[SOLVED] Send multiple channel tv to broadlink throu to only one rule

Setup, Configuration and Use Scripts & Rules
, ,
1

hello everyone good night I have made the following rule to control multiple television channels through broadlink,

I use DIRECTV and has declared approximately 40 television channels as Switch, when it is activated the code or channel number is sent to a rule which sends number by number to the broadlink

example TV channel MTV = 1334

sendCommand(One_DirecTv, ON)
sendCommand(Tree_DirecTv, ON)
sendCommand(Tree_DirecTv, ON)
sendCommand(Four_DirecTv, ON)

the problem is that the programming guide of my television is more than 200 TV channels for each television decoder or for each DIRECTV in my house I have 3 televisions and this generates a rule file of more than 9000 lines of code and 600 rules for each channel and that can make me independent of each of the 3 encoders

this works for me, the problem is that I have a rules file that is too large and when the raspberry restarts it takes approximately 45 minutes to load

this is my configuration

I have seen an example in this community where they use toString.substring (0, 1) to create a single rule in which it receives the command in string and then separates it and sends data by command data but it has not worked for me

rule "SEND COMMAND ONLY ONE RULE"
when
    Item Channel_select changed
then
    if (Channel_select.state == "NULL") return; // If NULL do nothing
    var topic = "broadlink/televisor/saladirectv/" + Channel_select.state.toString.substring(0, 1)
    publish("mosquitto", topic, "play-780f77b943fb")
    createTimer(now.plusSeconds(1)) [ |
        topic = "broadlink/televisor/saladirectv/" + Channel_select.state.toString.substring(1, 2)
        publish("mosquitto", topic, "play-780f77b943fb")
    ]
    createTimer(now.plusSeconds(2)) [|
        topic = "broadlink/televisor/saladirectv/" + Channel_select.state.toString.substring(2)
        publish("mosquitto", topic, "play-780f77b943fb")
    ]
end

in this example I base myself to try to reduce my code but it didn’t work for me

https://community.openhab.org/t/solved-channel-select-with-broadlink-and-mqtt/56680/2

can someone help me or give me an orientation

2

Yes because the MQTT action doesn’t work like this anymore:

I’m doing the following test

Sitemap

Switch item=Channel_select  label="Channel"  mappings=[112="112", 111=" 111 ", 114="114"]  icon="suenos"

Items

Number          Channel_select       "Channel select"

}
  }

Rule

import java.util.HashMap
import java.lang.String

rule "Tvswitcher"
when
    Item Channel_select changed
then
    if (Channel_select.state == "NULL") return; // If NULL do nothing
    val topic = "broadlink/televisor/saladirectv/" + Channel_select.state.toString.substring(0, 1)
    actions.publishMQTT("mosquitto", topic, "play-780f77b943fb")
    createTimer(now.plusSeconds(1)) [ |
        topic = "broadlink/televisor/saladirectv/" + Channel_select.state.toString.substring(1, 2)
        actions.publishMQTT("mosquitto", topic, "play-780f77b943fb")
    ]
    createTimer(now.plusSeconds(2)) [|
        topic = "broadlink/televisor/saladirectv/" + Channel_select.state.toString.substring(2)
        actions.publishMQTT("mosquitto", topic, "play-780f77b943fb")
    ]
end

in the sitemap of when I press any of the channels that are in the mapping, it sends its value to the variable or to the Item called Channel_select once it receives the value the rule is activated.

in the Log it shows me that the Item receives the value

==> /var/log/openhab2/events.log <==

2019-09-27 09:08:19.128 [ome.event.ItemCommandEvent] - Item 'Channel_select' received command 114

2019-09-27 09:08:19.147 [vent.ItemStateChangedEvent] - Channel_select changed from 111 to 114

but I get the following error

2019-09-27 09:09:26.680 [ERROR] [ntime.internal.engine.RuleEngineImpl] - Rule 'Tvswitcher': An error occurred during the script execution: index=0, size=0

can you help me, I would like to know what could be happening because I guess the digits are not separating me, because at least I think so

This is similar to what I did, as a challenge, here: Loop of flashing light inside a timer. This might be useful.

The error is complaining about the calls to substring. It’s telling you that Channel_select.state.toString is the empty String. Log value of Channel_select.state.toString and follow the state changes to that Item in events.log to see whether, when, and why it’s being set to the empty String.

5

i cant understand you… i see the example but i dont know how do it

6

I don’t know how to say it any simpler.

The empty String is a String with no letters.

The Item Channel_select is being set to the empty String.

There is no substring(0, 1) on a String with no letters.

You do not expect Chanbel_select to be the empty String.

Your team is to figure it why the Item is being set to the empty String.

7

I think I understand what you want to tell me is that I am only sending to the item a type of data in number format, so the tostring cannot separate the data since the type of data or information that is being received is type is not a string

8

Nowhere did I say anything about numbers.

If you log Channel_select.state.toString you will sometimes see that it is blank.

I already solved the problem … and I could make it work … the solution was none of the above …
