Home Assistant with Dublin Bus RTPI

matrim

For anyone interested I've written a home assistant component that links with the Dublin Bus real time information. It will give you the time in minutes to the next bus and you could use this to trigger automations, e.g. change a light to let you know it is due.

This was released as part of the new home assistant 0.36 update that was out today. For more information see https://home-assistant.io/components/sensor.dublin_bus_transport/

I hope us HA users aren't adding too much to the load . IIRC it's one request per configured bus per minute.

Yes, it is every minute. Builds up if you're using multiple stops/configs, then lord knows how many users use HA

They said they were getting tens of thousands of requests an hour which was putting the server under strain, even running through the night (out of bus service hours).

I would assume myself it's all the 3rd party phone apps (Dublin Bus app is AFK) that you can hit refresh a thousand times a minute to find that ghost bus

I got a swift reply, it seems the API is overloaded and thus has been temporarily restricted for some time. There's going to be a new server rollout in the coming weeks that can handle the larger load seen recently.

Ok. You could try emailing them. I did last year when they had a certificate issue and they were very responsive and helpful.

Yep way ahead of you

Will let you know

Understood but making API HTTP requests directly, the API server itself responds with 503s quite often

It seems the dublinked API is wholly unreliable these days.

I have a fix coming in the next version that should hopefully make the home assistant checker more stable. Basically I wasn't checking that the 2nd bus time was always being set and this was throwing an error which could cause home assistant to stop checking the API. I think the next release is due tomorrow.

This is possibly the same issue that people were getting for a while. I recently changed office so re-setup the bus checker and now use it enough to actually get to the root cause of the issue.

Same with me. All errors have disappeared relating to this one.

Now I just need to fix the others that have been on my to-do list.

cherryghost

Well, I've dug into my logs and the error magically stopped for me at 5:20 this morning, all has been working since then. No idea what triggered it to stop as I was fast asleep at that point!

Yep same here. I'm on the latest Hass.io install since last night and the bus component is throwing out same errors.

Is still showing the correct data I assume tho as I'm still getting bus times.

Are you using any custom UI elements or custom written scripts?

cherryghost

It's not working at all for me. I'll have a look at the script myself later to see what may have changed.

matrim

I'll take a look some time this week

is it working for people and just showing errors in the logs?

the merchant

FWIW I'm running the latest version of hassio and it works fine.

kenmc

It's straightforward to do this in openhab at least. I've a script which gets the next 2 buses at a certain stop, and as of this morning it's still running fine. Openhab use java**** to do the dirty parsing work though, so my code is not as clean as I'd like.

The API is https://data.dublinked.ie/cgi-bin/rtpi/realtimebusinformation?stopid=3024

Stop you need to find on the bus stop or website

Hey,

Sorry for bringing up an old thread, but this may have been broken in recent updates.

I assume its in relation to recent changes here in naming scheme. Haven't changed my HA in months, only updating the HA package so I guess this is it.

Will this work for luas also? Any good resources on how you made this also. Been a hobby I've wanted to learn at some point.

I've created one for irishrail. Still beta and not published to the official release, yet

https://github.com/Ordep/home-assistant/blob/dev/homeassistant/components/sensor/irishrail_transport.py

You can set by station and direction/destination

Let me know what you think.

PS: the idea came from the Dublin bus one

Just got a response from dublinked and they have fixed their cert. Doing a wget now works and I assume the plugin is working again. Although haven't had a chance to test yet.

Thanks Matrim. Just checked from a remote connection and all is working fine now. Thanks for that. Now to get some automations setup

Great stuff on the sensor. Have been getting errors the last while tho. Probably better to post on homeassistant forum but maybe you can diagnose quickly? Pretty big error log but bit relevant to Dublin bus....

The site that is used to get the information updated their certificate but haven't configured it correctly. I contacted them over the weekend with details on what is wrong and they said they will look into it.

Fair play on the effort. It should be useful for people near routes. I assume it talks to some real time location monitoring that DB expose. Wasn't aware they were doing that.

It's a fairly simple JSON api and I get the information from https://data.dublinked.ie/dataset/real-time-passenger-information-rtpi-for-dublin-bus-bus-eireann-luas-and-irish-rail
