Send "STOP" command via Somfy ZRTSI - Z-Wave to RTS Interface

[raypp2]

I'm looking for a command that could trigger the STOP signal in Somfy window shade motors. It seems this should be possible by sending the following:

0x26 COMMAND_CLASS_SWITCH_MULTILEVEL argument: 0x05 (SWITCH_MULTILEVEL_STOP_LEVEL_CHANGE)

I've tried a number of unsuccessful variations on: zwave.setValue(shade_node,38,1,00x05);

My UP and DOWN commands have been working correctly.

Reports of Working Z-Wave Commands

In the UI, if a device supports COMMAND_CLASS_SWITCH_MULTILEVEL, the UP button sends SWITCH_MULTILEVEL_START_LEVEL_CHANGE with the arguments 0x60, 0x0, and the DOWN button uses arguments 0x20, 0x0, while STOP does SWITCH_MULTILEVEL_STOP_LEVEL_CHANGE.

If the device does not support that command class, but does support COMMAND_CLASS_BASIC_WINDOW_COVERING, the UP button sends BASIC_WINDOW_COVERING_START_LEVEL_CHANGE with the argument 0x0, DOWN sends 64, and STOP sends BASIC_WINDOW_COVERING_STOP_LEVEL_CHANGE.

"i tried using a z-wave send raw command using bytes "0x26, 0x05" as above. i can confirm that it works as STOP, i.e. when the shades were moving and this command was sent, the motors stop in their current position. "

The stop command serves a number of important functions:

1. Stopping the shade while in motion
2. Sending the shade to a programmed position when triggered in standby (i.e. 50% down)
3. Programming key settings like upper limit, lower limit, device pairing, etc ...

What ValueID's do you have exposed on this device?

If you have the Increment/Decrement ValueID's, the Stop Command is sent when the Button is Released.

any update?

I had the same problem, but eventually got it to work. Here's how to use the Somfy ZRTSI interface:

To make the shades go down, "push" the Bright button: zwave.setValue(<shade id>, 38, 1, 1, true);

To stop the shades while they're moving down, "release" the Bright button: zwave.setValue(<shade id>, 38, 1, 1, false);

To make the shades go up, "push" the Dim button: zwave.setValue(<shade id>, 38, 1, 2, true);

To stop the shades while they're going up, "release" the Dim button: zwave.setValue(<shade id>, 38, 1, 2, false);

Hi @joelrbrandt, what API are you running in your examples? I wonder what the arguments represent (besides the shade id of course).

I am trying to do the same - make the dimmable part work with my roller shades so that the shade stops at 25, 50 , 75% and I am wondering if all it takes is adjustment of the values that homseer uses to send to the shade?

Much appreciated. Tomasz

My setup:

• Z-Wave to RTS interface: 1811265
• Roller shades controlled by Sonesse 30 RTS motors
• HomeSeer HS3 Standard Edition 3.0.0.548 (Linux)

Never mind, just realized what page I am on :) .... open-zwave of course After searching the API here: http://www.openzwave.com/dev/namespaceOpenZWave.html it is not obvious to me what class the zwave object is of, in the above example. I guess I will pull the code down.

I wonder if I will be able to translate these params to homseer params.
