I've also tried the LUA variant but it's not working. Get the same message as others. Seems the call to waze is not correct and returns an empty result. But I didn't know how to fix.
I have it working with this url in the posted lua code:

Code: Select all

	local waze=assert(io.popen('curl "https://www.waze.com/row-RoutingManager/routingRequest?from=x%3A'..departx..'+y%3A'..departy..'&to=x%3A'..arrivex..'+y%3A'..arrivey..'&returnJSON=true&returnGeometries=true&returnInstructions=true&timeout=60000&nPaths=1&clientVersion=4.0.0&options=AVOID_TRAILS%3At%2CALLOW_UTURNS"'))
Also changed the LUA script to retrieve the travel time in both directions, update 2 devices in Domoticz and run it with crontab every 5 minutes, in stead of running this by the domoticz event system to avoid introducing delays in there.

Please...
One says LUA..
Other says PHP...
What option, and what is the best script...? :D :D

Depends on your needs and skills ;)
I like PHP, I entirely control Domiticz from it.
Many others prefer lua, alltough there are lot's of difficulties and shortcomings.

A simple working script..
That is monitoring waze...
Time = x between xy
Route = y to x or x to y
File = x
File = xxx switch domoticz IDX on

And that for multiple time's and multiple routes

You also want Mayo with that? :D

Here is my LUA version that handles 2 routes at this moment but easy to extent:

Code: Select all

-- file waze_get_travel_times.lua
-----------------------------------------------------------------------------------------------------------------
--
-- get the travel times via Waze for home-work and work-home and update 2 devices in Domoticz to track the times
-- copied the base code from domoticz forum member iero  http://www.domoticz.com/forum/viewtopic.php?f=23&t=7777
--
-----------------------------------------------------------------------------------------------------------------

function traveltime(departx,departy,arrivex,arrivey)
	--get route from WAZE--
	local waze=assert(io.popen('curl "https://www.waze.com/row-RoutingManager/routingRequest?from=x%3A'..departx..'+y%3A'..departy..'&to=x%3A'..arrivex..'+y%3A'..arrivey..'&returnJSON=true&returnGeometries=true&returnInstructions=true&timeout=60000&nPaths=1&clientVersion=4.0.0&options=AVOID_TRAILS%3At%2CALLOW_UTURNS"'))
	local trajet = waze:read('*all')
	waze:close()

	print("========================================================================================================")
	print(trajet)
	local jsonTrajet = json:decode(trajet)

	--Get major road from JSON
	routeName = jsonTrajet['response']['routeName']
	--Get route steps from JSON info
	route = jsonTrajet['response']['results']

	--Calculate the total time by adding the time of all sections
	routeTotalTimeSec = 0
	for response,results in pairs(route) do
	   routeTotalTimeSec = routeTotalTimeSec + results['crossTime']
	end

	--translate the number of seconds to minutes
	routeTotalTimeMin = routeTotalTimeSec/60-((routeTotalTimeSec%60)/60)

	return routeTotalTimeMin
end

--import JSON addin (already used with DTGBOT and stored in the standard library)
json = (loadfile "/usr/local/share/lua/5.2/JSON.lua")()
-- Update these variables ---------------
--idx of devices for capturing the travel minutes in both direction
idxhomework = '250'
idxworkhome = '251'
--coordinates Home
departy="xx.xxxxxxx"
departx="x.xxxxx"
--Coordinates Work
arrivey="xx.xxxxxx"
arrivex="x.xxxxx"
-- get travel time
homework=traveltime(departx,departy,arrivex,arrivey)
workhome=traveltime(arrivex,arrivey,departx,departy)
print("homework:",homework,"workhome:",workhome)
-- update Domoticz devices
url='http://192.168.x.xx:8080/json.htm?type=command&param=udevice&idx=' .. idxhomework .. '&nvalue=0&svalue=' .. homework
read = os.execute('curl -s "'..url..'"')
url='http://192.168.x.xx:8080/json.htm?type=command&param=udevice&idx=' .. idxworkhome .. '&nvalue=0&svalue=' .. workhome
read = os.execute('curl -s "'..url..'"')
.. and I run it with Crontab every 5 minutes:

Code: Select all

# get Home-Work travel times
*/5 * * * * sudo lua /home/pi/domoticz/scripts/waze_get_travel_times.lua > /var/tmp/waze.log

Jos and Iero thanks...!!!

I don not like Mayo..
Better a beautiful .... ;)

Only the script is a little bit the high maths for me....

I have to study for this..
So i give it a try..
When i got problems...

