The alerts coming from my SMS gateway differs only in the text message, so it is important to define clear message and select the alarm alarming not too much nor too little Node-RED Futura SMS alarm Of course I would like to have a different kind of alarm for a different type of event, unfortunately, considering the available app, this can be done only if the sender number varies. I started the stopwatch, pressed the doorbell and … Then «function» node: Name: DOORBELL RINGINGĪnd finally the last, «file» node: Filename: /var/spool/gammu/outbox/OUT7XXX1XXX1.txtĪfter deploying, the whole flow looks like thisĪnd here is the screen video of my phone. Topic: node/carpinus/push-button/-/event-count Starting with «mqtt in» node: Server: localhost:1883
I take for granted that we have the setup described in the post Building Sensor Network: with BigClown which includes Node-RED running as a pm2 process. Node-RED Doorbell SMS alarmĪfter building the smart Doorbell in the post IoT Doorbell: with BigClown, it is the time to see it in action. Adding filters on text keywords, it would be perfect. It is nice and functional, but it can only define alarm based on the SMS sender number. In reality, I have found just one app which was usable for the purpose but still, with limitations. Then making alarm definition using filters based on a combination of senders, text and more, and finally defining the properties of alarm, sound, light, vibration effects. I would expect many of them, offering to select the communication channel, like SMS, email, Twitter, Telegram and so on.

Surprisingly, I didn’t find a perfect app for setting up smart alarms on android device. Having the cheapest tariff, the total monthly costs for one SIM is around 0.15 Eur.

To send SMS alerts I use one of the Czech mobile virtual operators which offer free calls and SMS within its network. sudo nano /etc/gammu-smsdrcįinally, we are here. I put commtimeout = 1 and sendtimeout = 20. You can also change some setting in the config. Then making sure the service is running service -status-all | grep gammuĪnd to make sure it works with any pm2 process running under my user sudo chown -R luba:luba /var/spool/gammu/outboxįinally the SMS test, file name is «OUT» + phone number echo "Hello Earth, Mars calling" > /var/spool/gammu/outbox/OUT7XXX1XXX1.txtĪnd success again. Then it is very easy to integrate with Node-RED or anything else. The idea is that new SMS is created as a text file in SMS outbox directory. It was a success, so I started another installation and setup to create simple file based interface for sending SMS. Then tested sending an SMS to number 7XXX1XXX1 echo "test" | sudo gammu sendsms TEXT 7XXX1XXX1 Within the configuration, I only changed the port according to the screen above (The first one from the three listed).

sudo apt-get install gammuĪnd make some configuration: sudo gammu-config I tested the setup for both Raspberry-pi and my tablet with Lubuntu getting the same output. This particular dongle Huawei E3531 is from Czech market and it was manufactured for O2 operator. This setup worked for me, it is a compilation of many sources. Then reboot with the connected dongle and check whether it is mounted.
Then some configuration: sudo nano /etc/udev/rules.d/40-usb_modeswitch_lesĪTTRS="15ca", RUN+="usb_modeswitch '%b:%k'"Īnd another configuration: sudo nano /etc/usb_modeswitch.d/12d1\:15caĪdding this content: #Huawei E3131 (Variant) I bought a cheap 3g USB dongle Huawei E3531 and inspired by article Sending SMS on a Raspberry Pi started the installation.įirst this: sudo apt-get install ppp usb-modeswitch usb-modeswitch-data For now, just the first access layer, the MQTT. Having SMS gateway, we can create first practical use cases utilizing the data in access layers. The critical communication channel in the sensor network I build and describe in my blog. Before designing some simple flows in Node-RED, lets’s create functional SMS gateway.
