PCB for ESP Sparsnas Gateway

In the early days of mankind it was possible to tap into the signals from IKEA's sparsnär energy meter and send them to Home-Assistant using a simple docker image from Tubalainen

But then the age of hassbian passed and mankind ventured onwards to hassos and thus dockers was no longer a viable option (sad face emoji)

But the dark ages lasted only a moment since the enlightened bphermansson created his code for the ESP_Sparsnas_gateway, a slightly magical thingymajig that instead of using a USB-Dongle use a ESP8266 and a reciever to send the measured values by mqtt do your chosen destination... just like magic!

So why do I need a PCB?

Well you don't need a pcb... but then again there are a lot of things that we don't need but the geeky heart want its fiddly little thingies to show off. If you don't want a PCB here's bphermansson's scheme for connecting all the cables! schematic Right... so now that we've concluded that you don't need a PCB but rather that you really want one to make it easier...

Ok Ok... I'm listening, go on!

Just order the PCB's from any online shop of your choosing. Personally I prefer Seeed studio and you can even find the uploaded files by clicking here so just click, click, click and get your own PCB! You need a few moore parts to tough:

Assembly

Ok, time to get the party started... this is how the PCB looks clean pcb

Now add all the components and it should look something like this: clean pcb

And then just plug in the ESP and the radiocard, plug it into your computer and flash the firmware according to the instructions. clean pcb

Now just flash the firmware according to bphermansson's instructions and you're all set!