I be back

I want to send a notification when on a specific time the value of the pressure sensor > specific value.

For example:

Code: Select all

	--Check current traveltime
	if (uservariables['home'] == 'true' timeCurrent == '0705') then
		if (otherdevices['travelTimeHomeWork'] > 30) then
			commandArray['SendNotification']='Druk op de weg#Let op, langer dan gemiddelde reistijd. Huidige reistijd is: #0'
		end
	end
But I don't get the value of the sensor in LUA, somebody who knows how I can achieve this? otherdevices['travelTimeHomeWork'] > 30 is not working and I couldn't find the correct syntax for the pressure device and LUA.

Shouldn't that be something like:

Code: Select all

otherdevices_svalues['travelTimeHomeWork']
Not sure what exactly is returned for a pressure sensor, so you might want to temporarily add a print() to display the retuned value so you can see.

Thnx, that did the trick.

Final script for this one:

Code: Select all

--Set system variables
commandArray = {}
timeCurrent = os.date("%H%M")

	--Check if it's no holiday
	if ( uservariables['isHoliday'] == 'false' ) then

		--Check current traveltime travelTimeHomeWork
		if (uservariables['home'] == 'true' and timeCurrent == '0705') then
			if (tonumber(otherdevices_svalues['travelTimeHomeWork']) > 23) then
				commandArray['SendNotification']='Druk op de weg#Let op, langer dan gemiddelde reistijd. Huidige reistijd is: ' .. otherdevices_svalues['travelTimeHomeWork'] .. ' minuten #0'
			end
		end

		--Check current traveltime travelTimeWorkHome
		if (uservariables['home'] == 'true' and timeCurrent == '1640') then
			if (tonumber(otherdevices_svalues['travelTimeWorkHome']) > 23) then
				commandArray['SendNotification']='Druk op de weg#Let op, langer dan gemiddelde reistijd. Huidige reistijd is: ' .. otherdevices_svalues['travelTimeWorkHome'] .. ' minuten #0'
			end
		end
	end

return commandArray

You're welcome.

The code gives this as page:
Image

You'll notice that their is quite some hardcoded stuff in it. Like "if($tijd>4285) echo strftime("%k:%M:%S",$tijd-3600-4285);" shows the delay. 4825 is the 'normal' route time.
The usage of the function is "traffic($startlat, $startlon, $endlat, $endlon)"

I really like this idea! It inspired me to do the same with this page:
http://www.rijdendetreinen.nl/vertrekti ... /eindhoven (actual train departure times).

I will open a new topic if I have it successfully working, could take a while :)

For those who get the " attempt to index local 'jsonTrajet' (a nil value)" error, here some tips on windows platform :

1/ curl program must be installed and accessible. And a CRT certificate must be accessible to. (as the API is SSL). So I put the curl.exe and curl-ca-bundle.crt in the domoticz directory. (the one where domoticz.exe is)

2/ And be carefull for the path of the json.lua. Like this : json = (loadfile "D:\\Domoticz\\scripts\\lua\\json.lua")()

3/ FYI, x=longitude. y=latitude

I use a python script, It's works great.
I put this script in the crontab and run it every 5 min.

Code: Select all

#!/usr/bin/env python2.7

import RPi.GPIO as GPIO
import urllib2
import json

# Parametres
domoticzserver="192.168.0.20:8083"

#requete waze

print "home - work"
idx='113'
startlat='-----------'
startlon=''-----------'
endlat=''-----------'
endlon=''-----------'
extract_var = urllib2.urlopen("https://www.waze.com/row-RoutingManager/routingRequest?from=x%3A" + startlon + "+y%3A" + startlat + "&to=x%3A" + endlon + "+y%3A" + endlat + "").read()
#print "requete recuperee : ", extract_var
#extraction du temps de trajet
pos1 = extract_var.find('<summary time="')+len('<summary time="')
pos2 = extract_var.find('" length=')
pos3 = pos2 + len('" length="')
pos4 = extract_var.find('</route>') - 4
timesec = extract_var[pos1:pos2]
distance = float(extract_var[pos3:pos4])/1000
timesec=int(timesec)
print "Distance : ", distance, " km"
#print "Temps de trajet : ", timesec, " secondes"
timemin=round(float(timesec)/60,2)
print "Temps de trajet : ", timemin, " minutes", "     ==>  format a envoyer a domoticz"
print "Temps de trajet : ", int(timesec/60), " minutes", (float(timesec)/60 - int(timesec/60))*60, " secondes"

I guess they try to protect their service.
When I use curl instead of file_get_contents and add a Firefox user agent to it it works again.
