Product Information

Something like a sonoff or shelly switch relay that can be put in the fixture and wirelessly controlled by a physical switch with different buttons that correspond to different times. The factory recommends that the sensor is not installed near any light source, The light output from the light can affect the sensor. Thus the "smart timer switch" diagram is oddball and that's why you're having trouble visualising "L2 as substitute for neutral".

Assuming you are not using cheap CFL lamps ie Philips Genie or anything from Poundland we cannot foresee any problem. Once you’ve selected one of the preset countdown settings, the indicator light will flash for the last 10 seconds of the chosen time. If you plan to do that, I would use one two-gang box for the contactor and outlet, and another for the heater switch and light switch. EDIT: With your wife's stated preference for a digital timer, Chris O points out that 24V digital timers are available.Energy-saving, the water pump and home appliance will work according to the time you set, and no need some one to look after them. Exterior light switch timers can be used to vary the levels of lighting across a range of outdoor environments. Besides the large on/off button, it has six additional buttons for each of the preset countdown options. MULTI-PURPOSE: Suitable for slow cookers, coffee makers, indoor lights, festive lights and fans, clothes airers. It seems there are a couple ways to do this, but I haven't seen the exact solution I'm looking at so I wanted to check with the community on this.

I wasn't able to figure out how to get it to accept a status inquiry message and set the countdown in a single message (if you can point me to some documentation on creating dashboard nodes I'd really appreciate it), but in those cases there would be a conflict with the payload anyway. Excellent quality】The timer switch shell is made of high-quality plastic material, which makes it environmental-friendly, safe and durable to use.The Lowenergie Countdown Power Saver helps you to save energy, reduce your bills and protect the environment. However, there may be some flickering or continuous lighting if the correct installation procedures aren’t followed. The for shell is made of high-quality PC material, which makes it environmental-friendly, safe and durable to use. I figure it's easiest to just have everything at 240V, so I've speced a 240V contactor with coil volts at 240 as well, to avoid running a separate line just for the switch.
