MQTT values to send e-mails.

[PandCall]

Hello nickiv,

My new extension to my project "SMS Gateway"
I have values coming in from a “Home Assistant” form.
I monitor MQTT with NOD-RED

I filter my conditions
`
// Récupérer les valeurs des entités
let tempNumber = flow.get('temp_sms_number') || msg.payload;
let tempMessage = flow.get('temp_sms_message') || msg.payload;
let smsNumber = flow.get('sms_number') || msg.payload;
let smsMessage = flow.get('sms_message') || msg.payload;

// Stocker les valeurs dans le contexte du flux
if (msg.topic.includes('temp_sms_number')) {
flow.set('temp_sms_number', msg.payload);
} else if (msg.topic.includes('temp_sms_message')) {
flow.set('temp_sms_message', msg.payload);
} else if (msg.topic.includes('sms_number')) {
flow.set('sms_number', msg.payload);
} else if (msg.topic.includes('sms_message')) {
flow.set('sms_message', msg.payload);
}

// Comparer les valeurs
if (tempNumber === smsNumber && tempMessage === smsMessage) {
// Les valeurs sont identiques, envoyer le SMS
msg.payload = {
number: smsNumber,
message: smsMessage
};
return msg;
}

// Si les valeurs ne sont pas identiques, ne rien faire
return null;
`
At the output I have this

My question is: how can this information be reused in the node SEND SMS ?

Phone Number and message ?

How do I forward my variables to the SMS SEND Node?

Regards

Hi, @PandCall !

To get what you want please set message as msg.payload, and Phone Number as msg.phone. Like this:

msg.phone will override Phone in node settings, though it is required to fill this field anyway. Set it to your phone number for instance, or some bogus number. In the latter case please make sure to always set msg.phone not to spam anyone😁

Please let me know if it worked!

Hello Nickiv,
Thanks for your feedback
In principle, it's good, I've managed to do the shipping with this set-up.

Make sure the number is a string and begins with +33 or another country code.
Now I have to look at how my Payload is processed, because I'm losing information.

In France we use short numbers without the +33, for example to get away from spaming, and I need to be able to forward this type of short number.

In Debug after SMS SEND Node
I have this information, probably the acknowledgement of receipt of the shipment.
Would it be possible to obtain more information about the shipment?
Something more complete to identify exactly what happens on the way out?
For example, in your SMS SEND Node, add a check mark to display the debug?

Now it's up to me to adapt the processing of my Payload string that arrives from my form.
But your information has been invaluable in understanding the processing.

A couple of things you should consider:

1. My module is simply a wrapper around the HTTP methods of the modem. If you log in to the modem's web interface (http://192.168.8.1/) and try sending an SMS from there, it should have the same effect. If you're able to send an SMS to a specific number through the web interface, it should also work in Node-RED.

2. Keep in mind that OK isn’t always reliable. For example, if your SIM card has no available balance, it may still return “OK,” but the message won’t be delivered. At least, that’s how it behaves with my mobile provider.

3. I’m using three modems connected to a Raspberry Pi, and unfortunately, they sometimes hang — the only fix in those cases is a reboot. So I had to implement some alerts to detect such failures. It happens about once a month, which is acceptable for a smart home setup, I suppose. But if you need something more reliable, take a look at the Yeastar TG200. It can be integrated with Node-RED and gives you more control over messaging. It also works in real-time instead of relying on polling. Just make sure to check whether your provider supports it and whether it works with your LTE band: https://www.yeastar.com/voip-gsm-gateway/

nickiv,
I fully understand all the limitations.
I just ask the questions in case :)
But your module helps me a lot, and I use it in a personal context, so like you, I accept certain constraints and difficulties.
But if I compare the gains with the hassle, I say bravo and thank you.

nickiv,
It's perfect, everything works the way I want it to.
Would you like me to publish the details here for others to use?
Many thanks for your help and contribution.

You are most welcome 🤗
