Which manufacturers have impulse relays with separate control inputs for switching on and off?

I want to use impulse relays in the "smart house", so that the switches (buttons) throughout the house work as usual, and the control piece of iron can turn certain groups on or off with guarantee (without the need to know what state the relay is in now). It seems that relays from Meander RIO-1 are excellent for this purpose , on which 3 buttons can be hung: switching (on-off-on-...), on, and off:

Are there relays with such functionality from other manufacturers?

It looks like I was in a hurry with the question, because either the relays themselves, or the ability to dial this functionality from the modules, most manufacturers have and is called "centralized control"
For example, Schneider Electric A9C33111 is exactly like that.
And here is the scheme for its implementation:

And other manufacturers have additional modules that implement this functionality in addition to the impulse relay, for example:

  • ABB E290 + E293 (you will get the same circuit as above: with the same control voltage on all inputs)
  • ABB E290 + E294 (the additional module may have a control coil for a different voltage than the main module)
  • Hager EPN510 + EPN050

And they fit together like this:
