Hi, I have recently bought a second hand Master Link Gateway mkII and I'm looking at blind options. Clearly the Lutron Blinds are a known working option, but extensive so I am looking at the Somfy blinds. These blinds have an optional RTS Transmitter that can be feed from a home automation system. Does anyone have any previous experience of interfacing the MLGW with the RTS transmitter with success?

Many thanks
hi corona!
look to the lintronic TT455-RT-238 on http://lintronic.dk. you can control the lintronic box via rs232 with custom strings. maybe lintronik can control the somfy transmitter?
BS Ouverture, BS 9000, AV 9000, Avant 32 DVD, BV9, BV6-22, BS 5, BS 4500, BS 7000, BC 9500, Beo6, BL Penta, F1000, BLGW, etc....
Hi,
I had the same issue with Somfy blinds and controlling them using the Beolink Gateway. I found this online and thought I would give it it try because it was significantly cheaper than the Somfy RTS transmitter.

I worked very well with the enclosed software but I could not get it to work at all with the BLGW, maybe a better person than me may be able to reverse engineer the commands that the software sends the transmitter. As a solution I added the RFX transmitter to a Raspberry Pi and used that as a bridge, so the gateway talks to the Pi and the Pi sends the commands to the Somfy via the RFX transmitter. It works perfectly and cheaper than the Somfy 485 transmitter.
Many thanks, this looks like a potential solution.
Thanks, I will look into this and report back
I have used mlgw and connect to somfy rts transmitter thru rs232 and used customstring so it works
Hi, thanks for this, question if I may (I'm not that technical), how did you wire the RS232 to the TRS transmitter?
Thanks
tompa:Hi, I have used mlgw and connect to somfy rts transmitter thru rs232 and used customstring so it works
I know in the US market they make a RTS RS232 compatible controller, but for some reason in Europe only the RS485 is available.
It's some years ago but for the Cable i remember i solder a simple 1 wire txd mlgw to rxd somfy rts and 1 wire gnd thats it
i see if i had the programming for the customstring on mlgw and get back
I don't notice that problem iwas rs485 on european rts, this was some years ago and i use a US model with rs232 but maybe it's possible to use rs232 -> rs 485 converter maybe? or buy US model because RTS transmitter use 433,92 mhz in US also i not sure now but probebly the same
You only type in for example 0103U in match/command field in mlgw = RTS adress 1 motorchannel 03 (1-16) and motor UP
or 0103S in match/command field in mlgw = RTS adress 1 motorchannel 03 (1-16) and motor stop
or 0103D in match/command field in mlgw = RTS adress 1 motorchannel 03 (1-16) and motor down
all as output command in type field in mlgw
/Tompa
yes rs232
and i wrote wrong in earlier post (433,92Mhz )but somfy use 433,42Mhz but it's the same in US and EU so it would be no problem to use the RTS universal interface II US model in europé (and that was the interface i used)
