Caddy Server and Home Assistant DNS Validation

One of the really great things about using the Caddy addon for home assistant has been that it provides a more secure system as it provides automatic SSL certificates and a reverse proxy and manages renewing the certificates before expiry. I had always been unhappy however that since LetsEncrypt dropped support for https certificate validation that it required port 80 to be opened and forwarded on the router in order to renew certificates. This isn’t a huge risk as long as you are using a properly configured firewall. Even most consumer level routers include a SPI (stateful-packet-inspection) firewall and will

How to use a Sonoff Switch with Home Assistant

sonoff s22 switch mqtt firmware

Originally posted 2018-04-21 10:13:41. This tutorial covers the ways to integrate a Sonoff S22 switch into Home Assistant using Sonoff MQTT and flashing Tasmota to replace the supplied Sonoff firmware. I’m going to cover two different methods to get the switch working in Home Assistant. The first just uses the S22 as it comes out-of-the-box. The second requires flashing Tasmota onto the switch and setting up MQTT in Home Assistant. Honestly sometimes it seems MQTT is build up as the greatest thing and it is useful however depending on what you want to achievt, it’s not necessarily the best option.

Automations with Home Assistant

incorrect use of automations in home assistant

Originally posted 2018-03-23 12:28:35. In a previous article, I blogged about Integrating Google Home with Home Assistant.

So what’s wrong with doing it like this? Well these automations will ‘work’ in that if you click on the text and click on trigger, they will turn the light on or off then and there. But how is that better than just clicking the on/off toggle on the

Originally posted 2017-09-22 12:07:35. Home Automation The next logical step with Home Automation and my Google Home is to integrate some LED lights so I started doing some research and came across the Limitless LED lights. As it turns out, I didn’t look far enough and ended up with a few challenges getting everything working. Even posting on and searching forums I found that there was so much assumed knowledge and jargon that it was difficult to get to where I needed to be. So this post chronicles my journey into Home Automation nirvana (for now and for LED Lights

Google Home integration with Home Assistant Update

Originally posted 2017-11-27 15:06:32. Further to my earlier articles in this series about integrating Google Home with Home Assistant I have made a few changes to my configuration. You might remember that I used the all-in-one setup of Home Assistant for Raspberry Pi. There are (were) 3 different ways of setting up Home Assistant on a Raspberry Pi – the all-in-one method as it turns out was probably the original way and wouldn’t you know it, the month after I set it all up it was ‘depreciated’ and no longer supported for new installations although existing installations can continue to
