Tell us about yourself!
After I uploaded program, it's looks like ESP is not running, not blinking, no traffic over serial line. I had to change pins like this:const int trigPin = 5; //D1const int echoPin = 4; //D2Also my HC-SR04is not working on 3.3V, I had to use VV pin instead (there is 5V coming from usb).
Alright, but thanks for tutorial, it's great!
It's working properly, I just didn't understand the functionality completely. Help states:"Run action only the first time the condition is met: Trigger the action if the condition was previously false and is currently true."So if interval is set to 10 minutes, react activates, then wait 10 minutes, check if condition is false (incoming data) and only after that, new react action can be triggered. In other words, there have to be false / true / false transition (with minimal time of 10 minutes between transitions).
Hi,I got issues with react on Thingspeak. It successfully run once, but after uploading new data and disable uploading, react wont run (last run time is still the first one). I can see that new data were upload after first try, then there were no data for 4 minutes (condition is set for 1 minute). In help file it states: "Every 10 minutes: Test every 10 minutes, on the clock. For example, a React created at 10:08 a.m. triggers at 10:10, and every 10 minutes after." So if I upload new data and then in 11:00 if there haven't been any new data for 1 minute, react should activate, right? When I recreate react, it works again, but just once.
