Listeners are important to save data traffic when we want to send commands from firebase to the esp32. They work fine if are not more than 3 or 4, but when we try to implement several listeners, let's say 20, esp32 starts crashing. What would be a work around that allows sending different commands to esp32 without requiring some data expensive strategy like using recurrent "get" functions?
Hi I have an issue with the token of my auth in the firebase ,whenever I upload the code it gets uploaded I get my desired output on the serial monitor but it also gives me a message of "FAILED REASON: token is not ready (revoked or expired)" however I tried making a whole new Database your way but this didn't really help me , Do you have a way for that?
Hello. I watched your Arduino IDE+NodeMCU V3 with RFID RC522 video and I have a problem. I can't get the home ok ok image which is the database website home page photo. Can you help me?
All your videos are great but I could only confirm from these webserver database videos that they are meant for intranet only i.e. these projects won't work through the internet from remote location. So, I'll be very helpful to you if you could make a detailed video on the database server reading sensors data and controlling appliances using NodeMcu (ESP8266) through the internet from any remote location.
great video, thank you. I have one question, is there a way of using the snapshot notification for subscribing to a value in Arduino and avoid to polling the database?
