I just recreated the group in Mi Home. It has a different interface now, and the integration is displayed differently. It works now.
Upper entity is older

@rayout yes, it works, but finally I gave up on the idea of creating groups cos automations sometimes didn't work with such entity, for example, when I pressed the switch again immediately after turning on the lamps, sometimes there was no reaction
