[SOLVED] Controlling Linux client with MQTT (or other possibilities)

[rkrisi (Kristof Rado)]

Yes, it is similar in OH HomeKit addon, first you have to add a ‘Bridge’.
Thanks, I’m really waiting for it Yes I’m hooked I already love this thing. Setting up to control through mqtt and even get responses on different topics took me 10 minutes or so…

And seeing in the HomeKit addon that I can add my AirPurifier and other things to HomeKit and have it more stable is what I’m waiting for Anyway if you could include in the example, where you can find that which device type accepts what kind of data (for example.: Air Quality Sensor accepts Number formats? Air Purifier accepts ON/OFF switch or also a Number with the RPM?)

Thank you!

Hint for seeing what is available for any item:

Make an inject node that looks like this and send it right into a homekit item:

Then check out the “debug” in node-red where it will list all items available for that item (air purifier for your example).

This will make more sense in a little bit when I get my examples loaded.

…standby…

I have just changed a couple of pi-zeros from python scripts to node-red. Easy to maintain. Reliable…

Good idea…

Here’s one of each of my item types.

I actually am at 50 HomeKit items in node red these days…

My node-red + HomeKit + OpenHAB setup

I know others have connected their devices and everyone has their own twist on how to do this. My preferred method is to use function nodes wherever possible. This keeps things from getting too messy with all of the switch and change nodes that come up in similar setups. It came up today when I started showing @rkrisi how to use MQTT+Node-Red to send command line codes to other computers. So here goes. A couple of prerequisites: -Install node-red (obviously) -Add the flow “node-red-contrib-h…

The ads1115 is connected to the pi via i2c

[crxporter (Garrett Porter)]

So yes - go to “manage pallet” in node-red on that pi and search for ads1115.

This is the result I get - I can’t try it but you should be able to install this flow in node-red and be running pretty quick.

ncd-red-ads1115

the other question . would I be able to read rs 485 and send the information to my MQTT and then to openHAB . this is the unit I am looking at .

MISOL Weather Station - RS485

@allen

would I be able to read rs 485

Seems like yes? Node-red can read serial input/output on a pi. You’d only be limited on your ability to program node-red to read the data.

You’ll need the “Serial” input node in node-red.

I don’t have any serial devices so I’d be useless in figuring that out. The node-red forums may be a good place to start - just have to find someone who has used one of those devices…

Thank you alot.
