Is it possible to auto update the Thingspeak Channel data at certain time?
I want to use a microcontroller and esp8266 to control the relay and home appliance. For example, my water pump needs to be "ON" from 6 am to 10 pm and "OFF" from 10 pm to the next day at 6 am. In this case, I want the thingspeak channel's field to auto-update "1" at 6 am and auto-update "0" at 10 pm. I wonder if there a possibility. If it can be achieved, my esp can receive the latest data to control the relay and appliance.

I recommend using the TimeControl app linked to a MATLAB analysis that uses thingSpeakWrite() to update the channel value. The getting started tutorial shows you how to set up a recurring time control. You might have to use two time controls, one at 6 and one at 10. Alternatively, you could run the timeControl every hour and check the time and use a conditional to decide what to do if the time is correct.
if hour(datetime('now')==6)
%pump on
end
if hour(datetime('now')==10)
%pump off
endBy the way, If you are going to put the esp to sleep in between actions, Ive found the ESP32 to be a lot more reliable in this kind of application.
Very much possible. Timer function of the controller needs to be used for generating the trigger. Also, a RTC is required for getting the real time information. It is a straightforward task.
