|
|
|
|
> *This package allows you to install Domoticz quickly and simply on a YunoHost server.
|
|
If you don't have YunoHost, please consult [the guide](https://yunohost.org/#/install) to learn how to install it.*
|
|
|
|
## Overview
|
|
|
|
Domoticz is a Home Automation system design to control various devices and receive input from various sensors.
|
|
For example this system can be used with:
|
|
|
|
* Light switches
|
|
* Door sensors
|
|
* Doorbells
|
|
* Security devices
|
|
* Weather sensors like: UV/Rain/Wind Meters
|
|
* Temperature Sensors
|
|
* Pulse Meters
|
|
* Voltage / AD Meters
|
|
* And more ...
|
|
|
|
|
|
**Shipped version:** Always the last stable one. The last compiled version is retrieved from [this directory](https://releases.domoticz.com/releases/?dir=./release) during install.
|
|
Once installed, **updates from the uptream app are managed from within the app**. Yunohost upgrade script will only upgrade the Yunohost package.
|
|
|
|
The MQTT broker mosquitto is integrated into the package. It requires its own domain or subdomain. It's an optional setting: during install if you set the same domaine as your main app domain, it won't be installed.
|
|
|
|
## Configuration
|
|
|
|
### Broker Mosquitto
|
|
|
|
During installation, a [MQTT](https://en.wikipedia.org/wiki/MQTT) broker, [Mosquitto](https://mosquitto.org/), is installed at the same time as Domoticz. The installed version is the one from the official project repo and not from Debian ones.
|
|
This broker requires a dedicated domain or subdomain to work (ex : mqtt.your.domain.tld) : creating this domain prior installation is a prerequisite
|
|
|
|
#### Adding in domoticz
|
|
|
|
To use mosquitto, you need to customize the communication between domoticz and the broker by following the [domoticz documentation](https://www.domoticz.com/wiki/MQTT#Installing_Mosquitto), part *Add hardware "MQTT Client Gateway"*.
|
|
User and password are automatically generated during installation, you may retrieve them with
|
|
````
|
|
sudo yunohost app setting domoticz mqtt_user
|
|
sudo yunohost app setting domoticz mqtt_pwd
|
|
````
|
|
|
|
#### Publish/Subscribe
|
|
|
|
By default, mosquitto will listen on 2 ports:
|
|
- 1883 on localhost using mqtt protocol
|
|
- 8883 using websocket protocol. Nginx redirect external port 443 to this internal port.
|
|
|
|
Hence, To publish/subscribe on a topic from the outside, you have to use a software supporting websocket protocol (ex : paho python library).
|
|
|
|
#### Mosquitto_pub et mosquitto_sub
|
|
|
|
These 2 tools do not support websocket protocol, only direct mqtt: base settings will not allow communication from an outside device.
|
|
If you're using them directly from your server, this kind of syntax should work:
|
|
````
|
|
mosquitto_pub -u *user* -P *password* -h mqtt.your.domain.tld -p 1883 -t 'domoticz/in' -m '{ "idx" : 1, "nvalue" : 0, "svalue" : "25.0" }'
|
|
````
|
|
In the same way:
|
|
````
|
|
mosquitto_sub -u *user* -P *password* -h mqtt.your.domain.tld -p 1883 -t 'domoticz/out'
|
|
````
|
|
|
|
If you wish to open direct mqtt protocol from an outside device, you'll need to:
|
|
- open port 1883 on Yunohost firewall (**Attention, security risk**)
|
|
- Allows IP addresses in mosquitto configuration for this listener
|
|
- Set the tls setting in mosquitto configuration by giving access to crt.pem and key.pem from your mqtt domain by setting respective certfile et keyfile variables. **This is mandatory to ensure a secure connection.**
|
|
|
|
#### Upgrade from version without mosquitto
|
|
If you have package ynh3 or below, mosquitto is not installed by default.
|
|
If you have chosen to not set a domain during initial installation also.
|
|
So, if you need to activate mosquitto in retrospect, do following actions:
|
|
1. Create a domain or a subdomain (for example : 'mqtt.your.domain.tld')
|
|
2. Connect to your server in command line
|
|
3. Type following command : `yunohost app setting domoticz mqtt_domain -v mqtt.your.domain.tld`
|
|
4. Upgrade domoticz to last package.
|
|
If you're already on the last package version, use the following command : `yunohost app upgrade domoticz --force`
|
|
|
|
## Configuration
|
|
|
|
### Sensors, language and this kind of stuff
|
|
Main configuration of the app take place inside the app itself.
