Barn Tech - September 2021

September was about making the network a bit more robust and a bit easier to use.

Fast internet even during power cuts

Now when there's a power cut our UPS (Uninterruptible Power Supply) will keep our VDSL internet service running.

Achieving this required:

Now we know why it took four Openreach engineers to fix our internet issues earlier this year... the wiring isn't pretty:

With the modem relocated I could tidy up the Study a bit:

We only get 15mins on the UPS with the current load (modem, server, WiFi) but in future I'll work on trelloextending UPS uptime to 30mins, either with more battery capacity or progressively shutting down services.

🏠 HomeAssistant for iOS now finds our server automatically

Configuring 🔗HomeAssistant for iOS is now much easier.

You have to be on the Barn network for this to work, but start the app for the first time and it'll find our HomeAssistant server automatically.

No more having to type in that awkward URL (https://ha.home.whalebarn.com:8443) though you'll still need your username (your first name) and the password (on the gin fridge).

😎 IPv6 LAN

This one's technical, but we now have an IPv6 enabled local network.

🔗What is IPv6?

When your device connects to the Barn network it'll get an IPv6 address as well as the usual IPv4 address.

HomeAssistant and all media players have IPv6 addresses. Cyclops remains IPv4-only for now.

I'm still waiting on Vodafone to enable their IPv6 network IPv6 WAN. Once that happens we'll have quicker response times when accessing other IPv6-enabled sites.
