kaku/learning problem

[rickb100]

@robertklep: thanks for the plugin.
i got the klikaanklikuit plugin installed in homebridge. when i switch a lightbulb in apple home i can measure a voltage pulse (~1V) on the selected pin of the raspberry zero using a multi-meter. so that probably works. Although when I set a device (ACD-200) in learning mode and send an on signal nothing happens.
i tried to install the kaku-rpi to learn the codes as you suggested in other issues although i cannot get that tool installed, see errors below. Do you have any suggestions on this issue?
Thanks.

Try with this:

$  sudo npm i kaku-rpi -g --unsafe-perm

Thanks that worked, I was able to install the kaku-rpi!

Although switching/learning the ACD-200 units still did not work. I use a raspberry zero. If I select pin 37 (GPIO 26) and execute for example:

kaku 37 5224 0 1
then i can measure a signal on pin 37 with the multi-meter although the ACD-200 does not switch/learn. I have reset the ACD device before starting.

Any GPIO pin should work right?

I think I will replace the transmitter to check if that solves the issue

[robertklep]

Instead of a numerical address, try using one of A, B, C, D, for instance:

kaku 37 A 0 1

I don't know the ACD-200, perhaps it's an old-style device (or it accepts old-style addresses).

thanks for the help. I tried several things and it did not work on the raspberry pi zero. Then switched to a raspberry pi 3 and everything works perfectly.

[robertklep]

@rickb100 thanks for the update! I don't know why it doesn't work on the Pi Zero (although I've never tried myself so not sure if it's supposed to work on it at all).

[rickb100]

I'm not sure, read online that more people had issues with the pi zero and the rf transmitter.
