React on RSS feed

[MatthijsD]

Hello!

Does anyone know if it is possible to use switches through a RSS feed?

Situation: I want to turn on lights as soon as a RSS feed gets a post with a specifiek strain of text.

Why: I'm a firefighter and I want to turn on certain lights as soon as I get a notification on my pager. Because the pager doesn't have a way to send anything, I want Domoticz to look at an RSS feed.

Can someone help me, or maybe even tell me to look in another direction than RSS?

[Westcott]

Python has an RSS feedreader library.
It seems to be possible in LUA as well, which makes integration easier.
How frequently would you want to check the feed?

[MatthijsD]

Thank you for your reply!

I'm running on Synology and would like to let it check every 5 seconds, only in a given timeframe.

[MatthijsD]

Still unanswered and unsolved!
If anyone can help me out, that would be great

This LINK should help you get started.
It is simular to reading from a json table which has many examples here on the Domoticz forum.

[MatthijsD]

My script skills are sadly, very rusty.
I looked at other options and got the idea to use IFTTT web, to open an JSON url for a switch as soon as there is a new post in the RSS feed.
This, now resulting in automatically turning on the lights as soon as my pager goes off. Awesome

Thanks for the tips!

Welke RSS feed gebruik je voor de meldingen?

Hello MatthijsD,

Can you please tell me how you fix it? I work also as a fire-fighter in Holland. Please contact me.

Ok, guys, I didn't realize it was for the P2000 stream.
This code might actually do what you need.
In it's current version it writes it's output to a text device and (as test, I do not live in Holland, I fitered on 'brand' in the URL and Amsterdam in the script. It also writes the detected CAP codes to another text sensor but you could for example have it flip a switch or start a scene on certen cap codes(you own personal or department code)

The code should be very straight forward and easy to customize to your needs.
Edit: I should mention this is dzVents (version from version 2.4 upward)

Code: Select all

return {
	on = {
		timer = { 'at every 3 minutes'},
		httpResponses = { 'P2000' } -- matches callback string below
	},
	
	execute = function(domoticz, triggerItem)
local sensor = domoticz.devices('P2000')
local currInfo = tostring(sensor.text)
local Csensor = domoticz.devices('CapCodes')
local CcurrInfo = tostring(Csensor.text)
		if (triggerItem.isTimer) then
			domoticz.openURL({
				url = 'https://p2000.phlux.eu/v1/event?query=Brand&limit=1',
				method = 'GET',
				callback = 'P2000'
			})
			--print('P2000 triggered by timer')
		elseif (triggerItem.isHTTPResponse) then

	local response = triggerItem
		if not response.isJSON then print('data is not jSon') end
		if (response.ok and response.isJSON) then
			--print('P2000 triggered by callback')
			tl = #response.json.events
			tc = 1
			 repeat
				local bericht = tostring(response.json.events[tc].title)
				if bericht ~= currInfo then
				    if string.find((string.lower(bericht)), "amsterdam") then
				       -- print('bericht gevonden: '..bericht)
				sensor.updateText(bericht)
				print('msg : '..bericht)				
					CE = #response.json.events[tc].capcodes
					ec = 1
					repeat
					 local CAPs = tostring(response.json.events[tc].capcodes[CE].capcode)
						 if CAPs ~= CcurrInfo then
						 --print('Capcode = '..CAPs)
						 Csensor.updateText(CAPs)
						 end
					 ec = ec + 1
				 until ec > CE
				 end
				end
				tc = tc + 1
			 until tc > tl

		end
			else
				print('**P2000 failed to fetch info')
			end
		
	end

Code removed to save space

When I go to the url mentioned in the script, I end up with a warning page from Chrome, and then a site about package and such.

[elmortero]

Hi EdwinK,
It seems that that site is down.

I did a quick search and following code should also do what you want:

Code: Select all

return {
	on = {
		timer = { 'every minute' },     --this might be to low..
		httpResponses = { 'Pdroid' } -- matches callback string below
	},
	
	execute = function(domoticz, triggerItem)
local sensor = domoticz.devices('P2000')
local currInfo = tostring(sensor.text)
local Csensor = domoticz.devices('CapCodes')
local CcurrInfo = tostring(Csensor.text)
--parameters to be set (or not, if you leave empty the results will not be filtered )
local capcode = '' --seems to work only if also regio of plaats is used
local regio = ''

local plaats = ''

			domoticz.openURL({
				url = 'https://www.alarmeringdroid.nl/api/livemon?dienst='..dienst..'&regio='..regio..'&capcode='..capcode..'&plaats='..plaats,
				method = 'GET',
				callback = 'Pdroid'
			})
		elseif (triggerItem.isHTTPResponse) then

