Handyman's ESP32 Home Automation Web Server

The ESP32 Handyman home automation web server is up and running. The ESP32 connects to your local WiFi network and then you can connect via your cell phone or your computer or tablet and control eight devices. These are hard wired to an eight relay device which you can see in my previous post. The ESP32 serves up the webpage and switches the eight relays which are in turn wired to the devices you want to control. Virtually all of my lighting is led types. In my shed / shop area I have at least ten led light fixtures all on one circuit. I checked the load with an amp meter and it was less than two amps. The relay switches are rated for 10 amps so no problem there.

Alexa Home Automation R&D

I spent the last couple of weeks getting up to speed on some of the home automation tools that are available off the shelf and home brew versions as well. Many of the components can be used with the Alexa and similar devices. I picked up a couple of the Echo Dot 2nd generation devices and have some of the remote control devices that work with it on the way.  I can see where this thing might be a bit addictive as well as being capable of some pretty sophisticated uses.

I picked up one of these ESP32 boards and it's what got me on the home automation bandwagon. I didn't really know much about it when I bought it but in researching some of its capabilities I learned that it and its predecessor the ESP8266 can be used as a remote device to be controlled by an Alexa. The 32 board is still pretty bleeding edge but has a ton of capability. It has both WiFi and Bluetooth connectivity and a great deal of  information about them is available on the web.

It was a fairly easy undertaking to set up the ESP32 device as a webserver on my home wifi network that can control via a web page... 8 relays that can control lights or other low current devices.


Control by Alexa is not so well supported on the ESP32 but there are many examples using the ESP8266. I have a couple of them on the way.

I also have some Sonoff devices on the way as well that work with the Alexa or with a phone app right off the shelf.

I will be posting more on this undertaking as these parts arrive and get put online.

Stay tuned πŸ˜€

It's Been Busy

Time flies when you are having fun. Close to having the old G Model Allis Chalmers ready to go.These are funky rear engine tractors from the late forties. Designed as a cultivator to plow between the rows of plants... you could look down between your legs and see it at work.




Made a little smoke yesterday with the old Allis Chalmers G model. I had done a valve job on it...
the block looks a bit like a 4 cylinder Briggs and Stratton with the valves in the block. Got the head back on yesterday and tried it with a little starting fluid just to see if it would fire. Put a new gas line on it and it fired right up... purred like a kitten.
