I installed two Z-wave switches into my house that i wanted to be synchronized, turn on one light switch, have the other turn on too, and vice versa. I first created a home assistant automation that worked using Z-Wave JS to MQTT, this worked but had a lag of a few seconds. I was hoping to find a way to have less latency to make everything work, so in comes Z-Wave Group Associations.Continue reading “Using Z-Wave Groups vs Home Assistant Automations”
Recently I ran into an error when trying to update Joplin (hooked up to WebDAV on NextCloud).
Last error: FetchError: request to https://nextcloud.rapternet.us/remote.php/dav/files/sbachhub/Documents/Joplin/info.json failed, reason: certificate has expired
I checked the SSL cert with FireFox and everything looked good there. Finally I decided to try updating the application, on a wild attempt to fix it in a simple way, and… it worked. It might have just needed a reboot, but the update worked in this case.
The home assistant API can be used to build external tools to manipulate information in home assistant and control elements in it. This can be useful for triggering automations with custom code. It can even be triggered using curl on linux, allowing for simple scripts executing home assistant actions.Continue reading “Enabling the Home Assistant API”
I have a number of windows with Christmas lights in them. I would like to use smart plugs and home assistant to automate them turning on and off during the winter season since I’m pretty lazy when it comes to decorating. This should be pretty straight forward to do once we have the current month sensor setup in home assistant to use as a condition.Continue reading “Home Assistant Automated Christmas Lights”
I’ve already setup some fairy lights on the stairs which come on just before sundown and stay on until bedtime, but I started wondering, can I use them as night lights on the stairs for when I don’t want to turn on the main overheads, and can I do that all with motion sensors. For this project, I’d like to take my lights from here and add motion sensors so they turn on for some time period after being triggered and act as automated stairway night lights.Continue reading “Motion Sensing Lights with Home Assistant”
After putting together the EspDeck 9 key pad, and talking to the wife of other places we could make things better, the bedroom fan and lights came up. I mentioned that we could use smart switches for them and make a small 2 key control for our night stands, which she was super excited about, and then I showed her the NovelKeys big switches and it was sold, we were going to have some hilarious macro pads to control our bedroom lights.Continue reading “Novelkeys Novelty Big Switch Macro Pad”
I have a light in my pantry that isn’t super obvious when its on if the door is closed, and I may leave the light on from time to time by accident. The light switch is also partially buried in things hanging from the wall, so why not automate it to make things a bit easier, that is what smart homes are for. My idea is to use a smart door sensor and light switch to automate it and keep things from being left on.
- Turn on the pantry lights while the door is open
- Close the pantry lights when the door is closed
- Allow lights to be turned on with the door closed
I have a laser cutter in my office that I use from time to time. I close the door when its running because you need safety glasses on while its running, but since I use my office for other things, the door closed doesn’t necessarily mean safety glasses are needed. To make this simpler, I decided to try and make some automations to notify when the laser is running. I want to use a WLED strip around the door and light it different colors based on laser operating status (and other statuses in the future).
- Set the WLED strip to red when the laser starts cutting
- Set the WLED strip to the previous settings (or turn it off) when the laser stops cutting
I was running upgrades one day and noticed in Proxmox that there was an error about being on an unsupported version. I hadn’t upgraded major versions since I setup the system, so now was the time to upgrade.Continue reading “Upgrading Proxmox Debian from 6.4 to 7”
After picking up some relegendable keycaps for my EspDeck, I needed to start creating some icons to print it and use in them. I’m not the most proficient with image editing tools, so here’s what I did to get some made.Continue reading “Creating Icons for Relegendable Keycaps”
