DIfference between old and new blinds

PederHatlen opened this issue · 1 comments

I have a set of old blinds from ~2009, and some new ones from 2018.
The old ones work great with the system, but the new ones doesn't.
After lending a HackRF for testing I found out that the new ones operate at about 434.48 mhz instead of the normal ~433.4 mhz. It also looks like they use some other type of protocol (not much experience in the field of radio, but it looks different).
I haven't seen any other issues about this but I'll include some pictures of the controllers and readings.

The readings from the HackRF:
SomfyNewVSOld

The new controllers:
NewSomfyRemotes

Old controller:
OldSomfyRemote

Your new blinds use a different protocol: Io homecontrol

It's objectively a much better one...but Pi-Somfy can't talk with them.
