Ok, can you try escaping the backslash as its JSON. i.e put double
\\x02POF\\x03\\0D
. Also have you verified that the baud rate and the other settings are correct for your connected device?

Double backslash also doesn’t work I’m afraid.
Setting on the WF2SL are correct as far as I can tell

I was referring the config in the apps JSON, my understanding is that overrides the stuff configured on the iTach.
However I found one issue with the config cmd sent and also put in some debug logging. Can you have another go after updating the app?
EDIT: one more fix pushed

Oh , you meant these settings?
Seems like they are ok as well.
I also tried renaming “PARITY\_NO” to “PARITY\_NONE” because that’s what the setting is called on the WF2SL but that didn’t help.
Just installed the latest version but it’s still not working.
What I did notice looking through your code is that in device.js in master/drivers/ip2sl/device.js it says “class ITach **IP2IR** Device extends ITachDevice” while the IP2CC has “class ITach **IP2CC** Device extends ITachDevice”.
Should it say “class ITach **IP2SL** Device extends ITachDevice”?
Mind you, I have no coding experience what so ever so please excuse me if I’m talking bullsh\*t 😉

Oh, you’re totally right, i’ve pushed another fix… not sure if that was a problem though but perhaps, it depends how homey loads the classes as it was under the correct driver directory. Did you get any new output log?

Now it crashes right after I run the flow.

ok I possible found a problem , can you try the new version.
Also on your second command I think the last char should be \\x0D
I think the only format thats supported now is the second command in your example (on2), if you need those control characters.

Ok, just to double check , the only command in logs above that I think is supported right now has power off (POF)
instead of power on PON
sending payload \x02POF\x03\x0D
Is this correct?

Yeah I noticed it send POF instead of PON just after posting but changing it to PON didn’t make a difference.
I kept forgetting to change the text-file I copy from but just changed it so it won’t happen again 😉
Every test I tried 3 codes and after your suggestion now 4 codes:
PON
\x02PON\x03\x0D
\x02PON\x03\0D
|02|PON|03|0D
None work unfortunately.

Ok, its very strange that it doesn’t work. I have even set up iTest now and debugged what that one is sending against a mock server (simulating the iTach) and its exactly same as from the app from what I can see. Can you post a screenshot on a working iTest example with a working command. Its running on port 4999 (Serial 1), right?

This is what works using iTest.
Indeed port4999 (serial 1).
In the screenshot the literal button is highlighted but I use mixed button to send the command

Can you try with this format instead:
\u0002PON\u0003\u000D
Use _single backslashes_
Special codes (hex) needs to be \u and 4 digits, so just prefix them with 00 as its coming from JSON, my fault, should have thought about that earlier 🙂

YES!!! It works!
Power on, power off, lensmemories, 3d settings 🎉
Man, I’m am so happy 😋
Thank you so much for your efforts and help!!
