Signal Messenger (Native APIs)

[dotbanana]

Hello,

i would like to request a "Signal Adapter" as alternative to the existing whatsapp and telegram-adapters.
https://signal.org/en/ https://github.com/signalapp

Signal is the only messaging service that uses a fully open source client and also a common cryptographic implementation. Signal, while being long on the market, unfortunately lacks a userbase despite being praised by people like Edward Snowden.
Having the ability to get notifications through signal or even control our smarthomes through a (more) secure interface would be fantastic.

There seems to be a cross-plattform-cli available:
https://github.com/signalapp/libsignal-service-java
https://github.com/AsamK/signal-cli
https://github.com/signal-bot/signal-bot (Python)

Official Signal Documentation:
https://github.com/signalapp/Signal-Server/wiki/API-Protocol

Thanks for your attention and your great work here

Hatte auch schon über eine Realisierung nachgedacht, da es ja sogar etwas als Javascript gibt. https://github.com/signalapp/libsignal-protocol-javascript

I also thought about such an integration (see https://forum.iobroker.net/topic/31675/iobroker-und-signal-messenger/8)

I did not write an ioBroker adapter, yet but I would like to help! I think it is the best to be as close as possible to the official Signal flow, so the Javascript linked to by @Hirsch-DE is the way to go.

So I would like to contribute, how we shall proceed? Is there already something somebody did or do we start from zero?

KR, Christof

I compiled signal-cli https://github.com/AsamK/signal-cli and was successful in registration of my wired telephone. Daemon is running and I can get messages from my phone.

Now the question is, which eco-system is the most stable resp. most up-to-date of the ones mentioned in the first post?

[mericon]

It Seems that Signal-Cli is the best Maintained Eco-System since the Others are a Bit outdated.

I cant Help much but if more informations are needed i can try to do some Research

[JuniperChris929]

+1 for this Idea. Being able to send secure messages via Signal compared to the other "low encrypted" ones like Telegram would be more than awesome :) Thank you, you legends, for working on this!

[tardar]

+1 for this idea - love the idea :)

[DutchmanNL]

Habe mal bissl Research gemacht, dieser Node-red Lob sieht sehr viel versprechend aus und up-to-Date das könnte man in einen Adapter einpflegen bzw. die Logic/structuur übernehmen

(Ich habe leider Zuviel andere Projekte gerade um mir das weiter an zu schauen bzw nen Test auf zu setzen sorry 🙈

Maybe this can help (just found it and it sounds interesting)

mjahn started here something. can someone check? https://github.com/mjahn/ioBroker.signal_cli

[Goeste]

a workable solution can be found here: https://forum.iobroker.net/topic/31675/iobroker-und-signal-messenger However the signup and so on could be put into a nice adapter, right?!

[oe8bck]

Today there is an article in the German magazine "c't" how to access the Signal eco-system via CLI: https://www.heise.de/ratgeber/Signal-Nachrichten-per-Kommandozeile-und-Skript-verschicken-6118353.html This is using signal-cli, which is a JAVA command-line utility written by the Signal Foundation.

The connection to a phone number is described in detail, both ways, a new phone number as well as the connection to an already connected one. And also the interaction with D-BUS is described, examples can also be found in https://github.com/AsamK/signal-cli/wiki.

I think this would be an easy way to go: the CLI toolset has to be set up and connected and then the interaction with ioBroker is done via DBUS.

I think I'll give this a try, when I find time to.

The adapter https://github.com/ioBroker/ioBroker.whatsapp-cmb uses https://www.callmebot.com/blog/free-api-signal-send-messages/ , which (according to my understanding) does support Signal, too. So maybe that adapter could be extended (with adjusted adapter name).

[Zelkin0815]

+1 von mir, das würde endlich den Telegram adapter ablösen :)

[oe8bck]

After some time I ha another search for options of a Signal adapter. Then I found this Node-RED client node: https://flows.nodered.org/node/nodered-contrib-signal-client

I am currently installing it, maybe this is the way to go, esp. as there is a documentation of the registration available.

