I am pretty sure the current hcalory version does not work with HA versions higher than 2025.7.3. The integration needs some action from Evan...

same here same error, i hope they help to update

yeah in the system log the error points to a bleak file version mismatch. Hopefully Evan can update the files or post a fix. I walked through trying a few changes to force it to use the current version, by removing the == in the manifest.json file, but it kept throwing errors. I don't know enough about the ble stuff or custom integrations at all.

Unable to install package hcalory-control>=0.1.6: × No solution found when resolving dependencies: ╰─▶ Because hcalory-control==0.1.6 depends on bleak<1.0.0 and bleak==1.0.1, we can conclude that hcalory-control==0.1.6 cannot be used. And because only hcalory-control<=0.1.6 is available and you require hcalory-control>=0.1.6, we can conclude that your requirements are unsatisfiable.
