!false, it't funny because it is true
For some months, my garage door opener has started to acting more and more weird. It randomly forgets the calibration for how heavy the door is to open and close, it totally stops responding, or there are random delays from a command is send until it actually starts moving. So as I see it, it … Read more
It has been a while since my last post, but I haven’t really done any new things, and everything has pretty much just worked as it should. What broke, was my very first Sonoff, which is in the most read post (http://tritek.pw/2016/05/22/replacing-the-itead-sonoff-firmware/), and has been put through quite a few experiments and mishaps, one which … Read more
The last few weeks I have been working on different projects for industrial robots, and while working on that I came across some genuine power supplies, and then decided to test the efficiency between the genuine and copy.
To test that I use two mains power meters, and use the average between the two (I don’t have a high end meter for that, so using two different brands and models should in theory be more accurate than using just one), and to load them I will use my Re:Load Pro electronic load.
After getting the lamp to work correctly, I wanted to take it a step further, and put my own code on it. What I can see through the matte cover, this seems to be a bit more difficult. But let’s take a look inside and see if we can’t find them anyways.
In my latest box from ITEAD, I had both a Sonoff 4CH, and one of their led lamps. And in this post I will start by just using the lamp as they intended it to, by controlling it from the eWeLink app. When I first powered it on, it quickly flashed the led’s on and off, … Read more
So far flashing the ESP8266 has been pretty easy, but with the new Smart Home devices from itead,it has become a bit more complicated. The reason for this, is because they have changed from the ESP8266, to the physically smaller ESP8285. The function of the 8285 is the same as the 8266, but it got … Read more
Wiring I am asked a lot about how to connect to the Sonoff switch, so it can be flashed with ESPEasy, so I am going to try to explain just that. First you need a USB to TTL adapter, they are pretty cheap and easy to find on eBay. The one I got can both … Read more
In a previous post, I had a look at the Sonoff in the “Replacing the ITEAD Sonoff firmware” post, and not long after they released a new and even more handy smart socket, again with a relay inside to switch mains voltage, and a little power supply to power the ESP8266 driving it all. Outside … Read more
Today I received my dual relay board from Electrodragon. The device is a fair bit bigger than the ITEAD Sonoff I had some fun with earlier this week, but instead of only one relay switched output, the Electrodragon got two… Or does it? What we got The dual relay board from Electrodragon, is made to … Read more
I want more… Just a few days ago I replaced the firmware on my Sonoff, and immediately after, I wanted more… After looking on their website, I found a version which also had a DHT11 sensor attached, and I then wanted to do something similar, just with a DHT22 for higher resolution (0.1C on a … Read more
