Need something to "buzz in" guests?

I have a classic, simple buzz in switch in order to let the visitors in. Is there any device that I could plug in between gate and buzzer in order to be able to do it via Homey?

Maybe this one?

something other than z-wave? no range, since I dont have a z-wave mesh

Shelly 1 has a dry contact, seems like it should be able to do the job.

not sure about power then, but will try. thx
