Unofficial connector, not affiliated with TomTom. For each trip you enter, Gladys gets the travel time with live traffic, the traffic delay, the distance and the travel time without traffic, read through the official TomTom Routing API (Calculate Route) with a free key.
This integration has never been tested with a real TomTom key: it follows TomTom's official documentation and its tests simulate the answers of the API. Feedback is welcome.
It replaces the idea of a Waze integration: the Waze API can only be reached by getting around its anti-bot protection. A Mapbox Traffic integration by qleg already exists and does the same with Mapbox (forum thread 11024: https://community.gladysassistant.com/t/11024): pick the one whose provider suits you.
The ergonomics (a trip with a name, an origin and a destination, read periodically) are inspired by Home Assistant's "Waze Travel Time" integration (Apache-2.0). No code is taken from it.
Create the free key
- Create an account on https://my.tomtom.com/ (no credit card asked) and confirm the e-mail address.
- Open https://my.tomtom.com/keys: a key named My first API key comes with the account and gives access to the APIs, Routing included.
- Copy it (or create a new one with access to the Routing API).
- Paste it in the TomTom API key field of the integration.
The free plan allows 2,500 requests a day, shared by every use of the same key: if you use it elsewhere too (a website, another application), those requests count as well, and the integration cannot see them. Prefer a dedicated key. If your account moved to the paid "Pay As You Grow" plan, requests beyond the 2,500 free ones may be billed: the integration stops by itself at 2,500 a day, the other uses of the key do not.
The key is kept by Gladys in
its database, never shown again, and sent only to api.tomtom.com. It never
appears in the logs, the messages or the statuses.
Enter the trips
Trips field: one trip per entry, separated by ;. Each trip is a name, the
origin and the destination as latitude,longitude (decimal point), separated
by |:
Work | 48.85661,2.35222 | 48.89198,2.23881; School | 48.80000,2.30000 | 48.81000,2.31000
- To find coordinates: right-click a point in Google Maps or OpenStreetMap, then copy the two numbers.
- Twenty trips at most; two trips cannot share a name.
- An invalid trip is ignored and named in the status, never with its
coordinates: the numbers of the name are masked, and an entry without a
usable name shows up by its position (
#2). A name needs at least one Latin letter or digit, and must not be coordinates itself. - The name identifies the device: renaming a trip creates a new device (the old one keeps its history). Changing its coordinates keeps the device.
- Addresses are not supported yet (no call to TomTom's Search API): give coordinates.
Options shared by every trip:
- Vehicle: car, or truck (the roads and speeds of a truck, without its dimensions or weight).
- Avoid toll roads, Avoid motorways.
- The departure is always now, with live traffic.
The devices
Once saved, each trip shows up in the Discovery tab. Add it to get:
| Feature | Gladys category | Unit |
|---|---|---|
| Travel time with traffic | duration | minutes |
| Traffic delay | duration | minutes |
| Distance | distance-sensor | km |
| Travel time without traffic | duration | minutes |
Values are rounded to a tenth. The travel time without traffic is the one
TomTom computes without any traffic (noTrafficTravelTimeInSeconds).
The quota and the interval
Each read of a trip costs one request. Requests a day = trips × (minutes of the reading window ÷ interval).
| Interval | Requests per trip and day (all day long) | Trips that fit |
|---|---|---|
| 5 min (minimum) | 288 | 8 |
| 10 min (default) | 144 | 17 |
| 15 min | 96 | 20 |
- The status of the integration shows the planned requests a day after each save.
- A configuration planning more than 2,500 requests a day is refused: nothing is read, and the status says what to change.
- The integration counts its own requests per UTC day and never sends more
than 2,500, scene refreshes and test button included. The count survives a
restart (a file under
/data). - Manual reads (scenes and test button) have their own cap per UTC day: 100, and never more than what the planned reads leave of the 2,500 (e.g. 2,500 − 2,448 = 52). Beyond it, the scene action gives back the last values without a request. A configuration planning exactly 2,500 requests leaves no manual read: the scene action and the test button then only give back the last values.
- The periodic reads never read a trip faster than its interval, even after an error, a reconnection or a restart; a manual read at most every 2 minutes per trip.
- When the
/datafolder cannot be written, the status says so and the first reads wait one whole interval after each start. - A 429 from TomTom pauses every request (Retry-After, else 1 minute, doubling, between 1 minute and 6 hours). A 403 for the daily quota pauses them until the next UTC midnight (1 hour at least). A refused key stops the reads, with one new try every 6 hours until the key changes. These pauses survive a restart.
Reading window (optional)
To save the quota, read the trips only between two hours, e.g. 6 to 20 (14
hours: 84 requests per trip at 10 minutes). 0 to 24 reads all day long; a
window may cross midnight (22 to 6). The hours are those of the given time
zone (the one of your Gladys, Europe/Paris by default). Outside the
window, the last values stay shown and are not sent again.
Scene: refresh a trip now
The scene action Refresh a TomTom trip now reads the chosen trip at once,
unless it was read less than 2 minutes ago, or the manual reads of the day
are spent (see above): it then gives back its last values without a request.
Simultaneous calls send one request only. A scene in a loop therefore uses at
most the manual reads of the day, never the periodic ones. It works outside
the reading window too. Outputs, for the following actions: refreshed
(read now or not), age_minutes (age of the values), travel_time_minutes,
traffic_delay_minutes, distance_km, no_traffic_time_minutes. The next
periodic read comes a whole interval later.
Example: every weekday at 7:30, refresh "Work", then send a message when
traffic_delay_minutes is over 10.
"Test TomTom" button
Reads the first trip (one manual read, at most once every 2 minutes), then shows the planned requests, the ones used today (manual reads included), and the last values of every trip.
Privacy
The coordinates of your trips (often your home) and the key are sent to
TomTom (api.tomtom.com) on each read, and to nobody else. The file
/data/tomtom-state.json keeps the count of the day, the pauses, a hash of
the key (never the key) and the instant each trip was last read.
Troubleshooting
- "TomTom refused the API key": check the key on https://my.tomtom.com/keys and that it has access to the Routing API. A 403 TomTom does not explain (a proxy, a CDN) is not taken for a refusal: a pause that doubles each time.
- "no route between the points": a point is far from any road, or the points are not linked by road; tried again every hour at most.
- Configuration refused: raise the interval, shorten the reading window or remove trips.
- Integration logs: from the Gladys interface.
