Most of hardware using 433MHz don’t notify the emitter if the action requested has been well realized.
If you have multiple devices using 433MHz then the collision risk will be higher.
I am using pimatic for my thermostat, it usually works very well (there is a simple 433MHz switch controlling my boiler).
But sometimes the message send to the switch of the boiler will be lost and in that case the boiler will stay on or off…
The homeduino seems to be able to repeat RF messages:
homeduino.coffee: Repeats: #{config.rfrepeats}"
Is it possible to introduce a delay between messages something like 1 or 5 seconds between each repetition?
Like this you can send 10 times the same order and maximize your chances to get it from the switch…
