Thank you, Sergiy! Finally, it worked.
Just out of curiosity, why would the "Generate Response" option not work, since that's already on that page?
Istvan, I have been trying to create a REST service to update the channels but have not succeeded. Is it possible for you to post the instructions on how you set it up? Thanks.
I have tried numerous times to get an API Express implementation of sending channel information back to Appery for a device. The response shows the correct channel values, and returns a 200 OK status, but checking the Devices DB does not reflect the channel request.
I'm still having issues with this. Please see my code in the reply below, and hopefully, you might have some advice.
