+   You need a remote server somewhere on the internet (tested with Hetzner Cloud). No Raspberry or other local hardware required. Data is pulled from SENEC via cloud access by using your credentials from mein-senec.de

 ## B: You have a PV system, but no SENEC?
 
 If you do not have a SENEC battery system, you may still be able to use **SOLECTRUS**. There is a brand new [MQQT-collector](https://github.com/solectrus/mqtt-collector), so SOLECTRUS can be used with any PV device that supports MQTT. Please note that the MQTT-collector is in an experimental stage and I would appreciate your feedback.

+# Remote installation with cloud access to SENEC
+
+This guides demonstrates how to set up a SOLECTRUS instance on a remote server at Hetzner with cloud access to SENEC.
+**Please note: Cloud access is new and not yet tested by many users.**
+
+### a) Order your server at Hetzner
+
+Sign up on Hetzner:
+https://hetzner.cloud/?ref=NggV8HU9FqCz
+(referral link, will give you a discount of €20 - and me too)
+
+Order your server:
+
+- Go to https://console.hetzner.cloud/projects
+- Select "New project", name it "SOLECTRUS", open the project
+- Select "Add server"
+- Location: Select a location near you
+- Image: Select "Apps", then "Docker CE"
+- Type: The smallest machine is enough, so select "Arm64" architecture and then "CAX11"
+- SSH-Key: If you already have an SSH key, you can add it here to avoid struggling with SSH password. Otherwise, leave it blank.
+- Order (for €4,51 per month)
+
+### b) First Login
+
+After the server has been created, it receives a public IP address. Write it down, it will be referred later [YOUR-SERVER-IP-ADDRESS].
+
+Login to your server:
+
+```console
+ssh root@[YOUR-SERVER-IP-ADDRESS]
+```
+
+If your are not using SSH keys, you are asked to enter your password. Type in our password you get from Hetzner per email. On first login, you are asked to change your password. Choose a strong password.
+
+Check if `Docker` is installed and running:
+
+```console
+docker --version
+Docker version 25.0.1, build 29cf629
+
+docker compose version
+Docker Compose version v2.24.2
+```
+
+Nice, `Docker` is preinstalled.
+
+### c) Create folders for configuration and Docker volumes:
+
+```console
+mkdir solectrus
+cd solectrus
+mkdir redis postgresql influxdb
+```
+
+### d) Create configuration file
+
+Download the configuration file from the repository;
+
+```console
+curl -L "https://raw.githubusercontent.com/solectrus/hosting/main/guide/external-server-cloud/.env" -o .env
+```
+
+Edit the downloaded file and change values to your needs.
+
+```console
+pico .env
+```
+
+IMPORTANT settings, MUST be changed:
+
+- APP_HOST # Hostname or IP address of your cloud server
+- SENEC_USERNAME # Your SENEC username
+- SENEC_PASSWORD # Your SENEC password
+- SENEC_SYSTEM_ID # Your SENEC system ID (optional, if you have multiple systems)
+
+Not required, but highly recommended:
+
+- ADMIN_PASSWORD
+- INSTALLATION_DATE
+- INFLUX_PASSWORD
+- INFLUX_ADMIN_TOKEN
+- FORECAST_LATITUDE
+- FORECAST_LONGITUDE
+- FORECAST_DECLINATION
+- FORECAST_AZIMUTH
+- FORECAST_KWP
+
+WARNING: Don't forget to change passwords, because otherwise everyone can access your database!
+
+Save file and close the editor: <kbd>Ctrl+S</kbd>, then <kbd>Ctrl+X</kbd>
+
+### e) Download Docker compose file `./docker-compose.yml`
+
+```console
+curl -L "https://raw.githubusercontent.com/solectrus/hosting/main/guide/external-server/docker-compose.yml" -o docker-compose.yml
+```
+
+### f) Start Docker containers
+
+To check if all works fine, we start the containers in the foreground:
+
+```console
+docker compose up
+```
+
+This could take some minutes for the first run, because some images are download. You see some output like this:
+
+```
+✔ Network solectrus_default                 Created
+✔ Container solectrus-db-1                  Created

+app-1                 | Use Ctrl-C to stop
+```
+
+Note:
+
+- Port `3000` (Dashboard UI) is mapped to 80, so you can access it from your browser without specifying the port
+
+### g) Open the app in your browser
+
+Open `http://[YOUR-SERVER-IP-ADDRESS]` in your browser. You should see the dashboard.
+
+### i) Run services in the background
+
+Stop services by pressing <kbd>Ctrl+C</kbd>. Then start again as daemon:
+
+```console
+docker compose up -d
+Starting solectrus_redis_1              ... done
+Starting solectrus_db_1                 ... done
+Starting solectrus_influxdb_1           ... done
+Starting solectrus_forecast-collector_1 ... done
+Starting solectrus_senec-collector_1    ... done
+Starting solectrus_app_1                ... done
+```
+
+To check if this works, reboot the machine:
+
+```console
+reboot
+```
+
+Wait a bit, then login again and check if Docker Compose has auto-started the services.
+
+```console
+ssh root@[YOUR-SERVER-IP-ADDRESS]
+cd solectrus
+docker ps
+
+
+IMAGE                                         STATUS
+ghcr.io/solectrus/solectrus:latest            Up 31 seconds (healthy) ...
+ghcr.io/solectrus/forecast-collector:latest   Up 31 seconds           ...
+ghcr.io/solectrus/senec-collector:latest      Up 31 seconds           ...

+postgres:16-alpine                            Up 31 seconds (healthy) ...
+redis:7-alpine                                Up 31 seconds (healthy) ...
+```
+
+### j) Finish!
+
+You are done with step 1. SOLECTRUS is now installed on your server and can be accessed from your browser.
+
+`http://[YOUR-SERVER-IP-ADDRESS]`
+
+### h) Optional: Import historical data
+
+On [mein-senec.de](https://mein-senec.de) you find download links for your historical data. Download the CSV files and import them into SOLECTRUS. See [CSV-Importer](https://github.com/solectrus/csv-importer) for more information.
+
+### i) Staying up to date
+
+To update your installation to the latest release, run:
+
+```console
+ssh root@[YOUR-SERVER-IP-ADDRESS]
+cd solectrus
+
+docker compose pull
+docker compose up -d
+```
+
+To not have to do this manually every time, the `docker-compose.yml` contains [Watchtower](https://containrrr.dev/watchtower/), which is a free tool to automatically update running Docker containers. Once installed, it will check for new Docker images once every day and updates your containers automatically. And of course, Watchtower also runs in a Docker container.
+
+### c) Finish!
+
+You are done. You should see the measurements from your SENEC device in your SOLECTRUS instance:
+
+`http://[YOUR-SERVER-IP-ADDRESS]`
