From this

#define relayswitch 7

You can't use GPIO7 because it uses as MISO of SPI bus that connect with Flash memory. Your device can't run and program because no data to/from flash memory.

For query, you must and always assign orderBy as states in Firebase document, like this.

QueryFilter query;
 query.orderBy("id");
 query.equalTo("esp.2615");
 query.limitToLast(1);

You may get error like this return from server.
connection refused, Index not defined, add ".indexOn": "id", for path "/arushpass/cool/chill", to the rules

You also set the database rules like this by use wild card $ to any dynamic child keys of user_key which can be room1, room2,... and their child key $device. The name that use with $ can by any what you want.

 "rules": {
    ...
    ...
    ,
    "user_key":{
      "$room":{
           "$device":{
                ".indexOn":"id"
           } 
       }
    }
  }

or use only one wild card $ to refer to any child keys under user_key included room1, room2, device_name and so on.

 "rules": {
    ...
    ...
    ,
    "user_key":{
        "$device":{
             ".indexOn":"id"
       }
    }
  }

Thanks for the quick reply

My user_key, device, room can be changed or deleted so do I have to edit the rules every time it is deleted or updated ?

from firebase-esp8266.

Yes but it better to have permanent parent key.

from firebase-esp8266.

Oh

So can I set my rules like this:

"rules" : { .... .... .... , ".indexOn": "id" }

from firebase-esp8266.

This means id is the parent key at the root of database and sort or select is no effect, indexOn should set to childs.

Thanks

One more question:

Is it normal that when I am streaming I cannot execute Serial.println()

from firebase-esp8266.

Don't understand. But don't serial print continuously like that, mcu needs idle time to feed the watchdog timer or handle WiFi task too, if you do that wdt reset may occur (only when connected to PC).

from firebase-esp8266.

Oh thanks

BTW can I use GPIO4. In the pinout it tells GPIO4 is not used

from firebase-esp8266.

Yes, you can see any esp8266 dev board like this what the pin you can use
https://wiki.wemos.cc/products:d1:d1_mini
Some can be multifunction as basic GPIO and communication port as SPI or I2C.

Thanks man
I'll try it now and tell you

from firebase-esp8266.

I am getting:

not connected
Stream timeout, resume streaming...

and after I edit my id the relay does not change it's state

from firebase-esp8266.

Your internet problem or something. Begin stream may fail in setup. What's about code in loop?

from firebase-esp8266.

Did not understand, did you ask code in loop?
I have not changed it a bit

from firebase-esp8266.

Try the examples
https://github.com/mobizt/Firebase-ESP8266/blob/master/examples/Stream/Stream.ino
https://github.com/mobizt/Firebase-ESP8266/blob/master/examples/Different_objects_stream/Different_objects_stream.ino
It should work, if any failed, it's your internet or AP problem.
