Centralized Relay conteol

Hi, 

     I am new to this site but found some exciting products that we can use. I volunteer for a non profit organization where we would like to automate our outside lighting control. Here are the requirements:

- need relay boards

- need wireless capability

- all relays need to be controlled from a centralized location available within organization network or outside

- need to be able to schedule them to turn on off 

- need to be able to manage, view status and change status anytime from a central location

I have looked at the fusion 4 and tried to purchase one of the relay boards with wifi option but there are other things like USB modules etc that I am not sure whether to get them or not. We have multiple locations throughout the site that need to be controlled so will need many relay modules and would like to keep the cost to be minimum. 

Can anyone provide me a combination of hardware and software and guide me on how to get started and most importantly how to create centralized control. 

Thanks in advance. 

Regards

Jack.

Hi Jack,

My question wuold be what exactly do you mean by "all relays need to be controlled from a centralized location"?  Do you mean a computer on a network which is connected to all of the relay boards on a local area network?  Or does this setup require internet connectivity becase not all boards will be on the same LAN?

Dear Travis, 

    Thanks for your quick reply. I am sorry if I wasn't too clear. We would like to connect all relays wirelessly to our network on site and we are envisioning to have a central web page or a program that would allow us to display all of the relays on one page, view thier status and change status anytime. So, anyone on our network on site would be able to access certain web page or a PC where we can access them all at once. We don't want to have go to specific device at one and change/view the status. 

Please let me know if you need clarification on any of this. 

Thanks again.

Hi,

Do you happen to have any in house web developers?  This could absolutely be done using something like PHP, Node.JS, etc but we do not have an off the shelf web gateway that allows you to control and set on/off timed events on the boards.  This is something that would need to be developed.  If you could develop that web application then our relay controllers should work very well with it.

Travis, 

     We do have developers that can program in these languages. Could you please provide me a what products would we need to try out to control wireless and list of commands or tutorial to program? 

Thanks.

Hi,

If you only need 1 relay, are switching a relatively small circuit, and can connect the relay via WiFi to your network then I would recommend taking a look at this board and purchase it with the optional WiFi communication interface module:

You only need to establish a TCP socket connection to the board over port 2101 and then pass the commands outlined in this guide:

If you or your developers have any questions on this please let me know.

Thank you,

Hi Travis, 

      I mentioned purchasing one relay for now to try it out. We eventually will need to buy many more. Should I get the proxr relay instead of proxr lite since your site mentions that proxr lite is limited to 8 relay control vs 256 on the proxr. If it is true then can you point me to a single simple wifi relay with proxr capability?

Thanks.

Hi,

The ProXR and ProXR lite controllers use the exact same command set.  This means you could purchase a ProXR Lite board, develop and test your software, and then integrate a ProXR board later on without the need to alter your software.  ProXR boards have an expansion port for additioning additional relays on via expansion boards, ProXR lite boards do not have that expansion port, but that's the only difference.  If I were you I would get a 1 channel ProXR lite board to test/develop with, perhaps maybe a 4 relay board just so you can test software with additional relays.

Thank you,

Travis Elliott

Thanks Travis. I will get one of the lite ones. Also, do proxr boards have capability to have on board timers to turn relays on/off? 

T

Hi,

Yes, ProXR and ProXR boards have built in timer commands.  They are outlined in the ProXR guide here:

... And so as proxr lite?

Hi,

That guide is relevent to ProXR and ProXR lite.  They take the exact same commands.
