Power for (re-used) wall plug

[marceltrapman]

Hi,

I want to re-use two old 433MHz wall plugs (it is an older version of these).

I can take out all that is in there and replace it with my own stuff.

However, the thing obviously (EU) has 230 volts and nothing else.

I am new to this so the question is: what is the (best) way to bring the 230 volts down to what the board (Pro Mini), radio and the relay switch need?

Thanks in advance,

Marcel

I use wall warts like this:
5V 2A USB Port Wall Adapter Charger EU/US Plug

Hmm, I thought of that as well but I did not find any of these at 2A.
Will (have to) look further now that I know they exist because this supplier does not ship to Germany

Thanks!!!

Edit: found this one here

You can also just use transmitter of 433MHz wave and send commands to the wall plug.
I have all the plugs maintained like that.

Hi Andriej,

I won't do that because I have experienced quite some issues with that frequency.
Some of my neighbours use the same frequency and I have had my (kitchen) light go on and off without doing anything (or even being home) too many times with these 2 devices.
That is why I decided to re-use their housing but not the technology...

But, thank you for the suggestion!

Cheers,

Marcel
