I wanted a way to be able to easily monitor my 6 3D printers. I thought about mounting a monitor, and just displaying a webpage, but I figured this would give me a much cleaner look on my wall. From the animation above, you can see that one printer is completely off(bottom left), one printer just completed a print, and the bed is about 3/4 of the way to fully cooled(top right), one printer is paused, likely due to filament running out(top left), and the other 3 are currently printing.
I wasn’t planning on writing a post on this, but after I spent 4 hours wrapping my head around this and getting it working, I’m hoping this information might be able to help someone else. A while ago, I purchased this TP-Link 3-Way Smart Switch 2-Pack. I purchased them because the TP-Link stuff seems to be reliable, inexpensive, and it works with HomeAssistant. As an added bonus, you CAN use the smart switch on only one side of the circuit, and keep a dumb switch on the other side. You can turn the light on from either end, and the TP-Link will always show the correct status of the light. This allows you to make your 3-way switches smart for a good price since it always comes with a pair of 3-way switches. I wanted to be able to have the light turn on automatically using the Wyze Sense door sensor and a routine via Alexa.
So I had some old LED strips that were hooked up around the window frame in my kid's room which were not doing anything because the old WiFi controller I had on it was just so flaky and it connected via the cloud to, I'm assuming, China. I revisited getting it working, and it turned out that it was using an ESP12 chip. So I figured I should get that going with ESPHome (Check out my previous article about ESPHome) to give me total local control with Home Assistant.
As I talked about in my last post about the FilaWeigher, I wanted to add MQTT and temperature/humidity(Using the BME280) to that project. Well, I've done that. Refer to the previous post for more details. But now for this one, I'm just going to focus on the updated code and schematics, and the Home Assistant integration via MQTT. I'm going to leave the old post up for the people that don't want MQTT or the BME280 sensor. This version also has JSON output of all the sensors which allows for OctoPrint integration(I actually just finished up that plugin and I'm going to be posting that up soon).
I created this project so I can know exactly how much filament is left on a spool for my 3D printer, an Ender 5 I wrote about previously. However, it can very well be used to weigh anything else. I put a few settings that are specific to the filament, but they don't have to be used.
Recently, Amazon was selling the refurbished Fire 7 tablet for less than $40. The new one runs for juts $10 more. So I figured I would order it and see if it would be an option. After spending an hour with it, I felt confident that I can make it work. I’ve been running it for a couple weeks at the time of writing, and it’s been awesome.
I wrote about the Nelly WiFi Doorbell a little over a year ago. At first, I was pretty happy with it. But after a while, it needed to be reset a couple time and it would need a reboot every couple of weeks. It was just a pain to look after it. It’s probably still one of the best options if you require local recording. In my case, I would love to have local recording, but not with this much hassle. I suspect that there’s a chance that the issues may have been the fact that the transformer was 10VA, and that it may have need a little more juice. But I couldn’t find any details as to what it required. I didn’t feel like experimenting with it, so I decided to go with the Ring Pro.
So as someone that has a blog that mainly has posts that either relate to the ESP8266 or Home Assistant, I feel like I should have been using ESPHome a long time ago
Ever since Ring released their video doorbell a few years ago, I've been waiting for a WiFi video doorbell that didn't rely on the cloud (and a monthly fee), was powered by hard wire, and still looked decent. I've only had it for a few days, but I think that the Nelly Security doorbell accomplishes this. Unfortunately, it looks like the Nelly version is out of stock at the time of writing, but this doorbell has been rebranded by a bunch of other companies, one of which is Nelly.
