What is wrong with this immediate script line

[masman]

&hs.ExecX10 "A2", "no cmd", 0, 0

[jon00]

hs.ExecX10 as a command does not exist in HS3.

Thanks. I guess I need to give up my old x1`0 devices that need to be sent addresses.

There is an "equivalent" in HS3, but it's a bit less convenient to use. See this:

This might do what you want.

    Public Sub Main(ByVal Parms As Object)

        Dim X10plugin As HomeSeerAPI.PluginAccess = New HomeSeerAPI.PluginAccess(hs, "X10", "")
        Dim strRet As String

        strRet = X10plugin.PluginFunction("ExecX10", {"A2", "no cmd", 0, 0, False})

    End Sub
