So, what is the first thing you need after you buy a house: Of course, an internet connection 😀 Good thing Estonia is the country where internet is considered a human right, so 10 minutes after I stopped by at the Telia office, I walked out with a 4G card for 16 euro per month. According to planning a glass fiber connection should be available by the end of February 🙂
At home I installed it to the 4G USB modem and connected it to a spare FritzBox! modem. The next morning I installed it at the house in combination with a Raspberry Pi with HomeAssistant and a security camera. The temperature/humidity sensor registered 1 degree Celsius and 86% humidity. No wonder it was uncomfortable to sit there installing stuff.
The openings in the firewall gave some trouble. Later on I found out this is caused by the extra network the 4G modem sets up. And with this firmware I cannot setup a DMZ connection to the FritzBox!, so this needs some more tweaking.
