Sonoff/Homekit/Dashboard switches synch'ing

[877]

Hi all, first post so be nice

I've been using node red a few weeks, and have little knowledge of JSON at present. From the posts I have been reading I may be out of my depth!

Could I get your thoughts on this flow, it works fine but is it good practice? i.e. is there a more simple solution I am missing?

There is a dashboard switch, a Homekit switch on iPhone, and the physical switch on the Sonoff (Tasmota firmware). Pressing any button toggles the Sonoff output, and dresses the other switches.

Thanks for any pointers!

As long as you don't see any loops and it is working, it looks fine.
I realised myself that a dashboard switch, while having homekit on both mac/iphone/ipad would be a little redudant

Hi @bakman2 there aren't loops, all is good. I don't really understand the functions though, I googled and read but don't get it - yet.

1. It seems the homekit node needs an 'object' called "{"On":true}" or {"On":false}.

2. The Sonoff seems to need a boolean true of false to operate.

3. The function has the code "return { payload: msg.payload.On };"

I can't see how that changes the payload from a JSON object to a boolean true/false. I might be totally misunderstanding it.

I'm still deciding what to use for my main display, I have a spare iPad mini 4 which I was thinking of using. I'm torn between dashboard, homekit or Blynk...

[bakman2]

The homekit node produces {msg.payload.On} (true/false), in your function node, you are "reading" the value of msg.payload.On and sending it to mqtt, this is the hint: you don't need the function node, just connect the homekit node to mqtt directly. (if the sonoff accepts true/false)

[877]

I will check that, thanks for the explanation. I think it didn’t work first time without the function node, but there is a bug with HomeKit-bridged where node red needs restarting before the HomeKit node will work correctly. So it might have been that.

Hi, I'm quite new to Homekit on Node Red. I'm trying to use the Homekit node (not the Bridge), with a Sonoff-Basic and MQTT into the Homekit node. The Sonoff provides 0/1, and I used the Change node as above to change to true/false. I don't however understand the required format. After numerous attempts, I get a range of messages ranging from "payload does not expect a Boolean", "integer", "string", etc. What exactly should the input be for STATE into the node?

see the ReadMe for the node on flows.nodered.org. which contains the general format, and a suggestion as how to check the specific format for the hardware type you are using. Generally they expect msg.payload to be an object.
