haven’t tried the upgrade yet but I was afraid that the newly dictated thermostat card would break things.
I especially use card mod to change the colours of the text and slider to show heating which especially important when using passive mode. I also suspect that the new card doesn’t show this correctly - can anybody can confirm?
I’m very new here so excuse any newbie misunderstanding. I’m loving the integration. I just updated to 2023.12 and it broke. Same errors as you, so have rolled back to 11.
So HA2023.12 did update aiohttp again and caused this integration to fail for some. It seems the hubs randomly (frequency varies) sends extra data at the end of the response which the latest 3.9 version of aiohttp raises and error for.
As such, I have updated the api to no longer use aiohttp but httpx and this seems to resolve. I have released v3.4.0 with the fix for this that should now work on 2023.12.
Few notes:
Due to urgency, I have not had time to thoroughly test, so please let me know if you see any wierd behaviours/ errors in logs.
@LGO44 - I have not had chance to update the v2hub support with some of the feedback or your PRs but this v3.4 does include PowerTags and tilt functions for shutters (without your corrections). I will try and look at this in the coming days.
@msp1974 updated to v3.4.0 beta, and still on HA 2023.11, but I seem to have a duplicate set of devices for my bedrooom, only this room, other seem fine, how can I remove the old duplicate, as it says entities are no longer available.
Is anyone else having the issue of when you press a mode button on the new thermostat card it jumps up to the top of the page, or does anyone know how to stop that.
New to HA and have a Drayton Wiser Hub, 2 thermostats and 2 itrvs. Now I managed to get it all setup on HA. I’ve also seen on the forum that trvs can be added directly to HA. My questions is can I pair a completely different model trv to HA and get it to interact with the Wiser integration to control the remaining radiators or do I need to stick with the wiser trvs?
Just catching up on recent developments. I too, was worried about the new cards breaking everything when they inevitably appeared in the dashboards and not just the dialogs. I mentioned it a while ago. I have specifically skipped this version, as I am expecting a lot of rework will be needed as I too am using card-mod to modify the colours for Passive Mode and I don’t really like the way the new cards deal with upper and lower temperatures compared to the original ones, with the uncoloured gap in the middle, and with the target temperature now being larger than the current temperature. Visually the original style was much clearer IMO. I think there is going to be a lot of faffing with card-mod trying to recreate something similar to the original.
You have to laugh or you’d cry. It seems to happen almost monthly now. Stupid UI changes that have not been properly considered. There’s a small outcry about the new thermostat card design in the 2023.12 release discussion thread, more about the switching of the target temperature and current temperature sizes than anything else.
@Duke_box Thank you for nicely reflecting my views on this over there also. I do get a bit fed up with the mods reacting with a small degree of hostility and shooting down totally valid criticisms as if we’re all stupid, so I try to refrain from commenting in the release threads (unless I know the answer to something) wherever possible. It’s certainly not as friendly a place as here.
Anyway, unfortunately I doubt we will get the original thermostat card back no matter how much noise we make. So unless someone can fork it and make a custom card to put in HACS, it looks like we are stuck with the new one. @msp1974 If I had the ability to do this I would, but I have no idea where to begin. I don’t suppose this is something you are able to do?
In the meantime, for anyone else that agrees with at least switching the size of the temperatures back round to the way they were, please vote here.
Hopefully there will be a bit of row back on this and/or maybe someone will be able to create a custom card from the original. Until then I won’t be in any rush to upgrade.
I see you had some rogue devices after upgrading the integration to 3.4.0.
@msp1974 Is 3.4.0 OK to run under 2023.11.x for those of us that haven’t and aren’t planning to upgrade to 2023.12.x yet? I’ve held off updating the integration as well, as I wasn’t entirely sure whether it was a release specifically to address the aiohttp issue in 2023.12.0 or whether it’s fully backwards compatible with 2023.11.x as well?
