 One of the most important backbones in our home is the network infrastructure. We ran CAT7 cables in all rooms, used them for the light switches (see next section) and for the alarm system (see later section). Orange CAT7 cables are either network or light, blue CAT7 cables are alarm system cables.
-Most of the network is run by a TP-Link T-1600G switch which features 48-Ports and PoE+ on every port with a total power capacity of 384W. It's a L2+ switch, so it provides VLAN and some advanced switching stuff. For Internet access, an Ubiquiti EdgeRouter-X powered by OpenWrt is used. All other switches and the WiFi APs are also VLAN capable: That's important, because we defined three VLANs in our home:

-The access points (a TP-Link Archer C7 and a TP-Link EAP221) are also powered by OpenWrt and provide two WiFi networks, one bridge to "Private" and one bridge to "Technik". This way, also the wireless appliances can be added to an "untrusted" network section.

-===== Switching Lights =====
+===== Servers =====
+Yes, I have to write servers in plural. The reason is simple: When I was on holiday, the power supply in my single Home Assistant server died and the whole home automation was down. While this is not a big show-stopper as everything can be controlled without it, it's still annoying. Since then, I've invested in more systems:
+  - 2x Acemagic S1 (Intel N97, 16GiB RAM, 512GiB SSD, Dual Gigabit LAN)
+  - 1x CWWK NAS Mainboard (Intel N150, 32GiB RAM, 1TiB SSD + 2x16TiB HDD, Dual 2.5GBit LAN, Google Coral EdgeTPU)
+The three systems are configured as a fully virtualized cluster, based on Proxmox. The VMs and containers are distributed as follows:
+  - Acemagic 1:
+    - Debian Stable VM: Docker (Home Assistant, ESPHome, Homematic CCU, ZWaveJS2MQTT, MQTT)
+  - Acemagic 2:
+    - Debian Stable VM: FreePBX
+    - Windows 11 VM: Home Service (configuration utilities that do now have Linux equivalents)
+  - CWWK:
+    - Debian Stable LXC: Docker (TVHeadend, Frigate, InfluxDB, Grafana, Lyrion Music Server), Native (NFS, Samba)
+I did not implement realtime failover, but use a replication-based approach: All virtual machines are replicated every 15 minutes to the other hosts. Proxmox takes care of migrating/restarting machines in case of a failed system.
+===== Switching Lights (and other stuff) =====
 Regarding the light switches, I wanted a rather simple solution that can be used stand-alone without any dependency on a central server or infrastructure. For half a year we had a ready-made solution ([[http://denkovi.com/smartden-maxi-io-relay-module-snmp-http-din-rail-box|Denkovi smartDEN IP-Maxi]]), but the system is not very flexible. Plus, since it provides only HTTP and SNMP interfaces, the integration into Home Assistant is also not very tight. Therefore, I went for my own solution based on ESPHome:

   * Input/Relay Module with 8 inputs and 8 outputs
   * Base Module X with ESP32, LAN, 8 relays, 8 digital inputs, OneWire and DMX
+  * Relay Module with 14 relays
 All modules communicate via differential i2c, run along +5V over CAT5 patch cables. Everything is nicely integrated into rail mount modules.

 For the door bells, I went for a HikVision IP-based system that is entirely PoE-powered. The outdoor module contains the base station, the indoor door stations connect to this outdoor station. The only downside is that the modules do not support DHCP, all configuration has to be done statically.
-For better integration, I added a central Asterisk server where all stations connect to. This way, the bell can be forwarded to our smart phones and other VoIP phones.

 The newly installed floor heating can be controlled via wall thermostats as well as over IP: The control modules are Möhlenhoff Alpha 2 IP systems that provide an XML interface.
-As we have a few older radiators, I installed HomeMatic wireless thermostats, wireless wall thermostats and I'm using [[http://www.homegear.eu|Homegear]] as central coordinator. Homegear provides a CCU interface and is therefore easily integrated into Home Assistant.

 ===== Shutters =====
-We have shutters around the house, driven by Elero and Somfy remotes. For the Elero-based shutters, I did a lot of research and finally went for two Mediola v4 gateways. I got them used for a few euros, each gateway can control up to 15 Elero shutters. As integration, I wrote [[http://github.com/andyboeh/mediola2mqtt|mediola2mqtt]], which makes certain Mediola devices available via MQTT, including auto discovery for Home Assistant.
+In the meantime, I replaced all wires with proper 4-conductor wires and all motors with Elero RevioLine motors. They are all driven by my newly developed 14-relais module and ESPHome with the custom [[http://github.com/andyboeh/esphome-elero_wired|esphome-elero_wired]] module.
