Shelly 2PM Gen3 to control a 230 V AC linear rack actuator?

Hello

I have a skylight that can be opened by using a remote to control the motor. I can't control the motor by using a switch on the wall, but only by using a remote. Unfortunately that one broke down. Instead of buying a compatible (and expensive) new remote, I would like to use a Shelly to control the motor. That also opens new possibilities like opening the skylight when it is to hot.

The label of the motor says Ultraflex Control Systems - Rack 230 V AC - PN: 40211T - 230 Vac 50 Hz 23W IP 55. A Google search gave me https://ultraflexcontrolsystems.it/prodotto/rack-…on=rack-230-vac, where I found a Downloads-tab. The user manual gave me the electric connection below.

Could I control this 230VAC motor with a Shelly 2PM Gen 3? And if so, would the wiring beneath be a correct one?

Would it make a difference if the motor wasn't a 'Rack 230VAC', but the version 'Rack 24VDC'?

Q1: My electrical ceiling window is connected to a 2PM. I was using this schematic and it works fine.
For an alternate control, I use a push button switch as well. However, sometimes the smartphone is not available.

Q2: You have to observe the polarity of 24VDC.

An addendum to Q2: The 24V DC version does need a commutator relay (or a modified Shelly 2PM Gen 3):

For details check the forum for terms like „Polwender“ or „Hühnerklappe“ or „TV-Lift“ or „Linearantrieb“. For modified Shelly 2PM Gen3 have a look at this thread:

RE: Modifizierter Shelly 2.5 mit Polwende-Funktion (auch mit plus 2PM und 2PM Gen3)

Mit einem Shelly 2PM Gen3 ist der Umbau zum Polwender sehr viel einfacher zu lösen:

Der Shelly 2PM Gen3 hat kein separates Sub-Modul für die beiden Relais, sondern nur eine Basis-Leiterplatte. Mit zwei zusätzlichen Bohrungen

lassen sich die originalen Relais gegen den Typ…

Indeed, the smartphone isn't always available :-(, so I might add a push button switch in the future. There is no cabling from the ceiling to the wall, so I might use a Shelly BLU Button. But first I'll try to have the basics with a Shelly 2PM Gen3 working :-).

Thanks for the elaborate information about the 24V DC! Luckily I have the 230V AC version, but I might delve into the details thgoebel provided.

Basically the Shelly 2PM Gen3 (or Gen4) should be the right device, but I am not shure what the MINIMUM motor power requirement is for a successful cover calibration.
This motor only uses 0.1A@230V "under full load" which is quiet low. Perhaps someone has more information about a minimum power requirement?
