Met Eireann weather integration using deprecated URL, which is now broken

[gdude2002]

The problem

As of this afternoon, the Met Eireann integration fails to pull any data. This is because the URL it's polling times out: http://metwdb-openaccess.ichec.ie/metno-wdb2ts/locationforecast?lat=<SNIP>;long=<SNIP>;alt=<SNIP>;from=2024-11-21T19:00

According to the Irish Government website:

Announcement: The upgrade of the api will result in termination of the old 'metwdb-openaccess.ichec.ie' URL by 15th September. This is replaced with 'openaccess.pf.api.met.ie'.

URLs of the form:
http://metwdb-openaccess.ichec.ie/metno-wdb2ts/locationforecast
should be replaced with
http://openaccess.pf.api.met.ie/metno-wdb2ts/locationforecast

Disclaimer This API services and data offering is scheduled for upgrade starting Q1 2024. Every effort will be made to maintain data access during the upgrade period, and services/data will be provided on a best effort basis.

Seems we may be a little behind with this one! Any chance of a quick fix?

Thanks!

A hack that got the integration running again for me is to override the DNS entry for the old site metwdb-openaccess.ichec.ie with the IP address of openaccess.pf.api.met.ie (== CNAME az.openaccess.pf.api.met.ie == 137.116.252.12)

There are a few ways to do this. I have added this DNS override to my internet router, how to do that is completely router dependent. If your HA instance resolves DNS through pi-hole, then you might be able to add the override in Local DNS > DNS Records. It might also be possible to add an override (ie. 137.116.252.12 openaccess.pf.api.met.ie) in /etc/hosts within the homeassistant container, though I have not tried this, and this change may be overwritten on each HA restart.

Note that this hack depends on the web server of the new site not looking at the site name in the request URL. If they fix this to serve only requests to openaccess.pf.api.met.ie, then this hack will stop working.

You haven't noticed any loss of functionality with this approach? If that's the case, maybe we should just PR the change, I imagine it's a one-liner

[crowbarz]

It got my temperature and humidity back :) I have not tested this extensively in the ~20 mins since I made the change.

The PR for the URL change will need to be submitted against https://github.com/DylanGore/PyMetEireann . However, note that the owner has not submitted anything to GitHub since 8-Aug-2023, over a year ago. Only after that package has been updated and re-released can the HA integration be updated to pull the new version of the package.

I noticed that as well, but the author has been active on LinkedIn, so I remain hopeful! Maybe it'd be worth bugging them there? It does seem like that repo is basically unmaintained.

PR DylanGore/PyMetEireann#8 submitted

[gdude2002]

I've been trying to figure out a way to contact the guy - it looks like he's made himself quite difficult to contact, unfortunately.

• Dev.to - seems abandoned
• LinkedIn - wants me to pay an eye-watering 120 euro/month to send messages to people I don't know
• Twitter - private account

His website does contain an email address, which I'll try contacting shortly and get back to you.

@crowbarz @gdude2002

Will this fix to the DylanGore/PyMetEireann repo be merged automatically into Home Assistant or is a pull request needed?

Thanks for flagging and helping fix the issue.
