This is REALLY interesting. Before I try to deploy something I have a question: I have node-red installed on a raspberry PI with openhabian and I have the homekit service enabled (and working) in openhab. Can I have both services up and running on the same box?
You can absolutely run OH and node-red on the same box.
The response of node-red is lighting fast
Although I don’t use homekit (I stay away from Apple as far as possible…)
I have been using node-red as a parallel rule engine for some rules especially for scheduling as this is lacking in OH
It is also using Javascript with is simple and very type tolerant unlike OH where sometimes we have to jump through hoops for simple type conversions.
Just a bit of warning though.
If you restart OH then the OH nodes in node-red will disconnect and you will need to do a full deploy to reconnect (But not all the time)
You also need to put some delay in initializing values/nodes in OH if required because node-red will start before OH has finished starting after a reboot.
So basically I will find two bridges in Homekit, one for openhab and one for node-red, correct?
Don’t know, don’t use homekit
node-red doesn’t present a bridge, it presents individual HomeKit “accessories”, which are like openHAB things. Individual Accessories can have multiple services, which are like openHAB channels. So for example, my lock shows up as an accessory in HomeKit, and shows locked/unlocked, how the current state happened, and what the battery level is, which are separate OpenHab items tied to channels of the lock thing, mapped to services of the lock HomeKit accessory in Node-Red.
Hi,
because I think in the thread is more going on regarding this maybe worth posting…
I posted two function-nodes in this thread for the color-item<->homekit-transformation.
As my codingskills are more on the zero-to-none-side maybe someone can check if it’s ok or if it can be done much better. And maybe it helps someone which would be nice as I could give a tiny little bit back to this helpful community.
Hi. I’m new to node red so i need some help.
so i got a homekit node set as lightbulb. and it send msg to mqtt.
i believe a need a function to convert my payload from homekit to a string for my mqtt. can anyone help?
TY
I’m curious, do you have speed control on your fan at all? I’m trying to figure out what commands Siri supports for setting fan speed. I’m currently using a GE fan switch, which acts like a dimmer on HK which means instead of saying “LOW”, “MEDIUM”, or “HIGH” for speed I just manually set percentages (i.e. 10%, 50%, or 100%)
@rswennen, this is some great find on this one! Kudos!!!
I just finished installing and configuring Node-Red. I did eventually figure out how to get Node-Red to show accepted info fields.
However, I was trying to configure the sensors off my bed (SleepIQ) to trigger in Homekit. I have them working just fine in OpenHab, and up until finding this, I just had them configured as items with Switchable in OH with the Homekit service. However, this had them showing up at actualy on/off switches and I need this to be a read only parameter.
I used the Occupancy sensor in NodeRed, but for some reason I can’t get it to show the changes in Homekit.
Thoughts?
I definitely think that with a bit more details this can become an excellent guide and solution for HomeKit integration with OpenHab!
To OpenHab developers:
Since this obviously is possible I really think having this capability embedded in OH by extending the existing Homekit integration would be HUGE!!!
Thank you,
Moshe
Thanks for your tutorial is great.
I am a noob bit I succeed in creating simple flow from OH to Homekit and viceversa.
I am not able to transfer a float from homekit to oh. Can you post an example?
I want to transfer the target temperature from homekit to OH
Nice to see that I’m not alone in doing this.
Here is my Fan control flow. I use the LIRC binding to control a Bionaire Fan, and I’ve added oscillation and speed, as well as the default On/Off.
Code if anyone is intrested

Really nice work. Just one question I’m struggling in how to send a temperature to home kit.
I have this item
Number HueTemp "Hue Temperature [%.0f]ºC" (Temp, Sensors)
and have no clue how to send the temperature to the HomeKit node the answer is always invalid payload string object
I have used a change node but no clue from what to what I must change. My guess was
{"CurrentTemperature":msg.payload.state}
but it didn’t work.
Any suggestions?
Thanks
I do it with a function node.
msg.payload = {
CurrentTemperature: + parseFloat(msg.payload).toFixed(1)
};
return msg;
Hi @ptweety,
may it be possible that you share your Flow-Code of your implementation for the heating thermostats? I’m in trouble with the conversion from the HomeKit item to the values for open hab…
Greetings

Hi @n30ngruu3n,
it took me a while to find the flow since I’ve moved my nodered stuff from one machine to the other weeks ago.

[SOLVED] Missed out on the fact that npm version on my raspi was super-outdated.
Uplifted to most recent - all good now.
Are you using Openhab with Homekit binding and Node-Red on the same server?
I did install Node-Red and followed your how-to (kudos), but none of the homekit accessories created in node-red are found by Home App - any advise how to resolve?
I used to run all on a rpi but recently migrated OH and node red to docker containers. So should not have any impact at all.
Haven’t come across any issue like that. Would it be possible your NR server with HomeKit is on a different lan or segment or your home app can’t see the nr server or some ports are filtered.
That’s the only thing I can think about
