I have a birthday-car which shows nicely all the upcoming birthdays in days. But there is no integration of sensors which gives me the first birthday coming up so I can make some automation or raise a flag to notify me.
So I went ahead and got it done in Node Red (I may move it to a template once I learn more about the syntax in HA vs. what I am used to in Node Red).
I am now able to identify which of the whole list is the birthday coming up first. This is the code for the Node Red function:
//Get length of the array
var arrayLength = msg.payload.length;
//Save the array
var birthdayList = msg.payload;
//Get the first birthday
var firstBirthdate;
//Loop variable
var i;
//Loop through and get the minimum days
if (Array.isArray(birthdayList)) {
//Save the first date for comparison
firstBirthdate = birthdayList[0];
//Loop through the rest
for (i = 1; i < arrayLength; i++) {
//node.warn(birthdayList[i].state + " < " + firstBirthdate.state);
if (Number(birthdayList[i].state) < Number(firstBirthdate.state)) {
firstBirthdate = birthdayList[i];
//node.warn("current is " + birthdayList[i].state);
}
else{
//node.warn("nothing for " + birthdayList[i].state);
}
}
}
msg.payload = firstBirthdate;
return msg;
This is my flow:

I am not able to figure out how to create a sensor in HA called sensor.first_birthday
I am able to get a sensor created called sensor.nodered…followed by a random number.
It only has the following attributes:
It has the state at 9 which is correct, and the icon, which is also correct, the date, weeks remaining. But not the rest. I need at least the friendly_name to know whose birthday is coming up and display it on my dashboard.
So some of the attributes are being picked up. No matter what I try on the Node Red side, adding attributes for entity.id, friendly_name, etc. Nothing changes on the HA side.
In reading about it, there is a config node which adds the confusion. Not a lot of clear documentation about what do do in there or how to set it up. btw, do I need one of these config nodes for each entity I am creating in Node Red?
Here is mine:
Does anyone have a clear example on how to create a sensor in HA using a payload in Node Red?
This is my payload:
Any guides out there I can read to get this done right? Or anyone done anything like this and can give me some pointers?
