\"\"<\/figure>\n\n\n\n

Remember the Howto: Snailmail sensor<\/a>? Of course I need a notification on my phone when mail arrives so I can use my old legs and go out and get it. <\/p>\n\n\n\n

I use email and Telegram for this. I also have added a SMS message to but this costs money (to much really) and I like “free”.<\/p>\n\n\n\n

The setup is simple.<\/p>\n\n\n\n

Common<\/h5>\n\n\n\n

The first to do is to listen for incoming events from the VSCP daemon where the mailbox thing delivers them. I could have used a MQTT broker here but have chosen to stick to an all VSCP solution for this.<\/p>\n\n\n\n

The server is the local machine in this case as I have node-red installed on it as well. Well I have about twelve (last count) node-red installations running here so there are machines to choose from.<\/p>\n\n\n\n

The setup is simple<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The localhost is setup as<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

I use a standard setup, just listen on all traffic (no filter), no interface. So at this point I get a lot of events. I could have added a filter here to ease the work for node-red and let the VSCP Daemon do the filtering. But I like when my applications work hard so node-red take care of that task.<\/p>\n\n\n\n

Filtering is the next state. The filter looks like this<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

I filter on CLASS1.INFORMATION \/VSCP_TYPE_INFORMATION_WOKEN_UP<\/a> which is sent when the lid of the postbox is opened. I also filter on the GUID from the postbox device. The GUID from the device is a good example of a GUID derived from a devices MAC address. It is built from a template like this<\/p>\n\n\n\n

FF:FF:FF:FF:FF:FF:FF:FE:YY:YY:YY:YY:YY:YY:XX:XX<\/pre>\n\n\n\n
where YY is the MAC address of the device and XX is something the designer can use the way he\/she likes. Read more about this here<\/a> if you are interested.<\/p>\n\n\n\n
After the filter we now only get an event when the Woken up event is sent. <\/p>\n\n\n\n
Email<\/h5>\n\n\n\n
The email setup is using the standard email tool (node-red-node-email<\/a>). Nothing special with this setup. Just plain old mail delivery. <\/p>\n\n\n\n
Before the email node I specify the mail content<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
I think it is pretty clear from the above picture where all fields go in the email. <\/p>\n\n\n\n
Nothing more to it. An email is now sent when physical post arrives.<\/p>\n\n\n\n
Telegram<\/h5>\n\n\n\n
Telegram<\/a> is a perfect (and free) way to deliver\/receive messages. There are apps and tools available for every platform. One just set up a bot (channel) and then subscribe to it on devices that should get the message.  Download telegram first for your platform(s) (computer, tablet or phone).<\/p>\n\n\n\n
Microsoft have a good walk through here<\/a> on how to create a new bot. No need for me to repeat the steps. <\/p>\n\n\n\n
In node-red I use the node-red-contrib-telegrambot<\/a> node (telegram sender<\/strong> in this case). There are many other packages around but this one worked fine so I stick to it. My setup is like this<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
and<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
The token is the token you get from the setup.  It looks something like this<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
The message needs to be defined here also and that is done in the stage before the telegram sender<\/strong> node. This is how I set it up<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Now if you have installed Telegram on your phone\/computer\/tablet or whatever you will never miss the post delivery again and if you are fast enough you may even have time to wave to the postman\/postgirl.<\/p>\n\n\n\n
Here is the node-red code for this setup<\/p>\n\n\n
