Hello.
HA on Docker on Intel. NUC.
It works without problem.
In my case. I didn’t have to set anything up. It has been plugging in, looking at the number of USB generated (/ttyUSB0) and activating SMS integration. Nothing else.
As the modem is connected directly to the NUC and it is connected to a UPS. No problem with me when the light goes out.
Just remember that this gateway only works on 2G (GSM) networks.
Best regards
I’d like to have input boxes where I enter phone number and message that gets sent.
Is it possible and in that case how?
Currently I have to add a notification-configuration for every recipient. I’d like to be a bit more flexible.
Thanks.
Hello.
I use E3372s-153, I can’t recieve SMS - sending works fine 
There is any solution for it?
I use HA on Proxmox VE
Thanks
Hello 
I have some tips how to E3372s-153 works for me.
On Win10 I install special drivers/firmware for Huawei (Przerobienie E3372s-153 HiLink na zwykły modem - Forum bez kabli - Internet mobilny 3G LTE 5G CDMA WIFI - in polish lang).
So, I tried to change E3372 to modem mode only (turn off NCI).
When I config:
AT^SETPORT=“FF;12,10,1,A2”
With “FF;” the E3372 is in only modem mode (I can’t change modem mode with usb_modemswitch command in SSH).
Modem send sms via HA, but not receive. On listening event sms.incoming_sms its just empty all time.
But, when I send:
AT^SETPORT=“A1;12,10,1”
My HA report only USB stick as addional USB disk. It’s not possible to integrate with HA by “sms” addon.
But, when I use usb_modeswitch:
/sbin/usb_modeswitch -X -v 12d1 -p 14fe
12d1 - vendor
14fe - model ID
This data I read from “lsusb” in ssh.
I and restart HA my model ID changed.
My config HA:
sms:
device: /dev/ttyUSB0
After this all it’s work - I can send and receive SMS
This is my way to integrate HA with 3372s-153.
But when I try to turn on only modem mode with
AT^SETPORT=“FF;12,10,1,A2”
AT^SETPORT=“FF;12,10,1”
(or something else with “FF” first)
HA send SMS, but not receive… 
There is a bug…
But, “usb_modemswitch” command I have to use every time, then I restart Proxmox.
How I try to use modemswitch command on config USB, but I can’t do this… someone can help me?
Hello again
After fight, It’s seems to work for me.
I do this:
AT^SETPORT=“A1,A2;12,10,1”
Take aby USB stick (with readable i writeable memory), format, label “CONFIG”, create in this stick folder “udev” and file “10-gsm-model.rules”. In file:
ACTION=="add" \
, ATTRS{idVendor}=="12d1" \
, ATTRS{idProduct}=="14fe" \
, RUN+="/sbin/usb_modeswitch -X -v 12d1 -p 14fe"
After this, put in HA server (HP T610 for me), in Proxmox root panel setting new USB stick to HomeAssistant. Restart Proxmox. In HA panel → Supervisior → Hardware → Import from USB. Restart Proxmox. All works I can send and receive SMS even after reset
Ordered one when I saw your post, just received it today. I can confirm it works very well. Just pop in a SIM card, plug it into a USB port and it exposes a standard AT command set over serial. A couple of AT commands later and I had a first SMS sent to my phone. Signal strength is pretty good with the little antenna that comes with it, although I will probably use an external one with a cable (it’s a standard SMA connector). Awesome value for the price !
I don’t have a free USB port on my Pi anymore, so I’m going to plug it into the NAS and forward HA’s notifications over MQTT instead.
Oh yeah, it needs a 2G network, so it probably won’t work in the US anymore.
Works without issue on hassio / odroid n2+
I have problems setting the udev variables, when I import the file from the USB stick the following error appears in the log:
[15:10:38] INFO: Using udev information from host
[cont-init.d] udev.sh: exited 0.
the stick I labled CONFIG, also I tried using FAT32 and ext4. Both failed.
Also the path /etc/udev/… is not created.
Can se send à sms without defining a phone number inside à notification option?
Make sure the file is under the “udev” folder.
Also make sure the file is saved using LF (Unix style) and not CR/LF (Windows Style). Use and editor like VSCode and make sure the file is saved using Unix style.
Great work from you guys,
I had have a problem with the read automation, as I still have to adjust it a bit to forward SMS to my phone number.
