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.
Not yet, I will try again.
I just re-installed the HAO
I will keep you posted
@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.
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.
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
|__usb1 1d6b:0002:0404 09 2.00 480MBit/s 0mA 1IF (Linux 4.4.180+ xhci-hcd xHCI Host Controller 0000:00:15.0) hub

** 1-1:1.0 (IF) ff:01:02 3EPs ()**
Container in Docker:

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
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
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… 
I know’t why I not see GSM modem in configuration wizard SMS integration… I can’t add screenshot 
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:
I haven’t seen the option to install these drivers yet. But it seems to me that this is the problem.
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.
AT+CSCA? I get a response of +CSCA: "+12063130004",145 and that is correct for my carrier (T-Mobile in US)+CMGS
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?
Can you follow these steps?
Hi @novamostra , I am working on getting support for custom baud speed in the configuration settings for SMS.
To use this, you will need to remove the current SMS and add it again.
Support custom baud speed by ocalvo · Pull Request #68320 · home-assistant/core (github.com)
Thank you Oscar,
By removing, Rebooting end adding the integration, I recovered the SMS integration and SMS send/recv is OK
The modem changed from /dev/ttyUSB3 to /dev/ttyUSB4 (The cause is maybe coming from in January, I added a Zigbee USB key),
Hi all,
Thanks @Oscar_Calvo for your great works and advises.
Following this topic I get my SIM800C working with my home assistant OS.
If this can help here is the sum up of what is working for me.
My home assistant version is :
Core 2022.6.0
Supervisor 2022.05.3
OS 8.1
1/ The module I bought (I have no commercial link or any discount by giving this link…) is
2/ getting the device id using the command
ls -l /dev/serial/by-id
3/ writting the folowing config in the configuration.yaml
sms:
device: /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0
notify:
- platform: sms
name: sms_person1
recipient: "+33XXXX"
4/ integrate the GSM-modem (was automaticly discovered for me)
On Node Red, got send sms and received working with the folowing config.
6/ to receive sms
module in node red : "event all"
Server : home assistant
event type : sms.incoming_sms
7/ to send sms
module in node red : "call service"
Server : my home assistant server
domain : notify
service : sms_person1
in detail below the data expression
{
"message":"Hello I am your house and I received your message :' " &
payload.event.text & "' le " & payload.event.date & " from number " &
payload.event.phone
}
The Full flow I use to test the connexion that re-send sms with data previously received by sms (using the config descrbie upper)
But I Stil have an issue. I am not able to update the phone number from node red.
I tried to change the recipient in configuration.yaml to a variable and update it in a node red script , but it is not working.
Does any one have an idea please ?
Thanks,
Best regards
Other information,
I tryed to read the source code, and it seems that the number can comes from the config (like i did)
and can comes from another place like it is mention in the notify.py
if discovery_info is None:
number = config[CONF_RECIPIENT]
else:
number = discovery_info[CONF_RECIPIENT]
does any one now where the discovery_info array comes from
or what is the procedure if I would to custom the code to do some tests on my own?
Thanks
Not the response you’re expecting, but doing it in yaml might be easier (there’s already a post above indicating how to do it)
Anyway, can you try to remove country code from the notification configuration or use 00 instead of + ? I tried two SIM cards from different operators and one of them required country code, whilst the other didn’t.
