Send 433mhz commands twice

[toreandre]

Since 433mhz does not confirm that a command was executed (and received by the receiver), would it be possible to add a choice either to the specific hardware (in my case a tellstick) or the individual devices to send the command twice?

So when i turn off a light domoticz tells my tellstick to send the same off command twice with a few seconds delay.

Easy with litle scripting.
Not sure if it's a good choice to sent even more data in the small 433Mhz band.
