Question on accessories giving enumerated values

[ahartman]

I use the homebridge-automation-calendar to determine sunrise - value changes from 2 to 3 - and sunset, value changes from 3 to 4. Can I use such nodes in in your node-red homebridge interface as trigger and conditions?

I can’t see why not, give it a try and see how it works out

I am an absolute beginner and I find node-red + homebridge a steep learning curve. I will try to ask as few 'stupid' questions as possible and I promise to contribute examples of my learning to the wiki to help the next beginner.

This is about controlling the exterior and interior lighting of a medical practice with two inputs:

1. Do we have appointments. This is done with homebridge-calendar, building a ‘fake’ contact sensor, that is normally closed and ‘open’ when we have appointments.
2. Do we have ‘before sunrise’, ‘during daylight’ or ‘after sunset’. This is done with homebridge-automation-calendar; this accessory produces a 2 for sunrise, a 3 for daylight and a 4 for sunset.

Appointments (trigger) can start and end before, during or after daylight (condition). The sun’s position (trigger) can change during appointments (condition).

There are 3 scenes to set: = Morning: exterior lights on and normal white interior lights. = Day: exterior lights off and normal withe interior lights. = Night: exterior lights on and warm white interior lights.

I build this in Homekit/Homebridge with 6 automations: 1 = Start of agenda (trigger) before sunrise (condition): set scene ‘morning’ 2 = Start of agenda (trigger) during daylight (condition): set scene ‘day’ 3 = Start of agenda (trigger) after sunset (condition): set scene ‘night’ 4 = Sunrise to daylight (trigger) during agenda (condition): set scene ‘day’ 5 = Daylight to sunset (trigger) during agenda (condition): set scene ‘night’ 6 = End of agenda: all off

However, using an iPad does not work well as automations do not fire reliably.

I can now do the trigger bit in node-red but I always need a condition as well. My questions: 1 = How do I use the hb-status node to retrieve status? 2 = Does the hb-status node get updated so that the sun’s position and agenda ‘open’ or ‘close’ are correct over the course of the day?

I hope I made the objective clear and all help is appreciated. Regards, ahartman, belgium

Did you close this as you have your answers?

Dear Northernman54, Stupid me, even GitHub is new for me. For now, I am ok as I had a very fruitful afternoon. I may come back later. Regards, ahartman, belgium

Now I have a question. I want to switch on 2 lights, one is dimmable and the other one is a simple on/off light. I want to send {"On":true, "Brightness":25} to the first and {"On":true} to the second one. I do this with a function node with the following Javascript code:

msg1 = msg; msg1.payload={"On":true, "Brightness":25}; msg2 = msg; msg2.payload={"On":true}; msg = [msg1,msg2]; return msg;

The result is that both lights get msg2. What is my error? Please find an export plus screen image of the node-red flow below.

[{"id":"5f3b429e.f3ddbc","type":"function","z":"2f99f1f.d93930e","name":"Set JSON","func":"\nmsg1 = msg;\nmsg1.payload={\"On\":true, \"Brightness\":25};\nmsg2 = msg;\nmsg2.payload={\"On\":true};\nmsg = [msg1,msg2];\nreturn msg;","outputs":2,"noerr":0,"x":380,"y":120,"wires":[["1e95a90a.617be7"],["586fad9a.778514"]]}]

Just send the same command to both, the one that doesn't support brightness will grumble but it is a nothing

[NorthernMan54]

Or try this

var msg1 = { payload:{"On":true, "Brightness":25} };
var msg2 = { payload:{"On":true} };
return [ msg1, msg2 ];

Thank you, I realised I was using the same msg multiple times.

I started contributing to to the node-red-contrib-homebridge-automation wiki. You can go and read 'lights example' 0 and 1. However, explaining without images is hard.

Question: I think images need uploading in some way to GitHub. How do I insert an image in a wiki page?

Question: people may wish to ask questions or comment on my wiki pages to me. Would it be more convenient if I put these wiki pages in my own GitHub account and make links to them on your Node-RED wiki or is that somehow not possible?

Regards, ahartman, belgium.

To put images in the wiki, I upload them to an issue then use the image link in the wiki

[ahartman]

Thank you, that works. How can I center images? Please take a look at my 'Lights example 0' and let know what you think.
