newbee90 commented 3 years ago

a code is only send if a name is shown, you can't send a unknown signal

serial monitor Signal received: One line: 8D03E0FA:UNKNOWN:21 uint16_t rawData[41] = {922,2282, 466,1614, 480,932, 464,1632, 464,1632, 464,1632, 464,934, 464,934, 464,934, 464,932, 464,1630, 466,932, 464,1632, 466,932, 464,1632, 464,1632, 464,936, 464,1630, 488,910, 488,1608, 486}; // UNKNOWN 8D03E0FA

http://192.168.178.33/msg?code=8D03E0FA:UNKNOWN:21&pass=1234 //is not sending but if I change UNKNOWN by sony http://192.168.178.33/msg?code=8D03E0FA:sony:21&pass=1234 //is sending but TV is not responding so how do I setup tehpsyc.pythonanywhere.com to send my codes

You can't send an unknown code, it means your code isn't reading correctly or isn't supported by the IR library Only possible workaround is to send the RAW version of the code

I changed IrremoteEsp8266 to 2.7.13 am my code is not UNKNOWN anymore, now I can send code with http://192.168.178.33/msg?code=5C2B5:METZ:19:0x3&pass=1234 but if I put in my amzn1.account.AFVDKGxxxxxxxxxxxxxxxx from tehpsyc.pythonanywhere I get Unauthorized, HMAC security authentication and serial monitor says 22:45:53.132 -> Connection received - MSG 22:45:53.132 -> Failed security check, signature is too old 22:45:53.132 -> Server: 0 22:45:53.132 -> Local: 1609019152 22:45:53.132 -> MID:

Signature is too old, is your EPOCH time wrong? The security check is time sensitive so if your system clock is wrong (usually because of a DNS error causing the NTP query to fail) then the security check will fail as well

newbee90 commented 3 years ago

the difference is 2 sec 493938ms uptime; EPOCH 1609056117 / 1609056119 ( 2 )

Are you sending the command from alexa or just from your URL? Once you enable the security stuff you can't send commands over the URL anymore (unless you include all the authentication headers)

newbee90 commented 3 years ago

I send it from URL and get Unauthorized, HMAC security authentication where do I put the authentication headers? if I try by Alexa it says TV does not respond I live in Germany, hope this is not the problem
