Shelly 2

frund

Shelly 2 looks like the unit I need to remotely control my central heating when abroad etc.
I can see that 2 relays can be controlled independently by manual switch or [Android phone in my case] eg on manually off remotely or vice versa. Not being the worlds best with electronics but quite capable domestic wiring. Here is my question.
In order to work the relay manually can I use a toggle switch like a ordinary on off or does it have to be a momentary switch [for 240v ?  where would I get one]

I intended to wire boiler with control panel with indicator showing when on or off with Shelly 2 somewhere inside. Relay 2 switching, already working, Honeywell controller for gravity domestic hot.

Any advice welcome.

Having done a bit of reading the momentary switch would appear to be the one. I will toggle live supply 1 boiler 2 thermostat with manual hot water switch. All with indicator lights it will be like Christmas.
