Is there a possibility like how blynk button works ,like when i switch on or off immediately hardware updates …like this when i for example a field value changed in my channel from thing speak ,blynk would able to sense the change and get the information… i am not talking about updating values from hardware I just want to get the information from web url…i knew there is a limitation on number of requests.
Using web hook from blynk looks slow just for getting data, since i have to manually loop in the loop function every now and then which is slow i believe.
Can you please help me?
Thank you.
How does my hardware pin state changes immediately when state of blynk button changes?
Does it my hardware knows when button state changed ?
Again checking it state in a interval time?
I have come across below subject as i wanted to achieve the same. But some how its not working through blynk servers so i had tried with thingspeak as cloud server but its slow.
The difference is that your reference to button / pin changes all relates to a single server i.e Blynk’s whereas the webhook invloves a second server i.e. thingsspeak server.
If the data is actually changing every 15s on thingspeak then simply set up a 15s webhook timer in Blynk.
The thing is that i wanted to implement voice commands to switch on and off device though IFTTT.
I was successful with thingspeak but the time between voice acknowledgement to the real action performed on the board is long like few secs … But after seeing how blynk updates values very fast with their cloud … I wanted to use blynk cloud to do the same IFTTT thing for better response.
