Hi all

I have a Nist Supra R3 borehole controller with bluetooth for local control and wifi for connecting to a network. http://www.nistcontrol.com/product/supra-r3-motorscope-upto-37kw/

I am getting started with HA and it looks like the Nist can be intigrated the feetures state:

  • MQTT (sparkplug B), which directs all status change messages to our own free to use remote monitoring website or
  • MODBUS (version 3 RTU) client, which can be continuously polled by a MODBUS server to display the motor status / remote start / stop the controller straight from existing Automation Control software

The last time I asked Nist about intigration with HA, the technician looked at me like I was a Elon Musk creation coming from Mars, their documentation is also very sparse.

So asking as a total HA beginner, is this possible, where do I start, what questions do I ask Nist if I can get hold of one of their software people?

Hi, NIST actually has a very capable technical team. It is MQTT capable and I have integrated into HA via MQTT.

I have an relationship with NIST that is being concluded to supply “value added” functionality to my client base.

The standard NIST R3 will allow you to talk to their server and give you usage data etc. for free. In the past the “paid for” services that they tried to offer were not taken up at all, thus the basic free service offering.

I hope this makes it cllear?

As an aside, if you can get MODBUS going on HA, you can control the controller directly via that avenue.

Hi there, thanks for your reply.
I no longer have the R3 installed, I now have a Trio panel.

I got a new borehole pump, exactly the same 1.5 kW size as the old one, but for some or other reason the R3 and new pump don’t agree with each other. I had a electrician as well as a technician from Nist out to try, but in the end they recommended I install a Trio.

Whether the guy from Nist just wanted to sell me a new controller is up for debate, personally I think he bull shitted a bit and just wanted to sell a new controller because one of the reasons he gave was that the R3 isn’t suitable for 1.5 kW pumps and only much larger pumps, but unfortunately I was not home the 2 days when all of this happened and couldn’t really query it, my mother was alone on the farm and she will believe anything a salesman tell her. I was just informed via Whatsapp while sitting in a meeting, we have to install a new borehole controller, here is the invoice.

What I’ll probably do now is to just install a Sonoff switch or something on the aux input of the Trio to be able to switch the pump on and off remotely. Monitoring the consumption, phases etc. would have been nice, but it is what it is.

The technician mentioned to me they are busy developing a wifi module for the Trio as well which will give it similar functionality like the R3 and I will be able to upgrade my Trio with the wifi when it comes out eventually.
