Lightwave Relay LW821 - Stop Command

[steve-b]

I use a Lightwave Relay LW821 to control my curtains along with an RFXCOM RFXtrx433. The LW821 relay has two switched contacts with a common connection, so on is switched 1 and off is switched 2. These connection can be no volts or mains live depending how you wire the relay. There is also a stop command that can be sent to the relay which corresponds to no connection to either switch position.

Unfortunately my curtain track has broken and I need to replace it. Most of the new curtain tracks available require a momentary contact to open and close; the stop (no-contact) would be ideal for this.

My question is possible to use Domoticz to send the lightwave stop command to the relay? (Using scrips maybe.) The only options available are on and off.

I read that the lightwave Stop command is given in the RFXCOM SDK but I dont have access to this so do not know what the commands are.

Thanks

Steve

Even a simple yes/no would have been useful.
