Support for KlikAnKlikUt (KaKu) RF433 Switches

bluesheep commented 5 years ago

The KaKu range of switches uses a different RF433 protocol from the RemoteSwitch library.

There is a library to support this at https://bitbucket.org/fuzzillogic/433mhzforarduino/wiki/Home

FYI, technically already supported through raw remote codes.

bjw-s commented 5 years ago

I've been trying to get this working by using the raw codes, but haven't had any luck yet so far 🙁

After looking at the logs with a remote_receiver component, I have managed to see the codes that are being sent by the original KaKu button. Then, in order to send (e.g.) a group on request I have tried to do the following based on the logic as it is implemented in NewRemoteTransmitter:

# Set up remote transmitter

Unfortunately, that doesn't trigger any of the KaKu devices that are listening for that code. When I run a simple Arduino project with the RemoteSwitch library, it does work.

Is there anything else I could/should try?

bluesheep commented 5 years ago

I'm in the same position, I'm sorry for not responding to the previous message. I have been unable to get the raw transmissions to work.

glmnet commented 5 years ago

That is one large code for a single switch.

Are you sure you’re not trying to do several switches?

bjw-s commented 5 years ago

I agree it seems rather big, but that’s what remote_receiver caught when pushing the original button. The ‘new’ KaKu protocol being weird as it is, I thought it could be worth the try.

andrasbiro commented 4 years ago

I looked into this, and I'm fairly sure it won't be possible to support kaku with the rc_switch protocol. Instead, it would be nice to see something similar to Portisch's flexible implementation: https://github.com/Portisch/RF-Bridge-EFM8BB1/wiki/Define-new-protocol-in-RF_Protocols.h (written for the EFM8 on the sonoff gateway, also would be nice to have support for it)

This seems to be a superset of rc_switch - I'm thinking of porting it myself but I don't think I will have the time and motivation to finish it :)

For the record: I've tested the above firmware with Tasmota, and receive is not super reliable - though I suspect it's just a tolerance problem.

andrasbiro commented 4 years ago

Okay, I realized that it is possible to make it work, see above. The remaining issues to fully support kaku:

documentation recommends 250us filter, that's way too high for 433 protocols, kaku can go down to ~150us. I'm using 50us, which converts to 20kbps chiprate - that is unusual, but 10kbps is not.
tx requires sync to be sent at the beginning, not the end. I have no clue how the current implementation works, unless with repeating tx without wait time. If you detect the sync first, you should send the sync first. This come up earlier: https://github.com/esphome/issues/issues/120
kaku requires a footer at the end of the frame. It could be actually received and transmitted as a 1 bit (rcswitch bit, not kaku bit), but that would be the 65th bit of the frame. Instead, it would be nice to have a configurable footer, similar to the sync. As a hack, I tried sending a sync at the beginning and the end, and this did work.

github-k8n commented 1 year ago

It seems the merged PR only enabled support for NEXA protocol, while KaKu is still unsupported. There's more information on the KaKu protocol here: https://manual.pilight.org/protocols/433.92/switch/kaku.html

(On a side-note, the KaKu devices are sometimes received/identified as NEXA devices and sending works if you send the same NEXA code AND repeat it (doesn't work without repeating) which confirms the issue described by @andrasbiro regarding the sync (beginning vs end).

github-k8n commented 1 year ago

Keep in mind that there is "old" KaKu (which gets identified by and works with rc_switch_raw) and "new" KaKu protocol which seems to be related to NEXA. Just as a heads up in case there is some confusion regarding those two.

Old (not related to this issue): https://manual.pilight.org/protocols/433.92/switch/kaku_old.html

New (the topic here): https://manual.pilight.org/protocols/433.92/switch/kaku.html

github-k8n commented 1 year ago

I have three Intertechno ITLR-3500 switches and I could send one of them if it helps to progress here. (also I'd be happy to test new versions of the remote receiver/transmitter components anytime.. using a modded Sonoff RF bridge but also have an ESP32 with a RXB6 receiver)
