D1 switches on its own

My D1 Dimmer Module, controlled by Android app eweLink, switches on its own - apart from the timers set in the app. I already reinstalled and paired the D1 module without success.

Pairing had be difficult, too. My 9th attempt in Quick Pairing mode was successful, but did not solve the problem of randomly switching.

Sorry Lewrobert, I dont think there is a solution without using an RF remote.


There are two entirely separate circuits inside, one for wifi that responds to the app, and one for RF that responds to the remote control. The fault is definitely in the RF side. Without a remote, you wont be able to pair it often enough to overcome the fault in the initialisation. 


Your best bet is to buy one - about $5 from AliExpress, or I will offer to pair to one of my remotes to resolve the problem for free (would cost postage to a UK address for the dimmer,  if thats cheaper).


Out of interest, which toy/remote does your son have? That might help my investigation further. Does it actually pair (i.e. does the dimmer beep if you hold down a button on the remote within 5 seconds of turning the dimmer on) or does it just randomly influence the dimmer?

Sorry to hear that I need to buy RF to solve that issue. 

The device that causes this blizzard activity is a remote for RC car. No-name, unfortunately. 

and can you guide me step by step what shall I do having this RF433 already in hands? 

Step by step (assuming you already have the dimmer connected to the app, and have the latest firmware on the dimmer - currently 3.5.0 - in the app, select the dimmer by clicking on the name line, (assuming you have already been to the settings page and already clicked through the information pages), click on the “...” circle at the top right, choose “settings”, look at the top row (should show 3.5.0), scroll down to bottom row (should show PSF-BLD-GL)) then:


- turn OFF the power to the dimmer

- wait 30 seconds (to ensure the dimmer is FULLY powered down)

- hold the RF remote next to the dimmer - touching is best
- turn ON the power to the dimmer; immediately (within 5 seconds) press and HOLD one of the buttons on the remote. I always use the top left “ON” button. The dimmer should emit one beep. If no beep, start the whole sequence again.

- wait two minutes. This step is not in the instructions, but I have found it helps make the pairing more likely to succeed.

- use the remote to turn the bulb on and off using the top left and top right buttons, to prove it is paired.

- now just wait and see if the ghost switching returns. Mine generally starts within 5-30 minutes.

- if it is still ghost switching, de-pair the remote by pressing and holding the bottom left button until the dimmer beeps. Start the whole sequence again. Repeat as often as needed until the ghost switching stops (four of my dimmers took 3 or 4 attempts, one dimmer took 17!).


Top tip: if you have more than one dimmer using the same remote, power it/them off whilst pairing the next one to avoid de-pairing one(s) already working. Be aware that powering each dimmer back on carries the risk of it messing up the pairing within the first 5 seconds - I had one dimmer beep (suggesting it had paired with “something else” (that didn't exist, I was in a shielded room)) and ghost switching can return if you are unlucky. It shouldnt happen, but I had it, so it is possible. Power them back on one at a time, and WAIT in between. I suspect there are RF emissions from the dimmer (or electrical circuit) that can interfere with each other. Patience is everything with these dimmers!


I hope that works for you. Let us know how it goes.

I borrowed this r Remote from a friend

I turned off the power and turned it on again, the dimmer entered RF pairing mode, you need to hold one of the buttons for about 5s until we get a double signal from the device. From that moment nothing turns on by itself

   


Andrew.l.owens -> that solved it for me! Thanks
Btw... I didn't use the remote before having this problem. 
But I used it to solve it this way. Only 2 repairs needed!

Jeroen -> Yay, glad it worked for you too :)


I havent had any ghost switching for several weeks now, but I have noticed one of the dimmers doesnt always respond to the remote control. That is solved by holding the buttons down for about half a second. One dimmer seems to respond with just a very short "click" on the switch, but the other seems to need to receive the signal for longer. 


It is such a shame they are not more robust in set-up and operation, as the circuit design, isolation and protection is all actually pretty good. I am also impressed with the latest app, as you can now set scenes to turn lights on at sunset at ANY location. I have mine set to come on when the sun sets in Amsterdam, which is about 15 minutes East of where the dimmers are, so the lights come on BEFORE it gets too dark. 

I am using them with home-assistant and google assistant...

везде брак!

just to check,  I have 8 of these d1. if I get a remote and pair we should be ok?

Chris B; yes, broadly.

You may have to pair with the remote, unlink and re-pair a couple (or more!) times, but they tend to work well once they're working. After a few months, I still have a problem as I've had a couple of times when the main power board to my house trips, and that throws two of mine back to square one regularly. Then I have to go through the process again, and in attempting to re-pair those two I sometimes cause the others to start playing up, but perseverance pays off. I think my main problem is because I have mine in pairs as each room has two light fittings (and I cant wire them with one dimmer for each pair of lights, as there is no neutral at the switch point); that means I have to power cycle both in a pair to re-pair the dimmer that broke in the original power outage, and that sometimes leads me into a cycle of fixing one and breaking the other, until they both decide to play nicely. 

Andrew.owens Just read your feed to Chris. Can I ask where you placed your 2 D1 units if you are controlling a pair of lights in a room? You also said you have no neutral at the wall switch so how is this all connected?

Robert Spary: yes, the no neutral is a PITA for UK wiring. However, when the bulbs are on, there is both live and neutral at the fitting. So, I have a dimmer at each fitting, and leave the light switch hard wired on (I use a connector block). This leaves power and neutral at the fitting to power the dimmer, and then the dimmers control whether the bulbs comes on.


A variation I have also adopted is to leave the original light switch in place, but switched on, with a piece of clear tape to stop me accidentally turning it off. I am finding that makes it easier to reset the wifi remote after a power outage, as I can isolate individual pairs, rather than hitting the circuit breaker for the whole lighting circuit (which also affects the dimmers that may be working, and risks them reverting to ghost switching again). It does mean I cant fit the remote in the light switch position, but for the convenience given my recent spate of power outage chaos, its been worth it.

Got it. I had the same issues with the neutral wire until I rewired my house. I do not have any false switching as of yet but your feed has made me be aware that it may happen. Time will tell. If you are unhappy with the D1 units but still want smart wifi control and remote control switching I have installed a system here which works without fault. You will need power at the light from the rose. You will need to change your light switch to a push switch (easy swap) to turn on your lights and use it as a dimmer. The cost is about the same but you will lose the preset dimmer levels on the RM remote but you can have many remotes as they are basically battery powered RF wall switches the same size as the RM but easier to use in my opinion
