Hi
I want to add users to my project such as I have 3 doctors
each one can use the same project with different mobiles and each on will have different notification
Hello, @eyadalhasan yes you can invite new users in your organization
For example via Web platform:
Settings->users->create new users->invite via email
Also please read docs about limits Limits - Blynk Documentation
You users can download Blynk IoT app from Android(Google Play) and iOS(App Store) and login to this organization after registering via invite link in email.
Regarding settings for notifications, you can read the documentation and topics on the forum
About notification you can read Events, Notifications and the use of "Flag" variables
I do this but no advantage do u think I have to pay ?
It’s your choice whether to buy the paid plan or not. There are prices and limits, you can get acquainted. There is information about what features and limitations are in the plans. And choose what plan you need for your project.
This, and your original post don’t really tell us very much.
It would be helpful if you explained much, much more about what exactly you are trying to achieve and what you’ve tried so far - and the results you are seeing.
Pete.