	local response = triggerItem
		if (response.ok and response.isJSON) then

			tl = #response.json.items
			tc = 1
			 repeat
				local dienst = tostring(response.json.items[tc].dienst)
				local regio = tostring(response.json.items[tc].regio)
				local info = tostring(response.json.items[tc].brandinfo)
    				if info == nil then info = '-' end
        					local melding = tostring(response.json.items[tc].msg) --items[0].msg
        					local regio = tostring(response.json.items[tc].regio) --items[0].regio
        					local info = tostring(response.json.items[tc].brandinfo) --items[0].brandinfo
        					local lat = tostring(response.json.items[tc].lat)
            				local lon = tostring(response.json.items[tc].lon)
        					local grip = tonumber(response.json.items[tc].grip)
        					local composed = tostring(melding..' ** '..info)
        					     if composed ~= currInfo then
        					      sensor.updateText(composed)
        						  print(composed)
        						        if lon ~= nil then
                						local google = ('https://www.google.com/maps/search/?api=1&query='..lat..','..lon)
                						print(google)
                						end
        						 end

        						tc = tl -- this is to limit the result to only one event. That should do if you set your filters correct
									-- if you want more results comment the line
    					--end
					tc = tc + 1
				 until tc > tl
			end
				else
					print('**Pdroid failed to fetch info')
				end
			
		end
	}

The info about filtering is in the script. If you leave the filter empty it will just be ignored in the URL. I recommend to use as much filtering as possible to make the json smaller (and thus load faster) so there is little chance of missing the alerts you want.
If you don't want the link to google maps (in this script only written to the log) remove lines 50 to 53

What am I doing wrong?

I tried to run this script but it didn't work. I made the 2 dummy text sensors named "P2000" and "CapCodes" but they were not filled with text.

Below is a part of my logfile:
2019-03-17 23:07:00.231 Status: dzVents: Info: ------ Start external script: Domoticz-P2000.lua:, trigger: every minute

I don't know how to check what I am doning wrong, if I put the text string direct in a Webbrowser it works normally, like a collection of text

Thanks for help!

Hi,
Maybe post your complete code, you might have added a non working filter since you do not get errors from dzvents.

[clut]

OKe, here is my code:

		end
	}
	

The file is saved under: ~/domoticz/scripts/dzVents/scripts as "Domoticz-P2000.lua"

Thanks for help!

[elmortero]

In order to check if it gets any data at all:
move line 49, the one that says print(composed) and put it before line 47 (if composed ~= currInfo then) so that the output is written to log without checking if it is different from the already stored text.
Also: change timer = { 'every minute' } to timer = { 'every 3 minutes' },

Let us know what happens in the logs

[clut]

Thanks for your reply, result looks like the same... I did what you suggested

And if I put the string direct into a webbrowser I do have the result below:
https://www.alarmeringdroid.nl/api/live ... =Amsterdam

[clut]

Is there maybe another method to find out what is going on? I mean, for some reason I do not have an error, but there is nothing dropped in my sensors so what am I doing wrong?

Hi Clut,

Sorry for the late reply. I don't use the script myself so lost track of the topic.
The issue is that alarmeringdroid does not have it's page headers correct (basically says the content is test instead of json).
I have my own way of solving that and my script relies on that.

The adapted code below checks for that and converts the data to correct json result.
Please have a try, if you still need this.

Code: Select all

return {
  on = {
    timer = { 'every 2 minutes' }, --this might be to low..
    httpResponses = { 'Pdroid' } -- matches callback string below
  },

  execute = function(domoticz, triggerItem)
    local sensor = domoticz.devices('P2000') -- You will need to have a text sensor called P2000
    local currInfo = tostring(sensor.text) -- gets the content of above sensor (so we won't update it with same content)

    -- set the next to parameters to filter results
    local capcode = '' -- seems to work only if also regio of plaats is used
    local regio = ''
    --[[ Possible values for regio are
			  1=Amsterdam-Amstelland 6=Brabant Noord 11=Brabant Zuid-Oost 12=Drenthe 27=Flevoland 7=Friesland 8=Gelderland-Midden 13=Gelderland-Zuid 19=Gooi en Vechtstreek 2=Groningen 25=Haaglanden 5=Hollands Midden 17=IJsselland 9=Kennemerland 15=Limburg-Noord 21=Limburg-Zuid 26=Midden- en West Brabant 3=Noord- en Oost Gelderland 24=Noord-Holland Noord 10=Rotterdam-Rijnmond 23=Twente 18=Utrecht 4=Zaanstreek-Waterland 20=Zeeland

      })
    elseif (triggerItem.isHTTPResponse) then

      local response = triggerItem

      if (response.ok) then
        if response.isJSON then -- check headers if "Content-Type => application/json" (alarmeringdroid does not)

            end
          end

          tc = tl -- Voids the next line to limit the result to last event only. If you want all results comment out this line
          tc = tc + 1 -- increase the counter with 1 in order to get the next (or better, previous) message
        until tc > tl
      end
    else
      print('**Pdroid failed to fetch info')
    end

  end
}

Hope it works for you now.
