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.
i removed all mentioned resistors and now it is not working neither via app and remote, so be careful...
Are there any other devices where this just works? its driving me crazy and I'd prefer to just replace.
Chris B, I got the DM1 for the scheduling feature. I did not purchase a remote as I thought the app would be all I would need. After months of possessed lighting in my iguana enclosure I opened a trouble ticket with Sonoff who were kind enough to send me a remote. The instructions I got from Sonoff were vague, at best. After some digging, I found this on page 5 of this thread:
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!
Thanks for the tip. I removed the given resistors (R6 R7 R8 R9 + R11 R12 R13 R14) and now there is no ghost switching anymore
Hii folks. It seems that the ghost switching problem of the sonoff dimmer still excists. Most of us don't understand electronics, soldering, and flashing and blablabla. But understand only basics like connecting lamps and stuff.
So I came up with the idea of wrapping the dimmer in alluminium foil to kill possible external RF signals. (I saw something on youtube of Dr.Zsss who said something about external signals, and frequencies and stuff and he started to solder again :( ) and since I fitted the dimmer in a junktion box anyway for safety, I wrapped the whole thing in aluminum foil. And guess what. I didn't help, the light just went on. And since the app doesn't have a log function for the dimmer we never can tell what triggered it. AND maybe it's a coincidence but ever since I got the dimmer my google nest hub seems to have problems too, it keeps telling me something went wrong when I use voice commands. When I tap the screen to switch things on/off it works just fine. So just now I reset the google hub to factory settings to exclude any coincidences. I hope Sonoff comes up with a solution because I'm convinced it's the dimmer itself. Maybe make a option in the ewelink to switch on/off the RF function. Or (even beter) they solve the problem. I saw posts from 2 years ago!!!! I wonder when.
