Sonoff dual ch R2 vs 4ch pro R2 for roller shutter?
started a topic
over 2 years ago
I have been using sonoff devices for a lot of small projects but since a couple of months i have been using the 2 sonoff 4ch pro for 4 window roller shutters.
I am using 1 sonoff for 2 shutters ( 2 relays for up and 2 for down)
This works but i can only open or close 1 shutter at the time or if i choose inching mode it is max 4 sec which is not enough.
I saw now the 4ch pro R2 with inching mode up to 16sec and the timing/countdown mode so this means with 2 x 4ch pro R2 i could open or close all my 4 shutters at the same time for a closing or opening time up to 16sec which is enough now.
The question is should i invest for roller shutters in 2 new 4 ch pro R2 or should i use 2 dual ch R2 per roller shutter ( 8 in total for 4 windows) a bit much..
But i saw a lot of people online using the dual channel for roller shutters with external buttons for manual up and down.
What is the best type of solutions?
What do you suggest?