|
|
|
|
### Zwave management
|
|
If you're using zwave devices, install mosquitto along domoticz and give a try to [zwave-JS-UI package](https://github.com/YunoHost-Apps/zwave-js-ui_ynh).
|
|
Once installed, just follow instructions from the [wiki](https://www.domoticz.com/wiki/Zwave-JS-UI)
|
|
|
|
### Access and API
|
|
By default, access for the [JSON API](https://www.domoticz.com/wiki/Domoticz_API/JSON_URL's) is allowed on following path `/yourdomain.tld/api_/domoticzpath`.
|
|
So if you access domoticz via https://mydomainname.tld/domoticz, use the following webpath for the api : `/mydomainname.tld/api_/domoticz/json.htm?yourapicommand`
|
|
|
|
By default, only sensor updates and switch toogle are authorized. To authorized a new command, you have to manually update the nginx config file :
|
|
````
|
|
sudo nano /etc/nginx/conf.d/yourdomain.tld.d/api_domoticz.conf
|
|
````
|
|
Then edit the following block by adding the regex of the command you want to allow:
|
|
````
|
|
#set the list of authorized json command here in regex format
|
|
#you may retrieve the command from https://www.domoticz.com/wiki/Domoticz_API/JSON_URL's
|
|
#By default, sensors updates and toggle switch are authorized
|
|
if ( $args ~* type=command¶m=udevice&idx=[0-9]*&nvalue=[0-9]*&svalue=.*$|type=command¶m=switchlight&idx=[0-9]*&switchcmd=Toggle$) {
|
|
set $api "1";
|
|
}
|
|
````
|
|
For example, to add the json command to retrieve the status of a device (/json.htm?type=devices&rid=IDX),modify the line as this:
|
|
````
|
|
if ( $args ~* type=command¶m=udevice&idx=[0-9]*&nvalue=[0-9]*&svalue=.*$|type=command¶m=switchlight&idx=[0-9]*&switchcmd=Toggle$|type=devices&rid=[0-9]* ) {
|
|
set $api "1";
|
|
}
|
|
````
|
|
|
|
All IPv4 addresses within the local network (192.168.0.0/24) and *all IPv6* addresses are authorized as API.
|
|
As far as I know, there is no way to filter for IPv6 address on local network : You may remove the authorization by removing or commenting this line in `/etc/nginx/conf.d/yourdomain.tld.d/domoticz.conf`:
|
|
````
|
|
allow ::/1;
|
|
````
|
|
This will authorized only IPv4 within local network to access your domoticz API.
|
|
You may add individual IPv6 address in the same way.

**Shipped version:** 2020.2~ynh7

## Disclaimers / important information
|
|
|
|
|
|
## Limitations
|
|
|
|
* No user management nor LDAP integration This function is [not planned to be implemented into the app](https://github.com/domoticz/domoticz/issues/838), hence it's not planned into the package neither.
|
|
* Backup cannot be restored on a different machine type (arm, x86...) as compiled sources are different
|
|
|
|
## Security consideration
|
|
|
|
Although you may activate a login page on the application (either from the *Setup/Settings/System/Website protection* menu or from the *Setup/More Options/Edit Users* menu), it doesn't seems to be very reliable and secure so far (version 2022.2 at the time of writing). Work is ongoing to strengthen the security ([see here](https://www.domoticz.com/wiki/Security)) in future version but is not yet released.
|
|
|
|
### recommandation
|
|
|
|
It seems advisable to not make the app publicly available outside of the yunohost sso (public = yes at install or setting the domoticz permission to 'visitors' in the admin panel). If for any reason you need to, I recommend the following:
|
|
- Activate the website protection/user management (with login page instead of Basic-auth)
|
|
- In *Setup/Settings/System/Local Networks (no username/password)* enter the address of the nginx proxy (should be "::1;127.0.0.1" in any standard Yunohost installation) so that the Fail2ban settings is active (see last lines of [this wiki](https://www.domoticz.com/wiki/WebServer_Proxy)
