New NodeLink User - Install On Raspberry PI 3b Help

Recommended Posts

I found a Ventstar Thermostat T7900 at a great price and finally broke down and bought it.  I am now going to install NodeLink.

I downloaded the script but I noticed that it references the pi user home folder quite a bit.  I actually modified the pi user to a different user name (mostly for convenience, but it works well with my other things I am doing with my RPI's.

I assume I can simply update the script to reference the new home folder name, but thought I better ask @io_guy and see if there is anything I should be concerned about?

I have my RPI imaged, so I am not to worried about screwing it up...so going to give it a shot.  Please let me know your thoughts.

Thanks.

I got it installed and running and connect to ISY.  I couldn't find and documentation to tell me how to setup the Venstar T7900 with it, put it  seemed fairly intuitive so I went about it.  I did get it setup.  It resides on a different VLAN in my network then NodeLink does, so at first I was getting a couldn't connect, I realized I had to open the firewall, which I did.

Now I get the following error:

Venstar: Get Error - Connection refused [ven1]

Can you point me in the right direction as to how to get it connected?  I saw a reference to a "How To" but couldn't find it.  Any documentation out there I should be reading?

Thanks for the help.

@ulrick65, on your Venstar, you may need to turn on the local API to get the thermostat to talk to NodeLink: Menu | Wi-Fi | Local API Options | Local API - ON 

That did it!  Working like a champ now!

Now I just need to figure out how to get my firewall setup so I can re-enable it and only allow NodeLink to Talk with Venstar through it.

What specific protocol and ports does it need?

Thanks @Bumbershoot   Man...I love this forum!

Looks like plain old http (port 80) to me:

Ok, have to mess around and figure things out...but first thing is to get Alexa to set the temperature.  I am sure I can do it through Venstar Skill (havent looked) but I can't see how to do that in ISY?  Alexa does not recognize the device as a Thermostat...like it did the old one.  Am I missing something here?

Thanks.

I use the Venstar skill, but you have to have a Venstar Skyport account to use it.  The account is free, and it works fine with Alexa.

Yea, I fired it up after my last post and works great!  The only thing you can't do is change modes, which is easily done in ISY.

Great stuff...works like a champ!
