I’ve been somewhat busy lately and it’s been a long time since my last post. I have a few projects on the go but not much time to sit down and write about them… Let’s see if this one goes through…
I’ve been lately looking for a reliable UPS system for Raspberry Pi 3. I moved my home server to a RPi a few months ago and even thou its behind an ACS UPS a couple of other projects involving RPis required mobility (one of them) and unassisted power backup (the other). So I started browsing several marketplaces looking for a solution.
In my last post I tried to explain how to access your IoT devices at home from the Internet in a secure way using a reverse proxy. Truth is that I had it running since maybe 6 months ago without giving it too much use until recently. Reason? My Nexus 5 had been having serious problems (battery not charging, screen broken, earpiece not working,…) and I decided to replace it with a new mobile phone and the new one has Google Assistant built in.
So one of the first things I have tried is to make Google Assistant toggle my smart switches flashed with ESPurna. Nad as it turns out it’s not hard to do but -at the moment- you have to relay on a cloud service like IFTTT (IF This Then That). This is a key difference with Amazon Alexa services you have to be aware. It has some benefits but also some drawbacks.
When you are hacking with IoT devices at home you get to face the challenge of accessing remotely to them, that is from outside your home network. I’m not saying your home network is a safe place, beware. But that thing outside, you know, “the Internet”, it’s so scary… Unfortunately, most IoT devices are just not ready for the jungle. Neither the commercial ones, nor the hacked ones you might have. I wouldn’t dare to open a port in my router to anything inside unless it’s encrypted. So what should we do?
