Regarding Matter, I do have the updates for NO2 and the fan, thank you! 
However, I see ‹ Add to Gladys › even though the services already exist and have the exact same name.
When I click on Add, it updates device 28 with the NO2 (and therefore not a new service) but I can’t do the same for 27, nothing happens.
Hi,
I’m having the same issue as @mutmut with my Dyson, can’t update it.
I’ve also noticed another issue with my water tank level sensor, it’s switched to meters:
Thanks @pierre-gilles for your reply.
Regarding the Matter device, there is no update button, only an add button.
And when I click on add, nothing happens and nothing in the logs
Ok, I think I’ll add a bit more information about the interface to better understand the issue here 
In the meantime, I’ve created a ticket to keep track of the bug:
@mutmut @Nagromdark Ok, I’ve modified the frontend to display the error more explicitly. This change will be included in the next version of Gladys Assistant
In the meantime, as this is a purely frontend change, we can already test it via a Gladys Plus test URL (available immediately) here: https://display-matter-save-error-in.gladys-plus.pages.dev
Can you test and give me the error?
@pierre-gilles logs sent in DM
EDIT: I didn’t realize, but when I « add to Gladys », I thought it was an update because it was exactly the same name and especially after that I had only 1 device.
But when I looked at my dashboard where I had put the air info in a device, well everything related to Dyson air disappeared 
Hi @mutmut,
Thanks for testing. Good, but the screenshot doesn’t help me much, so I’ve added more information to the interface to get more data!
Can you re-test on: https://display-matter-save-error-in.gladys-plus.pages.dev/ ?
No need to send me the server logs, the error message is purely frontend!
Thanks
