Count IoT devices without data and used this information as filter.

Hi all, 

We have a lot of IoT devices installed. 

Some will not send data to cloud due to contact problem/configuration problem.

IoT ID	Voltage	Current	timestamp
1	1	2	19.01.2023
2	1	2	19.01.2023
3	2	2	19.01.2023
4			19.01.2023
5			19.01.2023
1	1	2	20.01.2023
2	2	2	20.01.2023
3	1	2	20.01.2023
4			20.01.2023
5			20.01.2023

I would like to have
1. a list of ID (in this case ID 4 and 5) of those IoT devices and count number of IoT devices which is not sending data to cloud

2. exclude those ID numbers in calculation to have better efficiency. 

if I do intergral of battery current, I can exclude ID 4 and 5 to save computing data and time. 

Thanks in advance!

Best regards

sorry for confusion.

number of rows with voltage <2V

@reynold522please share sample output in table format?

@Mahesh0016 

thank you for your question

e.g., count number of points with voltage<2 from each IoT ID. 

Thanks in advance!

@reynold522 please can you explain what is point in sample data.