This is how it works for me:
alias: read-sms
trigger:
- platform: event
event_type: sms.incoming_sms
action:
- service: notify.sms_person1
data:
title: SMS received
message: >
SMS from: {{trigger.event.data.phone}}; Text:
{{trigger.event.data.text}}
initial_state: 'on'
mode: single
I also use the cheap SIM800C solution as I couldn’t get the sticks to work.
Hi everyone!
I am trying to configure an E3272 Huawei Modem with Home Assistant on Raspberry Pi 4. I made the device to work only as modem, I can even see a result with
ls -l /dev/*USB*
but I see three results:
/dev/ttyUSB0
/dev/ttyUSB1
/dev/ttyUSB2
Then, I went to integrations, add the SMS integration and as for device, I tried with the 3rd line, error, then 2nd line, still error, then 1st line… still error… I see that the Home Assistant detected a new integration (the sms integration), but does not matter what I write on the device, it is not working…
When I use /dev/ttyUSB2 and /dev/ttyUSB0, I get the error in maximum 4-5 seconds, when I use /dev/ttyUSB1, I get the error in 15-20 seconds, like is tryting to do something… but still it finishes with “Failed to connect”. The device is connected to an USB 2.0 port
Any advices?
Thank you!
reboot the OS could help, I had also met with this issue, and after reboot it became fine.
I did it but still not working… 
Hi
How do you that Graph for the sensor.gsm ?
Standard footer graph for the entities card.
Can you please copy the lovelace configuration , Thanks !!!
An example is on the page I linked to - I’ve recently revamped my dashboard to a more compact format and no longer have the graph displayed.
Hello,
I red the topic, found similar situation as the one I’m facing but didn’t understand the answer.
Home Assistant is running on a Raspberry Pi4 and I try to use a Huawei E3531 Surf Stick.
I log to the Pi4 with ssh then enter
lsusb
Bus 001 Device 007: ID 12d1:1f01 ← The Huawei E3531
Bus 001 Device 006: ID 0658:0200
Bus 001 Device 001: ID 1d6b:0002
Bus 001 Device 004: ID 0bda:5411
Bus 001 Device 003: ID 13fe:4200
Bus 001 Device 002: ID 2109:3431
Bus 002 Device 002: ID 1f75:0621
Bus 002 Device 001: ID 1d6b:0003
Bus 001 Device 005: ID 0403:6015
To see it as a modem, I formatted a USB2 key to FAT32, called it CONFIG create the directory udev and inside this directory the file : 10-gsm-modem.rules where Enter are LF (did it under unix system).
ACTION==“add”
, ATTRS{idVendor}==“12d1”
, ATTRS{idProduct}==“1f01”
, RUN+="/sbin/usb_modeswitch -X -v 12d1 -p 1f01"
I plug the USB2 key and the Huawei E3531 to the Pi4 then reboot it.
Once rebboted, I connect to the Pi4 with ssh then enter
ls -l /dev/USB
crw-rw---- 1 root audio 188, 0 Jun 19 19:20 /dev/ttyUSB0
crw-rw---- 1 root audio 188, 1 Jun 19 19:23 /dev/ttyUSB1
crw-rw---- 1 root audio 188, 2 Jun 19 19:20 /dev/ttyUSB2
crw-rw---- 1 root audio 188, 3 Jun 19 19:23 /dev/ttyUSB3
I added in configuration.yaml these lines :
sms:
device: /dev/ttyUSB2
then rebooted the Home Assistant and now I see a new integration :
If try configure
but it fails. I also try with
/dev/ttyUSB0
/dev/ttyUSB1
/dev/ttyUSB3
it also fails…
Help is welcome
2 more things :
1/ when I enter lsusb the list is a bit different :
Bus 001 Device 008: ID 12d1:155e ←
Bus 001 Device 006: ID 0658:0200
Bus 001 Device 001: ID 1d6b:0002
Bus 001 Device 004: ID 0bda:5411
Bus 001 Device 003: ID 13fe:4200
Bus 001 Device 002: ID 2109:3431
Bus 002 Device 002: ID 1f75:0621
Bus 002 Device 001: ID 1d6b:0003
Bus 001 Device 005: ID 0403:6015
2/ The SIM card I received is protected with a PIN code,
do I need to remove it ?
Update: 2021/06/21
I plug the key on a computer and desactivate the pin code. Then after several reboots, Home assistant accepted the integration on /dev/ttyUSB3.
I tested it to send a message and it works.
depends on your modem and the operator.
in fact, I am using a Huawei E180, it works quite well on 3G (WCDMA) network.
if you have a 4G-modem or 5G, I don’t think there would be any problem.
