Calculate traveltime

[mvrekum 2]

Hello, since I am not a programmer I have a question for the programmers on this forum. In the introduction video from Fibaro there is a scene where the travel time between 2 locations (i.e. where ever you are and home) is calculated. I know it is possible using google maps to calculate the travel time between 2 coordinates. See this example which calculates the travel time between two city centers by car:

for explanation of the parameters

Is there someone who is willing to write a script that pulls the location of a user from his phone and calculates the travel time to Home and store this in a variable to be used in other scripts as timer? Maybe it is even possible to recalculate the traveltime every 15 minutes if the original traveltime is more than 15 minutes, since the traveltime will change depending on how fast you drive

The goal is to start scenes when you are close to home, i.e. start the coffeemaker when you are 5 minutes from home.

I have been playing arround a bit and got this code so far in a virtual device button:

It is generating a response from Google, but I do not know how to get the duration value out of the response. Can anyone help? Please.

This is the response from Google Maps Api:

I tried with json.decode to retrieve the duration value "2451" (this is the travel time in seconds), but it just won't work. Can anyone show me the proper way to decode this?

Hello, great code!

Try replacing your last line with this:

That should do the trick!

Good luck!

@lundan: Thanks lundan. Yes, that did the trick. Now I can continue.

@stevenvd: Steven, I do not want to know the distance, I want to know the time it takes to travel that distance. I want to use that time as timer input to start scenes.

I.e. my heater takes about 30 min. to heat up the house (it's well isolated). It takes me about 40 min. to travel home from work at normal traffic. In case of traffic jams it can take over 2 hours to get home, like yesterday when the A50 was closed in both directions because of accidents. Yesterday it took me about 1.5 hours to get home. I can not tell the distance I have to travel when I am 30 minutes from home. For 200 meters your method is possible, but how about 30 km? A lot can happen in 30 km. If I used your method yesterday, my heater would have been running for one hour for no one. A waste of energy.

For those of you who want to experiment with it. Make a virtual device with just a label and put the code below in the main loop.

Now you can call the travel time value for use in your scenes with:

fibaro:getValue(123, ˝ui.Label1.value˝)

where 123 is the virtual device ID. You can find the ID in the address bar when you have opened the virtual device (should have been listed in the device panel like with all other devices!!).
