Send SMS with USB GSM modem when alarm triggered

novamostra · January 23, 2022, 6:17am

Hello,
first of all thanks @Oscar_Calvo for the great plugin! Over the last days I was trying to make my raspberry pi’s Supervised Installation communicate over SMS using the SMS Integration. The problem was that Home Assistant couldn’t talk to the device (ERR_TIMEOUT). The GSM Device I am using is the Geeethech GPRS Shield based on SIM900, connected over Serial. After spending some time reading the Gammu manual, I noticed that there is the ability to manually set the baud rate in the connection string. Replacing in config_flow.py line 24, and in init.py line 42, the Connection string from at to at19200 solved the problem and now I am able to use it!

I wonder if it’s possible in a future update to include a property in the configuration for the connection (let the default be at) as well, to avoid user interaction with the source code.

For anyone else with similar issues, you can read how to connect the Geeetech Shield to Raspberry PI and integrate it with Home Assistant in my blog.

Thanks for the feedback, please file a new issue with the details, this should be fairly easy to fix.

Thanks for the immediate response! I will fill a new issue now!

Hi @Oscar_Calvo, I have a device that doesn’t allowing setting the SMSC (via command or dialer system you linked above). I’ve had luck sending messages using -smscnumber +4474XXXXXXX in command line gammu, is there a way to manually set it?
I’ve tried editing the notify.py line 62 to encoded_message["SMSC"] = {"Number": "+4474XXXXXXX"} but continue to get the ERR_GETTING_SMSC

Put the SIM in a phone and configure it using the phone. Make sure the phone can send and receive messages before using it with home-assistant.

Nevermind, I’ve fixed the issue. If anyone else can’t set a SMSC on their device and are getting the ERR_GETTING_SMSC (this seems common when using a phone as a modem as they perform the SMSC via software not via the sim… especially old Android phones), they can do so manually,

Create a custom_components folder in your HA config (if you don’t have one already) and in that create a sms folder and place the SMS github files in the folder
Edit notify.py line 62 to encoded_message["SMSC"] = {"Number": "+4474XXXXXXX"} adding in your carriers Message Centre number (also called a service centre number)
Edit the manifest.json file adding in "version": "0.0.1", between lines 2 and 3

Restart HA and it should work. Do note that the integration will no longer update automatically.

Another tip if using an android phone, is enable USB debugging in the developer settings. None of the phones I tested worked otherwise.

Works great, thanks @Oscar_Calvo for all your hard work on this!

Hi,
I found the way to create /etc/udev/rules.d/10-gsm-modem.rules and now I have 3 USB new ports:
/dev/ttyUSB1
/dev/ttyUSB2
/dev/ttyUSB3

why 3 ports?

I tried to use them in SMS integration but I receive always problem to connection to device…how I can solve?

I have to insert before SIM card in HUAWEI E3531 key?

Hi, did you have any luck getting this to work? Mine worked fine until about october 2021, since then it has the same problem as yours.

bremby · January 29, 2022, 12:44pm

Not yet, I will try again.
I just re-installed the HAO
I will keep you posted

a20691 · January 31, 2022, 11:25am

@Oscar_Calvo hi. Can you give us some help here? It is a USB device with SIM800C like the one you have in the list of compatible devices. It worked like a charm until a few months ago, it configured by integration and it worked fine. Now through the integration it is not detected, if you manually add it to config.yaml, the notification of a new device appears in HA but it always fails to connect when trying to configure it.
Thanks

@Oscar_Calvo
I bought the SIM800C as linked from the docs.
unfurtunately i get this error when i am trying to add it.

Failed to initialize, error ERR_TIMEOUT
Failed to initialize, error ERR_DEVICEOPENERROR

I have tried adding it by it’s ID, /dev/ttyUSB3 and /dev/gsm-modem as created in my 10.local.rules, but still geting this issue.
If i remove the simcard i get error for no simcard and no operator instead.

Also it is worth mentioning i am on a RPi4-4gb using Home Assistant OS

Edit: After closer inspection, i figured that the SIM800C wasn’t supplied with enough power and powercycled, added a powered USB hub and it works.

diemon24 · February 6, 2022, 1:07pm

Hi, all !

I purchased a SIM800C USB modem and planned to use it to send/receive SMS. But after connecting to Synology’s USB port, I still couldn’t connect the device.
Command lsusb -l in Synology shows the connected device, just like a Docker container does.

