@bbartling this seems to be a very relevant topic. Others have expressed interest in this too, as well as integration with Normal Framework. I'll definitely take a look as time permits, but will happily accept pull requests from contributors as well. Something written natively in javascript would be preferrable. Maybe https://github.com/BiancoRoyal/node-bacstack?
@joyja thanks for the response! So at least in the Node Red community that Node Bacstack didn't support BACnet over Rs-485 (BACnet MSTP) and I found it so hard to use that I ended up just creating a rest API app to run along side of Node Red.
I'm not a JavaScript guru so it was easier for me to just use Python BACnet stacks what I was used too.
I also have a rest API BACnet gateway git repo, is that something that could be used with tentacle? Curious on your thoughts, I need to build in a simple rest authentication feature but the app has been tested. Would you have any recommendations for rest API authentication that I can build into my app?
A BACnet MQTT gateway would be interesting too.
Well I couldnt help myself I added http basic authentication to the BACnet rest API app. Curious to maybe play around with tentacles.
Is the rest API features ready yet for tenticles?
I would be using it for research work related to continuous electrical load management in buildings. Its non profit research funded work, simple stuff adjusting HVAC setponts in a building to control electrical usage by the cooling systems/chiller
Hi @bbartling sorry I'm only replying now to this! Distracted by other work. Yeah I wasn't taking into account RS485 devices, trying to handle the TCP/IP case first. Do you use RS485 often in the building industry? I think it's a great idea to use what you've built via the REST API. I don't have a REST API source in Tentacle PLC yet, but this gives me some motivation.
Your use case sounds like a great application for this.
@joyja, hi yes to the RS-485 devices. There is a lot out there for sure even though the industry seems to slowly slowly be converting TCP/IP type devices. I have one of these on my test bench: https://www.ccontrols.com/lp/routers.htm
So the rest API app definitely handles RS-485 but needs to be through a BACnet router which is the gateway between TCP/IP/RS-485. These devices are super common in the building automation world and built into supervisory level controllers and some field level devices handle BACnet routing too to RS-485 networks...
I have never seen for IoT in smart building industry an IoT device that is hard wired into an RS-485 network. Just need tools that can route data to RS-485 which we can do.
Well Ill check in with you for when rest API can be tested : )
Could BACnet protocol ever be implemented with this project so the HVAC controls contracting industry could use this too? Problem with BACnet the JavaScript library's may not be evolved/maintained very well. Its a big problem in the Node Red community. This project below I think could be promising but a little over head on how it could be implemented:
BACnet Stack
If there was ever an opportunity to test BACnet with tentacle I'd love to be involved.
