LetвЂ™s put it this way, we used to offer a 12 months warranty for the No-Neutral Wall switch and then scaled back to a 7-day limited warranty. In addition, the No-Neutral Aqara wall switches have had a lousy reliability track record and it is the reason why we have not brought in any more new stock for the No-Neutral. When the charge is sufficient enough the lights could flicker or blink which can be irritating and sometimes freaky if it happens after midnight.

Unfortunately, this also means that the lights could be building up a charge from the small current. Without a neutral wire, the No-Neutral wall switch will always continue to send a small current to your light fixtures so that it can keep itself powered (its wifi receiver and modules) and continue to listen for your instructions from you or the Gateway. So at this point, the no neutral wall switch would be the solution for our homes, right? Unfortunately, the long answer is a big NO!. We usually see a brown wire which is the live wire and a green/yellow wire which is the Earth wire that is connected ot the metal bracket. The neutral wire is typically blue in colour and is often present in heater and aircon switches. But 99.99% of the time this is incorrect. There are some of us to who open up the light switch look at two different coloured wires and think that we have a neutral wire. Technically all our homes do not usually have a neutral wire. The answer is simple and yet not so straightforward.
