world tides info custom component for Home Assistant.
This component is used to retrieve tide information for a dedicated location (all over the world) : https://www.worldtides.info/
This component allows to :
- display the tide curve (height)
- give the current height
- give the next tide
- give tide tendancy, amplitude
- display location on default map
- display tide prediction over user defined period
- insert tide extrema in calendar
==> the monitored location is either static, either given by GPS data (tracker)
WorldTidesInfo uses credit. Hereafter example with 1 day prediction :
-
In static, refresh rate (Scan Interval) is every 15minutes with refresh of data from server once a day (3 credits). NB: At init 5 credits.
-
In motion, refresh rate (Scan Interval) is every 15minutes with refresh of data from server once a day (3 credits), or if the position has moved more than a user parameter defined in UI (the new position information are then request : 5 credits)
-
Please refer to https://www.worldtides.info/developer for pricing (as few requests are done per month, prepaid seems to be the best deal).
- As an example, in static, as the request per day per location uses 3 credits : for one location, 20000 credits will last ~18 years
Either use HACS (default), either manual
HACS (Home Assistant Community Store)
- Go to HACS page on your Home Assistant instance
- Select
integration - Press add icon and search for
worldtidesinfocustom - Select worldtidesinfocustom and install
Manual Procedure
- Download the folder worldtidesinfocustom from the latest release (with right click, save link as)
- Place the downloaded directory on your Home Assistant machine in the
config/custom_componentsfolder (when there is nocustom_componentsfolder in the folder where yourconfiguration.yamlfile is, create it and place the directory there) - restart HomeAssistant
detail description
Version V2.5.0: Remove CreditCallUsedForInit attribute as init data are also refresh periodically (1 month)
Version V2.6.1: After this version, the information given is by default with unit system configured in HA (metric or imperial). NB: Before V2.6.0, information were given only in metric. At V2.6.0 the information given is by default in metric.
Version V2.7.0: After this version Coeff attribute is renamed in Coeff_resp_MWS . MWS stands for mean water spring.
Version V3.0.0: After this version worldtides_request_interval configuration optional parameter is removed.

Thanks home-assitant community !
Thanks Home-assistant project !
Since V1.0.0 :
- use of WorldTidesInfo results
- to be used within Home Assistant.
Since V5.0.0 :
- matplotlib is used
Since V8.0.0 :
