servicename>  
--               <e2servicereference> that matches the <e2servicename>. 
--              
-- Note due to limitation of selector switches they can only hold 10 levels. So create as many selector switches as required. 
-- Each selector switch can hold a different category of Channels Entertainment, MOvies , Music , etc.
--
-- The Selector level  in the selector switch must match the <e2servicename>  exactly.
-- The Selector action in the selector switch uses the following syntax http://192.168.1.91/web/zap?sRef=<e2servicereference>.
-- 
-- *********Setup On/Off switch instructions **************
--
-- to turn the Enigma2 box :-
--
--on            http://192.168.1.99/web/powerstate?newstate=4 (where 192.168.1.99 is the IP address of the Enigma2 box)
--off           http://192.168.1.91/web/powerstate?newstate=5
--
--
--
-- The script will also automatically  populate the EnigmaList(n) user variable(s) with the selector levels in the selector switch(es) created above. 
-- One EnigmaList(n) user variable for each selector switch created above.
--
-- The following user variables must be created before the script is run.
--
-- EnigmaParams  Multiple values to hold IP and switch details. Each value is  separated  by a |. 
--               The position in the parameter list determines the role of the value.
--
--               1 = * This is an optional value . If present will cause the script to delete and recreate the data
--                     in EnigmaList(n) user variable(s). Once updated the script will remove the "*" .                 
--               2 = Ip address of Enigma2 Box 
--               3 = On/Off switch IdX
--               4+ = IdX(es) of selector switch(es) which hold channel list. One list for each switch value specified.
--
--               Example 192.168.1.99|45|47|49|50 
--               Ip address,IdX of on/off switch that control Enigma2 power state,Idx of selector switches
--
--               Example *|192.168.1.99|45|47|49|50 as above but will cause EnigmaList(n) values to be regenerated 
--            
-- EnigmaList(n) Multiple variables to hold individual selector switch LevelNames. 
--               One User variable must be created for each selector switch defined.  
--               This is popuated by this script. 
-- EnigmaStatus  This holds the state of Enigma2 box and the current channel being viewed.Each value is seperated by a "|"
--               f = not in standby. t = is in standby
--
-- User variables are updated in a way other that other scripts (Enigma-Scan) can be triggered if any of the uservariables change.
-- If the EnigmaParams user variable is edited to start with a "*" this will trigger this script to update EnigmaChannel(*) with the 
-- contents of the selector switches defined above.

[lonebaggie]

Make sure your level names and Idx numbers match your selector switches the error is in the code that updates the enigma lists . It is only called when you have * in the enigma params variable. I suspect you need to put the + back into your selector switch names

[Gelo5]

I changed the IP address from 192.168.1.254 to old 127.0.0.1 (line 171 and 178) in the script. And it works!!!! Sees the "+" sign. I do not know why but it works !!
Thank you for your hard work in making the script.

[lonebaggie]

IM an idiot . Testing with my IP address. 127.0.0.1 is a loopback address. So will work whatever you set Domoticz IP address to . Glad you worked it out. Will change the source. Thank you

[mvroosmalen]

Hi,

I have two questions:
1) I want to use two lists, one for radio and one for TV. will this work?
2) within one of the programs a % sign is used and seems to block the system, is that seen before (maually entering this in variable is not allowed)
(name is 100% TV)

Hope you can help me out.

Thanks

Mark

[lonebaggie]

Yes you can have two lists radio and TV. As long as the selector lists match the enigma should be OK. The % in the station name is causing a bug . I will see if I can fix

[lonebaggie]

Try this the % same error as the + and the space

Have just added another string substitution to allow the % to be parsed correctly in the HTML call back to Domoticz user variable . Note the double %% as % is an escape character

Spoiler: show

TChannel=string.gsub(TChannel, "%%", "%%25")

Let me know if this works have no TV listing in the UK with % in the title to test

[mvroosmalen]

Thanks

The problem is that Domoticz doesnot accept % in the UserVariables so I replaced the % by _ and using:
TChannel = get(row[5],"e2servicename")
TChannel=string.gsub(TChannel, "%%", "_")
in the Enigma lua script. I need to change the script so it fill the UserVariables without %...

Update:
Added additional code between (bold)
Level = SwData["result"][1]["LevelNames"]
Level = string.gsub(Level, "%%", "_") --Replace % by _
Var = ("Variable:EnigmaList" .. (i-3))
This solved the % problem for domoticz


Mark

[lonebaggie]

Glad you got it working. I also had issues with the User-variable interface in Domoticz not accepting certain escape chars.

Im looking at converting these scripts to DzVents .As DzVents has it own Global variables.

[kofec]

If some want. Ihave created python plugin for Domoticz. Any comment are welcome.

https://github.com/kofec/Domoticz-Enigma2

[mvroosmalen]

Hi
Tried to install https://github.com/kofec/Domoticz-Enigma2, but Domoticz-Enigma2 is not present in the list of hardware??? Installed Python-3 (both) and tested with latest beta....3.8775.

Any idea's?? The log doesn't show any errors or warnings.

Its now visible as Enigma2 with kodi remote?? is this correct?

the following errors are noted:
2017-12-10 20:54:26.838 Error: (Enigma2) failed to load 'plugin.py', Python Path used was '......domoticz/plugins/Domoticz-Enigma2/:/usr/lib/python3.4/:/usr/lib/python3.4/plat-arm-linux-gnueabihf:/usr/lib/python3.4/lib-dynload'.
