My core51822 module has caused me a bit of headache. The headers are 2.00mm pitch rather than the typical 1″ (2.54mm) pitch. This makes it incompatible with regular 1″ pitch breadboards. Being double row makes it worse.
Category: Side Projects
Finally – off the breadboard and into a working environment. It’s currently working for 433mhz sensors, I will possibly be adding more frequencies later. For now I will continue refining the code to release it on github.
A few issues. I accidentally flipped the polarities on the siren. I will eventually implement a 12v regulator to up the voltage for the siren for the full 120db power.
My cat set off one of the motion sensors at 6AM, activating the siren. I need to adjust the sensitivity or get pet-friendly motion sensors.
I will be using two Custom firmware routers to get full house coverage on a very old house with thick lead filled walls. The entire project took 6 hours due to some unexpected issues we faced. You can flash any device below as well to Merlin custom firmware but its entirely optional. This will work with the stock firmware.
I decided due to the lack of community support I am not going to make a Zigbee 433mhz chip instead I will continue my efforts with the WiFi esp8266. Now that I have the 433mhz working with the esp8266 I will be performing some distance testing with a few receivers I purchased and different antennas I have.
I hate “exit intent” popups. The kind that automatically open when your mouse leaves the page begging “please don’t go!”. They’re annoying. They’re irrelevant (I’m following instructions, not closing). They interrupt the content I’m trying to read. So I made a short Userscript to globally block them.
Very few people know that you can save yourself some money by buying a T-mobile router on Amazon. Downside is having to flash it to have the latest firmware free of vulnerabilities. In this guide I will show you how to flash a TM-AC1900 to a RT-AC68U then into merlin custom firmware. I have tested it myself and can confirm that it works.
I wanted to talk about my smart home setup from the ground up. I have many articles describing my setup in pieces but not everyone gets an entire overview of everything I have setup here. I don’t have a mansion or anything fancy like built in sprinkler/irrigation, so this will be more catered to your average city home.
Google Home and/or Mini manage my random routines that aren’t part of a automation rule. Going to the basement to do laundry, or going to sleep at random times. I can just send a command and google home will handle it. Link your SmartThings account and Google Home together for best results. Give all your devices aliases to make it easier to command via Google. I want one located in every central room of the house, Kitchen, Living room, Master Bedroom.
What controls my entire setup and why I chose this hub vs others. My only hub is a Samsung SmartThings hub. This manages just about everything in my home minus the security cameras. I did heavy research on many hubs including Wink, IOT (hub-less), and Phillips hue. Why SmartThings?
For Christmas my mother got a full smart home kit. Samsung SmartThings, sengled bulbs, google home. After pluging everything in the hub was having issues. Finding all bulbs in dome covers. I removed the glass from the dome cover and tried again with no luck. Afterwards I removed the bulb from the socket and put it in a lamp. Detected and added to smartthings fine in the lamp. Readded it to the dome cover and it works now!! Seems all I had to do is add it to the network beforehand so that it joined the zigbee mesh network. Has anyome faced similar issues?
How to get a cheap smart home that actually works. Vision Micro switches lets you use the old fashion switch and also continue to use your old bulbs. Instead of paying $10-30 per smart bulb, you pay around $25 for a single or $30 for a 2 relay switch. 2 relay switches help you save a ton more money, you can use one for 2 gang boxes saving you 2x more money ($15/switch). If you think about it, most ceiling lights have 2-3 bulbs, Why buy so many bulbs when you can buy a single switch.
