Build your IoT Dashboard with InfluxDB Cloud, Grafana | Full setup with Nodemcu

In this session, I have discussed, how I connected to InfluxDB Cloud v2 from nodemcu and visualize our data there. I have also used Grafana to visualize our sensor data through Influxdb v1.7 running locally.
Full Code: github.com/jigneshk5/IoT-dash...

1. Setting up InfluxDB Cloud v2 : 12:30
2. Arduino code discussion of InfluxDB Cloud: 17:49
3. Building InfluxDB Cloud v2 dashboard: 36:49
4. Arduino code discussion of Grafana: 47:18

Correction At 23:10 , Its calculating the time as the cloud server connection verifies the certificate expiry as its connected to SSL based server (Influxdata)

Nice work man! A well-deserved star in your Github repository for this project.

Thank you

I keep getting a "connection refused" error. I have double checked bucket, org, and token and it is all correct. Do you have an idea to why this occurs?

[@rahul.chandrashekar]

How do i create tags? i have create the buckets - but how do i create a tag in InfluxDB2

[@vladlenbezymanny3716]

Good day.
Thanks for the great video.
Tell me how to export data from influxdb to a csv file ?
Standard output to a file gives me only 20 values ​​in 1 day, although I have a poll every 5 seconds

[@surajnair2315]

I am always getting same data,
the value doesn't change. Any reason?
I am using MPU 6050 accelerometer and a sound sensor. I have Arduino Mega 2560 with Wifi Built in ESP8266 board.

Pls help regarding the time zone of India,what is the time zone we have to add for India?

[@FSISThakurAshish]

Can I access the data of sensor anywhere in the world after configuring the espiot module with wifi and influxdb ,or for as much range as wifi network ?

[@IoTLearner]

You can get the esp module data anywhere in the world as it is connecting to the Internet. You are transmitting data to internet from esp8266

[@FSISThakurAshish]

@@IoTLearner same for esp32 iot module?

[@IoTLearner]

@@FSISThakurAshish yes

[@FSISThakurAshish]

Pls tell what we have to add in timezone for India ?pls🙏🙏

[@rahul.chandrashekar]

i am able to connect to my bucket - but there are no tags - how do i create tags? is it via Telegraf ?

[@rahul.chandrashekar]

i figured it out - user needs to add "Data"

[@bhanuduhan9765]

When i upload the code. Ino for influx db serial monitor doesn't show any thingh it jus start showing some sort of characters

[@IoTLearner]

Change baud rate of serial monitor to the one you mentioned in X in your code.
Serial.begin(X)

[@bhanuduhan9765]

@@IoTLearner i have already done it but still it showing error

[@generalknowledge9555]

ESP 32 with used to connect water flow sensor. This sensor value is stored in the InfluxDB database. while the below-shown Arduino code is removed we can get the correct accurate flow rate. But in this code is removed, then data can not be sent to the InfluxDB database. (water flow sensor is connected with an interrupt pin).
if (!client.writePoint(sensor))
{
Serial.print("InfluxDB write failed: ");
Serial.println(client.getLastErrorMessage());
}
Please give me the correct solution as soon as possible. It will be a big help for me.

[@syahrudi7702]

Please...How to fix the trouble I got error in serial monitor :InfluxDB write failed:{ code: forbidden,message:insufficent permissions for write } .Nice your tutorial

[@IoTLearner]

Check the token of the bucket in Influxdb cloud, you should give it read & write access, see 14:44

[@syahrudi7702]

@@IoTLearner yes that is right,now i can write data to influxDB and thank you very much! for your support!.

[@chitzo17]

cant use test db on grafana, can u tell me why?

[@IoTLearner]

01:08:50 , First set your testdb with grafana

[@jaypatel27]

Do you have any idea how to communicate InfluxDBCloud to Grefana

[@IoTLearner]

Please check if Influxdb cloud provide api to make it connected with grafana....

[@jaypatel27]

@@IoTLearner Do you have any ref. for cheap cloud dashboard for IoT with user management?

[@IoTLearner]

@@jaypatel27 you can use ubidots or Adafruit.io

[@SamAlifTech]

Can I write data to InfluxDB for every 1 second?

[@IoTLearner]

Yes you can, set the refresh rate in influxdb cloud accordingly

[@SamAlifTech]

Also same if I want to upload it to grafana?

[@nitishgowrydoss6959]

Hello. Can you make a tutorial on how to send ultrasonic sensor data from arduino uno to esp8266 via serial communication and then send that data to influxdb ?
This one is a very nice tutorial. Thumbs up for that.

[@IoTLearner]

Sure, I will cover this in some live stream...Thank you

Can we upload two code file to esp

No you can't, you have to merge them then you can upload
