If your MM is using the default Weather module with the EnvCanada provider or the 3rd-party MMM-EnvCanada module, there are some upcoming changes announced by Environment Canada that might impact your MM config in some very specific cases.

Change #1: A handful of siteCode values are changing and will require a minor config.js update. The changes are:

Change#2: A handful of siteCode locations are being relocated to new locations within 5km of the original. This is unlikely to require config.js updates but the changes have been highlighted as FYI. They are:

These Env Canada changes will come into effect as of Oct 6, 2026 are being done to align with other Canadian government databases. I suspect they will impact a very small number of module users (if any).

Nice job! I wrote the default module code but always wanted to see a dedicated module with a better UI. I like what you’ve done!

Just a further update… Environment Canada actually got back to me and confirmed that they did have a problem with load balance caching and this has now been resolved. I confirmed with my own MM that the correct data is being returned to the weather module’s envCanada provider.

Hello! My name is Kevin and I am from London, Ontario, Canada. I’m 58 years old and recently retired after 37 years in the IT profession - started as a software developer and then somehow morphed into a Senior Architect designing various things such contact centres and voice applications. I also very occasionally teach IT courses at our local college. I’ve been married for over 30 years and have 2 grown children.

I enjoy tinkering (without always knowing what I’m doing), hiking, traveling, and playing hockey because Canada :)

My COVID project has been to build a ‘family info screen’ using the MM framework. It is hanging in my kitchen and currently doing things such display family photos from a local NAS, show local weather, show local waste collection calendar, etc. all with voice support. I will say that if not for the patience of this community, I would not have been successful with this build! My current project is to create a new provider for the default weather module to pull data from Environment Canada - seen running here on my MM build:

I look forward to adding more functionality to my display in the future!
