I’m happy to announce the beta version of the gtfs realtime component I have been working on. I’ve been using it with my local GTFS feeds for several months now with now issues. The component along with installation instructions are available on github.
I’d love to hear any feedback, and about good gtfs feed sources. If you have trouble finding the feed for your local area, feel free to post, and I (along with others) will try to help.
hey im glad you were able to get this as a component. your github readme says that the stopid and the route are optional, however both were required for it to get this far. i’m now getting an error on startup. looks like an import error, see last line.
heres my yaml:
- platform: gtfs_realtime
trip_update_url: 'http://www.vre.org/gtfs-realtime/TripUpdateFeed'
vehicle_position_url: 'http://www.vre.org/gtfs-realtime/VehiclePositionFeed'
departures:
- name: Leeland Rd to Alexandria
route: 2
stopid: 0000000000000000000000000000000B
and my error:

Rather than show the “time until” the next train/bus will arrive can you instead show the expected “arrival time” for example just 2:32pm?
That’s a really good idea, and it would definitely made sense to change that - I haven’t been actively working on this for a while, but feel free to submit a pull request if you have time.

Worked once (I think by mistake) but after a reboot it never showed again and came up with these error messages…
I am on a completely clean install of 0.53.1 and still no chance. @tom can you please explain how you got it to work?

So I dug into this like a mad dog and got it to work by doing this
- platform: gtfs_realtime
trip_update_url: 'http://gtfs.ovapi.nl/new/tripUpdates.pb'
vehicle_position_url: 'http://gtfs.ovapi.nl/new/vehiclePositions.pb'
Problem I now have or noticed is that this component is not timezone aware.
How to make it so?
My bus times shown are exactly one hour behind. Everything else works correct.
As you can see I have the HA display the current time which it takes from the RPi which it runs on.
Timezone is set exactly right on the device (also NTP for time sync) and in the configuration.yaml.
time_zone: Europe/Amsterdam
Suggestions?
Hi @dennisaion, did you ever figured this out? I’d like to display some cards with departure times in Hass but have no idea where to start…
I wanted to get this working with the Transport for NSW real-time GTFS for Sydney, but that requires authentication with an API key. So I’ve forked this component, adding an optional api_key parameter. I’ve also started to add some more error checking and logging, which should hopefully shed some light on the root cause of most of the “Tag had invalid wire type” errors, or at least the ones I experienced.
Not sure about the timezone issues though. Presumably Europe/Amsterdam was at UTC+1 at the time. All I know for sure is that the TfNSW feed I’m looking at shows start times in localtime without an offset. It looks like the code assumes that will be case, so if a feed is sending times in UTC they’ll end up being displayed in UTC.
Anyway, if anybody is interested, my fork is currently at https://github.com/phardy/hass-gtfs-realtime
Im trying to find URLs for NYC MTA Subways. I can find their real time GTFS data but I do not see any urls for the train positions etc. What do I do?
Does this still work? I followed the instructions and it can’t find the component. Might be because I’m running hass.io?
I was able to get a little farther. Seems like the file structure has changed, I had to change Sensor/ to gtfs_realtime/ and gtfs_realtime to sensor.py. I also added a blank init.py. Now i’m getting this error which seems similar to the errors above