[cyzuer]

Im using Signal-CLI by AsamK and send Messages via javascript-adapter with the exec-block

[ldittmar81]

I found this here https://github.com/mjahn/ioBroker.signal_cli @mjahn do you need some help?

[derAlff]

I have published a Signal adapter yesterday (21.01.2022). The adapter is working with the CallMeBot-API (https://www.callmebot.com/blog/free-api-signal-send-messages).

Here the link to the adapter: https://www.github.com/necotec/ioBroker.signal-cmb

At the moment you can install the adapter to your ioBroker only via Github.

If you find any issues, please open an issue here: https://www.github.com/necotec/ioBroker.signal-cmb/issues

If you have any idea, problem or you only need informations, then you are welcome in the thread in the ioBroker forum: https://forum.iobroker.net/topic/51645/test-adapter-signal-cmb-signal-messenger

[JuniperChris929]

Awesome! But I will not register with a third-party like "callmebot" when I can directly call the Signal-API. Kind of breaks the "secure messaging" Idea 🙃

[ldittmar81]

Close this issue after https://github.com/ioBroker/ioBroker.repositories/pull/1615 review

[Ilovegym66]

sorry, it's a workaround for a adapter. Why is the API not used? it's a secure break.

[derAlff]

sorry, it's a workaround for a adapter. Why is the API not used? it's a secure break.

Yes, it's a workaround (CallMeBot). But it is easy to use. The adapter is my first adapter for ioBroker. I am reading and testing about the Signal library, but it isn't working.

For that (for me) I've created this, because I don't use Whatsapp or Telegram.

[Apollon77]

I would change title here and leave open also after we accepted the current one ...

[ldittmar81]

Signal Messenger CMB ist on latest... with native API is following

[derAlff]

FYI I'm working on an adapter that's working with the Signal API ;)

[JuniperChris929]

FYI I'm working on an adapter that's working with the Signal API ;)

AWESOME!

[Zelkin0815]

Cmb is a great workaround...... Native API is the final solution! 👍

[BenjaminK87]

Any news on the native API? Would be really helpful.

[mericon]

Hi, it is not fully a native adapter but i am currently working on an adapter that uses the Signal-cli-Rest-API docker to send and receive messages. The first alpha is ready now: https://github.com/mericon/ioBroker.signalclirestapiclient

[JuniperChris929]

Why for Pete's sake would you unnecessarily add Docker to the mix???? 🙈🤷🏻

[derAlff]

Hanging on the process to verify the phone number. It's not working with the Signal libraries :( If anybody is here who can help me... I'm interested ;)

[mericon]

@JuniperChris929 it is only an other option to cmb. But it advantage is that it is cloudless.

@derAlff Where it hangs actually?

I Opened a thread on the Testing forum the it maybe easyer to support: https://forum.iobroker.net/topic/58973/test-adapter-signal-cli-rest-api-client

[derAlff]

I can register a phone number, can do the "I am not a robot verification", I receive a call or SMS with a verification code. But when I use this code, the registration fails. So I can't login.

[mericon]

I tested it a new times and for me it works. For the registration you run the docker with MODE=normal or MODE=native ? Set the correct path in the docker and the directory exist with writing rights?

[derAlff]

Oooooh sorry, you are talking about your project... I'm talking about my project -> Use the official signalapp libraries

[mericon]

:D

[mcm1957]

FYI I'm working on an adapter that's working with the Signal API ;)

@derAlff Could you please provide an update? Do you still work at this adapter? derAlff/ioBroker.signal-messenger seem to be unchanged since a longer period

[derAlff]

Hey @mcm1957 ,

At the moment is this not my first priority, because I'm ill. Sorry for this.

[mcm1957]

Get well soon Gute Besserung

[derAlff]

Thank you very much! Vielen Dank!
