Poor wifi reception on 1PM - use 1PM Plus as range extender?

Hi

I've got a 1PM and 1PM Plus installed together in a hot tub outdoors.

The router (Ubiqity Amplifi HD) is 4 metres away through a patio door. Basically line of sight, excluding a sofa!

The 1PM has terrible wifi reception, drops in and out of reception randomly. It's pot luck when I open the Shelly app if the 1PM will be connected.

The 1PM plus has a solid wifi connection.

How can I set up the range extender function of the 1PM Plus to allow the 1PM to have a stable wifi connection?

thanks

Turns out this was pretty easy, nice job Shelly!

I turned on the Range Extender function on the 1PM Plus and the connected the 1PM Wi-Fi to it. Job done.