Telnet Synology:
LOGIN@HOST:/dev$ lsusb -i

Bus 001 Device 001: ID 1d6b:0002
Bus 002 Device 001: ID 1d6b:0003

When entering the SMS configuration in configuration.yaml, HA throws an error:
Invalid config for [sms]: No device at /dev/ttyUSB1 found for dictionary value @ data[‘sms’][‘device’]. Got ‘/dev/ttyUSB1’. (See /config/configuration.yaml, line 320).

Please tell me how can I connect the device?

P.s. The SIM card is activated. I check with a call from my mobile to SIM800C.
HA ver: Home Assistant 2021.12.10

bremby · February 6, 2022, 7:27pm

I had similar issue
what i did:

check the sim orientation

remove integration
reboot

in case it doesn’t work… one time I re-installed ha from scratch. in this case it worked without any issues

diemon24 · February 6, 2022, 8:16pm

I installed the SIM card correctly. When I call from my mobile device on SIM800C, I get a call.
Now I have found how to connect in Docker container to Synology USB devices.
Path to devices:
sms:
device: /dev/bus/usb

HA automatically prompted me to install GSM SMS intagration, but it also doesn’t see the device when I run the integration. I tried to substitute the device ID, but it does not determine it.

Additionally, I started the HA container in privileged mode and added permissions to access USB devices:
Added a rule: /etc/udev/rules.d/99-serial.rules
Inside the rule: KERNEL==“ttyUSB[0-9]*”,MODE=“0666”
Perhaps this also helped.

But I still can’t connect the modem…

diemon24 · February 6, 2022, 8:58pm

I know’t why I not see GSM modem in configuration wizard SMS integration… I can’t add screenshot

diemon24 · February 13, 2022, 8:32pm

When registering in a GSM network, should the LED on the modem flash? My modem is not making any beeps. For verification, I only have the opportunity to call the modem and get the correct call. When I disconnect the modem from the USB port and make a call from my smartphone - I get “the subscriber is not available”, but when I plug the modem into the USB port I get a beep to call the subscriber.

I did some work and found out that Synology OS 7 does not have USB/COM chip drivers CH340/341.

google search:

Can’t rebuild ch341.c driver in kernel
Get serial devices working on Synology DS216+II DiskStation

I haven’t seen the option to install these drivers yet. But it seems to me that this is the problem.

nanavn · February 19, 2022, 7:45pm

I installed SIMCOM_Ltd (SIMCOM_SIM800) Revision:1308B02SIM800M32_BT

sudo gammu sendsms TEXT -text “Ohhai”
If you want break, press Ctrl+C…
test passed, I received SMS.

I planned to use it to send SMS, but in home assistant I see

Logger: homeassistant.components.sms.notify
Source: components/sms/notify.py:68
Integration: SMS notifications via GSM-modem (documentation, issues)
First occurred: 22:02:54 (3 occurrences)

How I test the sms gateway in HA?

@Oscar_Calvo - wondering if you want to look at this. I switched my sim from a 3G Huawei USB modem to a 4G ZTE USB modem, and I’m getting ERR_GETTING_SMSC when I try to send.

This SIM worked with the integration unmodified in my 3G modem, problem only started when switched to the 4G modem
The correct SMSC is on the SIM, when I do AT+CSCA? I get a response of +CSCA: "+12063130004",145 and that is correct for my carrier (T-Mobile in US)
I am able to send SMS messages in putty using +CMGS
I am able to receive SMS using the integration without any modifications
I am able to send SMS using the integration, but only when I load it as a custom component and hardcode the SMSC as described by @googanhiem in reply 326

So I have it working when loaded as a custom component, but would like to help have it working in the main component which would open up another inexpensive 4G USB device for people to use.

Problem on Pi4 after upgrading to Home Assistant OS 7.5

Hello, I use a Huawei E3531 Surf Stick to send SMS. Every thing was working nicely on My PI4 running core-2022.3.5 this morning until I upgraded to Home Assistant OS 7.5.

After reboot (I did it several times), I have this 3 error messages:

I updated to OS 7.5 today and my sms is still working. It looks like it isn’t seeing your modem, did you go to the system hardware page and see if the modem is still showing there?
