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 ๐Ÿ™‚

Now let’s come to my favorite project from the past weeks ๐Ÿ™‚ 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.

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 ๐Ÿ™‚

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 ๐Ÿ™‚
