Two covers acting as one cover

[MarvinE (Marvin)]

Hi all,

I have two Shelly 2.5 devices controlling two roller shutters, but I only want to connect one real switch to the devices. So 1 Shelly is connected to a switch (for manual control) and one is not. Combining the covers in home assistant is easy enough, but combining them for the manual control seems a bit difficult. Does anyone have an idea how I can have the second roller shutter “mirror” the motion of the first roller shutter, when it is controlled manually?

I use this to sync the status of multiple entities so that you can control just one and the other will mirror. Works great for me.

Link On/Off State of Multiple Devices

Link On/Off State of Multiple Devices v1.0.0 [Open your Home Assistant instance and show the blueprint import dialog with a specific blueprint pre-filled.] View source code Select multiple entities to link their on/off state. If any selected entity is turned on or off, the other selected entities will be sent a matching on or off command. You can select any entity, but only entities supported by the homeassistant.turn_on or homeassistant.turn_off service calls will work. Requirements All …

It Is designed for on/off states, I don’t know if it can work for covers. Probably can bè adapted for the use.
