Traffic with Google Maps in Domoticz

[Westcott]

Use the "value" which is in seconds and divide by 60?

Your route won't work here in the UK, the A4 and A7 are 450km apart...

Hi, i tried your new script !
it's working but the instructions about the traffic is in italian ?
anyway it can be in French for example ?

You mean the Message in Text box or in Telegram?

You can change as you want, just translate text in the script...

[woody4165]

There's a bug when the time exceeds one hour.

Google API output:

I couldn't find a solution yet. If anyone else has an idea? Much appreciated!

Correct and thanks.

I was grabbing the text thinking only on traffic minutes, not hours!

I've changed the code like this, taking the value instead of text and rounding the duration

Code: Select all

    -- Read from the data table, and extract duration and distance in value. Divide distance by 1000 and duration_in_traffic by 60
    distance = gmaps.routes[1].legs[1].distance.value/1000
    duration = gmaps.routes[1].legs[1].duration_in_traffic.value/60
    summary = gmaps.routes[1].summary
    mins=math.ceil(duration)
    -- mins round the duration

Here is the complete script modified.

Hi,
I've been trying this handy script... well done and thanks!

When I updated to the latest script my original dummy/custom sensors where "time to work" and "time to home" both with axis label minutes. With the new script, I set the 1st as idxtraffic and 2nd idxroute but both just show "18 mins" but I get

Code: Select all

 2016-04-18 11:15:00.878 LUA: 18min to go to the office at 11:15 route Lynn Rd 

in the log.
Any ideas?

[woody4165]

Are you getting traffic data from and to work at the same time? Meaning that you changed some working hours in the script?

The script was intended to get data from home to work at a certain hours and from work to home at other ones.

Don't know if this is the case.

[blackdog65]

Hi Woody,
Thanks for the quick reply.
Yeah I did alter the times as my travel times are different, but also I'd like to temporarily extend the hours for testing.

How should I set the

Code: Select all

--determine time (7:00-9:00, 16:00-19:00)
if ((time.hour > 6 and time.hour < 9) or (time.hour == 9 and time.min < 1)) then
    mattina=true; sera=false
elseif ((time.hour > 15 and time.hour < 19) or (time.hour == 19 and time.min < 1)) then
    mattina=false; sera=true
else
    mattina=false; sera=false
end

So that I could run it (for testing) 07:00-12:00, 13:00-19:00 without breaking it?

I currently have

Code: Select all

--determine time (7:00-12:00, 13:00-16:00)
if ((time.hour > 6 and time.hour < 12) or (time.hour == 12 and time.min < 1)) then
    morning=true; will_be=false
elseif ((time.hour > 12 and time.hour < 16) or (time.hour == 16 and time.min < 1)) then
    morning=false; will_be=true
else
    morning=false; will_be=false
end

Thanks,

Sean

[woody4165]

The Google API call is made within a function that is called in both case, home->work and work->home, and in both cases it return to the same variable.

Try to change this

Code: Select all

      --send message if traveltime is longer than usual
      if(traffic > usualtimehomework) then
        os.execute('curl --data chat_id=2285843 --data-urlencode "text='..message..'"  "https://api.telegram.org/bot196378808:AAFq49rg69CYODb2CBMBfLmKskseZCAvemA/sendMessage" ')

      end
        --return a text to the device (eg. 12 mins)

        commandArray[1]={['UpdateDevice'] =idxtraffic..'|0|' .. tostring(traffic)}
        commandArray[2]={['UpdateDevice'] =idxroute..'|0|' .. tostring(message)}
    end

        --return a text to the device (eg. 12 mins)

        commandArray[1]={['UpdateDevice'] =idxtraffic..'|0|' .. tostring(traffic)}
        commandArray[2]={['UpdateDevice'] =idxroute..'|0|' .. tostring(message)}

    end
 

into this

    --every 5 minutes
    if((time.min % 5)==0) then
        traffic_Home2Work=traveltime(fromx,fromy,tox,toy)
        message=tostring(traffic_Home2Work)..'min per andare in ufficio alle '..("%02d:%02d"):format(time.hour, time.min)..' percorso '..tostring(summary)
      --send message if traveltime is longer than usual

        commandArray[2]={['UpdateDevice'] =idxroute..'|0|' .. tostring(message)}
    end

--weekday (Mo-Thu) and time between 16:00-19:00

    --every 5 minutes
    if((time.min % 5)==0) then
        traffic_Work2Home=traveltime(tox,toy,fromx,fromy)
        message=tostring(traffic_Work2Home)..'min per andare a casa alle '..("%02d:%02d"):format(time.hour, time.min)..' percorso '..tostring(summary)

        commandArray[2]={['UpdateDevice'] =idxroute..'|0|' .. tostring(message)}

    end

In changed the variable "traffic" into "traffic_Home2Work" in the morning part, and "traffic" into "traffic_Work2Home" in the afternoon part.

Try this. If it's ok, I will made this change in the script and post it fully.

Hi, i tried your new script !
it's working but the instructions about the traffic is in italian ?
anyway it can be in French for example ?

You mean the Message in Text box or in Telegram?

You can change as you want, just translate text in the script...

thanks i just did

[blackdog65]

Hi Woody,
The script runs, noted in log, but seems to be frozen at "18Mins" with no further route info.

[woody4165]

Hi Woody,
The script runs, noted in log, but seems to be frozen at "18Mins" with no further route info.

Where is freezing, can you show the log and the part of the script you think is causing this?

[EBOOZ]

There's a bug when the time exceeds one hour.

I was grabbing the text thinking only on traffic minutes, not hours!

I've changed the code like this, taking the value instead of text and rounding the duration

Thanks, woody! Works like a charm

[blackdog65]

Hi again Woody,
Sorry for the delay, I had an emergency trip to London hate the place

So, here's my log output, note there is now no route info as before.

But I have found that my sensors were not frozen but since the code change at 1300 yesterday there has been minimal movement.

graph.png (26.3 KiB) Viewed 3526 times

My big worry is that my sensors look like this,

sensors.png (17.02 KiB) Viewed 3526 times

with no reference to "route"
Am I doing something wrong?
Sean

[woody4165]

Hi Sean

I think we have to distinguish two things.
Are these sensors text or what?

I'm using beta Domoticz and using a Custom sensor to get minutes number (and get graph) and a Text sensor to have the same text I'm going to send via Telegram, with the route.

So, if you want to get both information you get two choices:
you are on stable version (and you don't have Custom Sensor) or you don't need/want graph, you need to create two text Sensor and put there the complete text using something like these that you can find in my script published before:

Code: Select all

message=tostring(traffic_Home2Work)..'min to go to office at '..("%02d:%02d"):format(time.hour, time.min)..' route '..tostring(summary)

if you want Custom Sensors to have also graph you can create either only two sensors, one Custom and one Text and use it for Home2Work and Work2Home, since they are in different hours, or either create two couple of sensor like before and get information separated.

Hope I haven't confused you more...

In any case, if you post your script I can take a look into it...

[blackdog65]

Yay! I have it! I had 2 custom sensor. I changed it to one custom and one txt and it works perfectly.

Many thanks Woody, I hope I can help you one day

[woody4165]

No, problem. We are here to help each other!

[sj3fk3]

Yes, don't use the text but use the value and just divide by 60 to get minutes..

Hi all,

I am struggling a bit with this script..
Getting the following error:

Problem seems to be line 55 .. which is..

distance = gmaps.routes[1].legs[1].distance.value/1000

So i suspected something is wrong with the url on line 49.. so i executed this in the browser and without any error..

It's really strange...

I just test it moving just the json part to another script and I have like this:

Code: Select all

    --import JSON.lua library
    json = (loadfile "/home/pi/domoticz/scripts/lua/JSON.lua")()

    -- get data from Google Maps and decode it in gmaps
    local jsondata    = assert(io.popen('curl "https://maps.googleapis.com/maps/api/directions/json?origin='..fromx..','..fromy..'&destination='..tox..','..toy..'&departure_time=now&key='..key..'"'))
    local jsondevices = jsondata:read('*all')
    jsondata:close()
    local gmaps = json:decode(jsondevices)

    -- Read from the data table, and extract duration and distance in text
    distancet = gmaps.routes[1].legs[1].distance.text
    distance = gmaps.routes[1].legs[1].distance.value/1000

    duration = gmaps.routes[1].legs[1].duration_in_traffic.text
    
    
    print("distance "..distance.." distancet "..distancet.." duration "..duration)

And all is working fine...

what if you print just jsondevices to see if there is something before decoding, just like this

Code: Select all

print(jsondevices)
