Returned to this project after a long time!

What it is:

It consists of a wireless switch to put in an existing wall switch to control up to two loads. Using two SSR and a ESP8266 to do the wireless communication, it also has two inputs used to connect the buttons of the existing wall switch to work in parallel with the wireless' commands.

We are in the first step of the development of this board. It is already designed and we are waiting the components to arrive in order to produce them. Firstly, we will produce the PCB in DIY model, later we will order some PCBs from a PCB manufacturer.

Feel free to suggest and discuss with me!

Drawback

• Need a Neutral main line to work properly.

Advantages

• No need to change batteries.
• Work with both 220Vac and 110Vac.
• Silent operation due to the SSR components.

Future steps

• Increment thermal protection.
• Designing of a case.
• Hardware Tests.
• Software Development.
• Adding Github repository.
• Adding a proper BOM.
