Android app doesn't work anymore...
Hi,
I need some help here. My Android phones doesn't work anymore via 4G.
I just noticed this a few days ago (it used to work fine), and after that I updated to the latest stable version of Domoticz (2020.2) and OS Buster.
But without success. Domoticz on itself is working fine when operated locally.
Another thing that has been replaced a few weeks ago, is my (Ziggo) router. I think I set it up correctly..
This is what I did:
In domoticz, Setup>Settings>Remote Shared Port set to port xxxx.
In my router, I forwarded this port xxxx to the internal IP address of my Raspberry, on which Domoticz runs.
I did a port check on xxxx and it is reported as "open"
So, do I forget something?
Any suggestions are welcome!
Thanks
John

Re: Android app doesn't work anymore...
Hi,
@Johndomo
You should leave the port to 6144, unless you are sure that you want to change it.
If you want to access your Domoticz device, you have to forward port 8080 (for http) in the router to port 8080 of your Domoticz device.
If you want to use https, you have to forward port 443 to port 443 of the Domoticz device.
This assumes, that you use the default ports. (8080 and 443). Of course you can also forward port 80 to 8080 of the Domoticz device.
If you are not sure, log-in into your Domoticz device and issue the command:
WARNING: Secure your Domoticz with a hard to guess password.
Regards
@Johndomo
Remote Shared Port is intended to use with Domoticz Master/Slave. So in this case you have two devices, on which Domoticz has been installed and the Slave and Master devices communicate with each other. Particular "hardware" connected to the Slave is reported on the "Master"as well.This is what I did:
In domoticz, Setup>Settings>Remote Shared Port set to port xxxx.
In my router, I forwarded this port xxxx to the internal IP address of my Raspberry, on which Domoticz runs.
I did a port check on xxxx and it is reported as "open"

Re: Android app doesn't work anymore...
Hi FireWizard,
Many thanks for your information. So my assumption about the Remote Shared Port was wrong.
But now I have a new problem. The cat command makes clear that port 443 is set as https variant, but that port is already forwarded to my Synology NAS. So, should I enter another port number in Domoticz.sh and forward that port to the IP of the raspberry?
Thx, John

Re: Android app doesn't work anymore...
May I give you some unsolicited advice.
- Set domoticz to passwordless access from within your local network
- do not forward any port directly to your domoticz
- install PiVPN which runs very very reliable with WireGuard
- portforward pivpn's port 51820 to your RPI
- when you connect to your RPI through PiVPN you will have a secure tunnel and it is as if your inside your network.
- you will have a secure safe connection to domoticz by going to 192.168.1.1:443 or 192.168.1.1:8080 or whatever your settings are.

Re: Android app doesn't work anymore...
Hello John (@Johndomo),
.
No, it is not necessary to change the https port of your Domoticz. You can leave that port to 443.
Suppose you want to use port 8443 as your new port number.
The only thing, you have to do in your router is to forward port 8443 to the IP address of your Domoticz Raspberry Pi, port 443.
All routers can do that.
If you want to have external access to your NAS, you have to call https:// <EXT.IP.ADD.RES> and if you want to access your Domoticz from outside your LAN, you have to call https:// <EXT.IP.ADD.RES>:8443.
Example:
In your case you fill in at "Lokaal" and "IP-adres", your IP address of the Domoticz Raspberry Pi and at "Poortreeks", you fill in 443
At "Extern", "Poortreeks", you fill in 8443. Protocol "Both".
And of course you have also port (External) 443 to your NAS (also port 443).
Regards

Re: Android app doesn't work anymore...
Hi FireWizard,
Many thanks! My challenge has been solved.
Looks like you have the same router...
So, one challenge less, still a few to go.
My end goal is to use my voice via Google Assistant to open the garage door when I drive home in the car.
For this, I am trying to get Controlicz operational. Just started, but it isn't working yet.
But that is another challenge...
John

Re: Android app doesn't work anymore...
Hi HvdW,
Thanks for your advice. This is certaintly something that I want to test later on, I know that is the safer way to go.
Not sure though If I would like to run the VPN server on the Raspberry or on the NAS.
And I am not sure yet how this would work in combination with Google Assistant?
Thx again,
John

Re: Android app doesn't work anymore...
Hi,
@Johndomo
But the principle is for all routers the same.
To be secure you need more. (Presence detection or something else)
I use Nora (for Node Red) for switching Lights, Thermostats, etc and it works fine.
See: https://www.domoticz.com/forum/viewtopi ... hilit=nora
I fully support @HvdW, as I use OpenVPN as well, to access Domoticz and other device on my internal network.
PiVPN can easely live on the same Raspberry Pi as Domoticz. Highly recommended!
Regards
@Johndomo
No, I have a different one, I took the picture from Internet and it was the first Ziggo router.Looks like you have the same router...
But the principle is for all routers the same.
Is that secure? I own a Google Nest Hub (the small one with display) and sometimes this one reacts out of the blue and tells me she cannot help me. If the result is e.g. that a lamp is switched on, ok, not nice, but it does not much harm, but if she opens the garage, if you are not at home????My end goal is to use my voice via Google Assistant to open the garage door when I drive home in the car.

Re: Android app doesn't work anymore...
Maybe not ideally secure, but my garage is not attached to my house, so the risk is limited.
I first tried to use geofencing and combined that with a dummy (activation, safety) switch that I have to set when I start driving home. With one car, this works pretty much ok (>90%), but with the other car it doesn't work at all (< 5%). Not really sure why.
If you use VPN, would you have to connect to that manually, or is your phone always connected to the VPN?
I will have a look at Nora too. See if I understand that...
