Adding a Shelly to bathroom light

[jnix2]

Hi

I'd like to be able to control my bathroom light via wifi (for automating some things for when we're away) as well as it working as normal via the current pull switch.

The same pull cord does control a fan too - although I have that switched off at the isolator switch because we don't need it running.

From what I can tell, that's exactly what a Shelly relay will do. Pic of the wiring is attached. It looks like I'd need a Shelly 1L (no neutral) - is that correct? I don't need power monitoring.

I'm a reasonably competent DIY-er - is this something I could do myself? Please can someone give me a simple guide to how it should be wired?

You need fan to work to avoid condensation and mould . Why would you want bathroom light on when not there?

The wiring diagrams are here: https://shelly.cloud/knowledge-base/devices/shelly-1l/

While it claims to work with no neutral, it is very likely to cause problems.
Far better to install it in the ceiling next to the light or fan where the neutral is available.

We have a separate shower room - where we do use the fan.
The bathroom doesn't get steamy - when occasionally we use the bath we open the window.

We like to leave some lights on when we are away - as a deterrent. It would be good to use the bathroom light for this, triggered by sunset/sunrise etc

Thanks. I'll take a look.

Bathroom light would indicate no one’s home as they usually only get used for short periods, easy to just use a WiFi socket on a lamp somewhere .

Found it easier to drop neutrals to all my switches to use shelly’s
