This is a SmartApp to connect to a TaHoma® by Somfy system.
It can only control roller shutters because I don’t have other TaHoma® devices to test with.
Note this isn’t using the ZRTS Z-Wave link but the TaHoma® box and requires a tahomalink.com account.
It is a limitation of the RTS roller shutters that position is not reported therefore the position in SmartApp will not be in sync with actual roller shutter position if shutter is operated from remote control.
