The DTGBOT is running a loop requesting the "getUpdates?timeout=60&offset=xxxx" status. This will wait for about a minute for incoming messages after which the connection is ended by the server. In case there is no message the request is simply done again.
In case a Telegram message arrives for the BOT, the call returns right away and the message is processed.
This is the basic process used to retrieve the messages for the BOT.
The alternative could be to have Telegram deliver the messages, but that would mean you need to open up a port on your firewall and NAT to your PI, but this isn't implemented.

Hi all

don't understand why, but dtgbot stopped working.
It worked well until some days ago, and now nothing...

I'm getting into the roomplan error, as explained in the last part of the wiki http://www.domoticz.com/wiki/Remote_Con ... legram_Bot

But I have four Roomplan defined, as I already did, and no change from when it was working.

I get exacting the same errors as descrobed in the Wiki.

I get also active(exited) when I check status

Code: Select all

What can I check?

Set the domoticz user variable TelegramBotLoglevel to 2, start dtgbot and show or PM the dtg.log and dtg.log.errors so I can see what is happening.

Hi jvdz

I created the uservariable TelegramBotLogLevel, since I haven't got it.

Code: Select all

TelegramBotLogLevel	Integer	2

I then reboot it and this is what I have in dtb.log

Code: Select all

I don't see any differences in the log with this uservariable set to 2 or without it.

ah, i see the debug logging is set later so that indeed doesn't give more information. guess that needs changing.
Could you provide the output for this URL:

Code: Select all

This is what I get:

Code: Select all

{
  "result" : [
     {
        "Devices" : 12,
        "Name" : "Meteo",
        "Order" : "2",
        "idx" : "x"
     },
     {
        "Devices" : 0,
        "Name" : "NAS",
        "Order" : "3",
        "idx" : "x"
     },
     {
        "Devices" : 6,
        "Name" : "Persiane",
        "Order" : "4",
        "idx" : "x"
     },
     {
        "Devices" : 7,
        "Name" : "Irrigation",
        "Order" : "5",
        "idx" : "x"
     }
  ],
  "status" : "OK",
  "title" : "Plans"
}

Thanks

Now I removed the NAS roomplan which has no devices inside, but no changes

Posted: **Thursday 26 May 2016 12:02**

Still doesn't make much sense as it seems the url does return what is expected, but the error indicates nothing is received.
I've proposed this update to the device_list_names_idxs function in dtg_domoticz.lua to avoid the error:

Code: Select all

function device_list_names_idxs(DeviceType)
  --returns a devcie idx based on its name
  local idx, k, record, decoded_response
  decoded_response = device_list(DeviceType)
  result = decoded_response['result']
  devices = {}
  devicesproperties = {}
  if result ~= nil then
    for i = 1, #result do
      record = result[i]
      if type(record) == "table" then
        if DeviceType == "plans" then
          devices[record['Name']] = record['idx']
          else
          devices[string.lower(record['Name'])] = record['idx']
          devices[record['idx']] = record['Name']
          if DeviceType == 'scenes' then
            devicesproperties[record['idx']] = {Type=record['Type'], SwitchType = record['Type']}
          end
        end
      end
    end
  end
  return devices, devicesproperties
end

You could change it for yourself, but I expect the menu to be pretty empty.

The strange thing is that it was working until one week ago.
I probably have updated something (for sure the Domoticz bet to the last one) and some packages in Raspbian, but not in dgtbot.
I've tried reinstalling it, step by step, but nothing changes.

I will try this afternoon your update...
Thanks

Posted: **Thursday 26 May 2016 12:27**

We can take this offline (in PM) and simply start step by step the debugging until we found the the reason, but you will have to make regular updates to the LUA scripts for this.

ok, thanks for your availability.

I will do it most probably starting tomorrow.

Hi Jos

I just tried the script update you propose and now it's working!!!!

Thanks!

What was the trick?

Posted: **Monday 04 July 2016 21:01**

Can you share the script update?
I have problems getting the DTGbot service up and running.

If I send "devices" I don't get any response or the services crashes

Posted: **Monday 04 July 2016 21:12**

Just go to post 168 of this 3d, it should be less than five post before your.

Posted: **Monday 04 July 2016 21:16**

The update to the original script is posted a few posts up, but in case you want to debug the setup, then simply change the Domoticz variable TelegramBotLoglevel to 2, restart the service and check both dtb.log and dtb.log.errors for any errors.

Hi everybody,
After a lot of reading, and trail and error I managed to get the control by telegram working.
Great work!!! very nice function.
However I have one question (I'm not a programmer at all).
I would like to send a http post command ( for wife acceptence) to my bot with a switch command to open my gates. Now it works with "On xxxxx" but ultimatly i would like to create a shortcut on the telephone to do this. I would appreciate if someone could help me. I have looked around but can't find a solution
Thanks

Hi,

I believe I have followed all installation instructions, however I cannot send any commands to the bot.

Sadly, I think you are right, I don't think it is possible to send a message as an http post command.

This is effectively a Telegram question and would not require any modification to allow dtgbot to do what you want to, if Telegram allowed it. It doesn't due to the security issues it would raise.

The bot sends a message effectively via an http post - so dtgbot sends an http post command to the Telegram api, which results in a message popping up in your Telegram client, but you can't send a http post command to the bot this way.

My only thought was whether you could have a bot that could send a message to another bot, but I don't think this is possible.

So rather than an http post command, you would need to code a Telegram client, which would be a single button on a phone.

jvdz is working on inline menus which while running in a Telegram client do present simple buttons to push.

Only ideas -
You could have a command that is causing a problem, so try increase the bot offset - http://www.domoticz.com/wiki/Remote_Con ... use_Errors

a bit further ..

Using the service won't work, but running interactively "lua dtgbot.lua" things start to work !

Need to find what the difference is ..
