Pool pump control and balcony lights

Here’s my relative new balcony control, of course “powered by pimatic”

I use a wemos D1 mini ESP8266 based chip with the great ESPimatic sketch again.
The control box is able to switch on the upper light, the house number plate (see below), the 230V power outlet below the box and the swimmimg pool pump with a relay each. Furthermore there is a DHT22 connected and a LED matrix for visualizing the actual outside temperature. Next step is to connect a rain sensor to the analoge input of the wemos.
I used almost all GPIO’s of the chip, so I used all of it’s potentials.

Below you can see the final design and the wire chaos inside the box. There are 4 phase indicators showing the switch status of the relays on the upper left, to the right you can see the LED matrix, below the matrix is theDIN rail case of the wemos that i just plugged onto a breadboard glued to the case and on the right side you can see the RCD.
Inside the case you can see the 12V psu between the RCD and the wemos, on the right side you can see the power adapter and wire board i created (see below)

Here you can see the left and right side of the case. On my power adapter and wire board I soldered a simple USB plug to have a simple 5V output, just in case to charge a phone or something like that. The other side shows the DHT22 and an on/off switch for the wemos, just in case I need to reset it.

A peek on the ESPimatic control panel

For whom it may concern, my power adapter board from below …

and from the upper side. The long pinheaders from top to bottom are 12V, 5V, 3v3 and to the outer right GND.
The small pinheaders are GPIO connectors, here i connected the wemos’ GPIO with the sensor wires, so it was a little easier to install one after another. On the top in the middle you see the USB jack that is lead out to the side (see pic above), besides there is the 12V power connector, then the 12/5V converter and the AMS1117 board for 3v3 conversion. Relativeley simple but very effective if you ask me πŸ™‚

Now let’s come to my favorite project from the past weeks πŸ™‚ The LED lighted house number plate !

The final version has plexiglas around on all sides since the LED stripe lit very bright through the gap.

2016-05-20 19.25.18

It’s build relativeley simple with plastic brackets / edge coverage from the hardware store, 4 distance bolts (bought on aliexpress), 2 small 12V white colour LED strips cut from a 5meter wheel and a plexiglas plate. Of course you need a sticker with your house number (feel free to ask me for any assistance πŸ™‚

The small LED strips have been glued to the sides, you can see the drill holes in the plate

Here you can see the grey connection cable for both strips from the backside

Maybe I was able to inspire you a bit πŸ™‚

CAUTION! This USB charger can get extremely dangerous

Today my daughter wanted to unplug the below usb charger and it broke apart without any reason!
It would not matter if it just broke apart, but the following situation appeared :

The serious thing is the following – have a look at the picture and judge from what you see …

2016-06-21 15.18.09

As you see, the metal pins with high voltage on it (230V in Europe …) are uncovered and the plug itself sticks to the power outlet!! Usually the pcb is sitting on these pins and takes over the power from them to convert to USB friendly 5V. But as the pcb is not soldered, it is sitting very slacky on the pins and will be jammed in the housing when falling apart …

So be careful and consider to remove these devices if you are plugging them frequently.

pimatic v0.9 has been released !

09 beta-2

Finally we’ve made it πŸ™‚
pimatic v0.9 has been succesfully released!
You can learn more here at the pimatic forum.

The next days will be very exciting. Hoping that our users won’t have big trouble when updating.
Many issues and bugs have been eliminated prior to the release, but you never know. It’s still software ^^

Well, we’re ready for supporting youΒ  πŸ™‚

Now enjoy pimatic v0.9 !

I’ve got the ice, who has the drinks ?

The tempests here in Germany are a real pain for many people!
Fortunately I’ve been untroubled yet. But today we’ve had a hailstorm.

Well, this was of no danger, but it came absolute suddenly without any warning.
There are considerations for a DWD weather-warning plugin (for German users).

Also my thoughts about the rain sensor came up again. My roof window has been opened and closed it quickly since I remembered it. What if I do not remember next time … pimatic needs to remember me then πŸ™‚
