Welcome to the forum @Ideasbuilders

Response to what?  
What hardware are you running on? Pi zero or super computer or something in between.

> [@Ideasbuilders](#):
>
> Any recommendation for data storage program for keeping data

What sort of data? Time series? Employee details? Word documents?

> [@Ideasbuilders](#):
>
> Can node-red setup multi devices

What sort of devices?  
For the maximum, again it depends on the hardware you are running on. Also on how the devices are accessed.

>
> How to setup for multiple users?

What do you want the users to be able to do? All work on the same flow development? Access some sort of real time process dashboard display?

Hardware im running is a IOT device with modbus communication.

Basically sensor data with time for IOT application.

For multi hardware will be the same IOT device with modbus.

For users, will be acessing dashboard, data with multiple level of permissions.

Node-red cannot do this.

Hi @Ideasbuilders - welcome to Node-RED! Some of the requirements you mentioned are not possible with Node-RED currently, but are possible with FlowFuse: multi-user management with RBAC, device management from a central dashboard, persistent context/data storage, and multi-user dashboard is on the roadmap as well.

FlowFuse was founded by the co-creator of Node-RED to layer business critical capabilities on top of the open-source NR platform.

Here is a link to our site: [https://flowfuse.com/](https://flowfuse.com/)

Let me know if you would like to discuss further!

SO if I understand correctly you are asking what the performance will be running on a device for which the spec is unknown.

How have you installed node-red on the device?

No, I'm just using as computer as the node-red host. The device just provides readings and control via modbus.

In that case the limiting factor will probably be the modbus comms, not node-red.

For data storage look at influxdb.

What data do you need to store and what are you going to do with it after storing?

The data will mostly be timestamp, source and values, will be access afterwards for analysis

I already gave you my recommendation for that - influxdb.

How about multiple users access at the same time?  
Is there a limit?
