#define FIREBASE_HOST "esp8266-fbd9c.firebaseio.com/"
#define FIREBASE_AUTH "serect_key"
#define WIFI_SSID "SSID_name"
#define WIFI_PASSWORD "password"

The firebase Host is wrong the correct way would be (w/o final slash):

#define FIREBASE_HOST "esp8266-fbd9c.firebaseio.com"

ghost · 2018-01-03T05:10:24Z

@JuanPTM
Even after removing final slash it failed.

how to create a firebase parent node?

JuanPTM · 2018-01-03T14:51:35Z

I think, your problem is still about configuration, because that is the example code.
It may be you are using the wrong secret for the connection.
You can check your secret following the next step:

Click on "Project Settings" of your firebase project.
Click on the Service Accounts tab
Click on Database Secrets
Hover over the non-displayed secret and click Show

As I said before, the example code is working on the ESP8266, at least until a week ago or so (I dont have an ESP8266 to prove it right now).

proppy · 2018-01-31T07:49:21Z

@JuanPTM Thanks for answering this question :) @ghost do you still have issue with the library?

MandelbrotMan · 2018-02-01T04:15:37Z

Im having the same issue as well. I found the secret key for the database but it says that its been deprecated and that the code needs to be updated with the firebase admin sdk. However the most obvious ways are only for android, ios, and web applications....

bryan0805 · 2018-02-03T02:58:19Z

Does anyone show this error below and how to fix it

Jackfr0zt · 2018-02-12T02:15:02Z

@JuanPTM sir there is possible that there is a problem on circuit that's why it failed? can you help me? i have the same problem above.. im using arduino uno and esp-07.. i connect it to 3.3v in arduino pin to my esp.

JuanPTM · 2018-02-13T16:39:58Z

@Jackfr0zt sorry but i can't help you, I've never use an ESP with and Arduino UNO, just used a NodeMCU or WEMOS.

johnandersen777 · 2018-02-20T16:46:44Z

Looks like Database Secrets is deprecated. Anyone know what is takes to use a non-deprecated method?

trovaolerdo · 2018-02-27T14:31:42Z

any updates on the firebase-arduino?

heriveltogabriel · 2018-03-13T20:25:47Z

I'm having the same problem, I downloaded it again, updated but it does not work.
Someone?

MandelbrotMan · 2018-03-14T23:58:41Z

Ive had that issue and changed the arduino ide to a older version. I think 18.3

SharanIoT · 2018-04-17T14:24:42Z

@JuanPTM
I'm struggling to make the firebase example running on my Wemos D1 mini(esp8266). I always get setting read/write error. I tried everything that's available on the online forums with no luck. Are you sure that Google still allows to use the deprecated secret_key inside Database Secrets?

Any help would be a great help.

Thanks,
Sharan

vivekaris · 2018-04-17T17:30:07Z

I have successfully tested on Node MCU
I love to help anybody.

kulwant96 · 2018-04-17T17:35:22Z

Just try to download your library again and upgrade your ide. Hope that ll work

SharanIoT · 2018-04-18T11:20:09Z

@vivekaris You tested recently? If yes, then Wemos D1 has problem with firebase?

SharanIoT · 2018-04-18T11:21:48Z

@kulwant96 I tried that many. Didn't help. I started doubting my Wemos board ability to support firebase.

vivekaris · 2018-04-19T07:07:36Z

As per my research most of 8266 code not compatible with wemos D1. Try is on node MCU .I will try to help.

SharanIoT · 2018-04-19T08:08:23Z

Folks,
FYI, finally I'm able to run the firebase samples successfully on Wemos D1 Mini. I think firebase library has a dependancy on arduinojson library. Once I included it, everything went smooth.

Thanks for your inputs.

kotl · 2018-04-19T12:36:31Z

Never had any problems with D1 Mini, in fact it is the most used controller for me.

And FYI, this is in the main readme:

Dependencies
FirebaseArduino now depends on ArduinoJson library instead of containing it's own version of it. Please either use Library Manager or download specific version of the library from github.

proppy · 2018-06-15T14:16:06Z

Filed #349 to improve error messaging, I hope it can clear some of the issues reported here.

Change your firebase url in your source

Don't include http: in your source file of firebase url statement

Example:

#define FIREBASE_HOST "myfirebase-url.firebase.com";

Don't include http in url
Hope this helps
