Anyone seen Xenon WiFi Touch Switch? It's more expensive than Sonoff Touch...

Would love to flash them with ESPEasy, as it is a real delight to work with, and easier to keep all devices around the house on one system.
The most important code regarding the Dual from Espurna seems to be this snippet:
...
I hope I can find some time somewhere in the next weeks to fiddle a bit around with the dual.
I'm looking forward to the testers of plugin 165... :)

There are also a direct approach of the Sonoff Dual control by bryan:

Oh that's great, must have overlooked this one. I hope I can find some spare time the next coming days to give this a try!

Thanks for your off topic information.

I now have my pow reporting in to domoticz with your help still lots to learn.
ESPurna works great and I do see the POW as separate to the other sonoff products I'm running.
Life control circuits need to be handled with respect.

I tried ESPurna, but i can't get it to work on my Sonoff Dual. It fails at the start, while trying to connect.
I'll just forget about this Sonoff stuff. It sounded great, but it's just a disappointment to me now.

Now i have to figure out a way to flash the original firmware back onto it.
Did you try to flash the compiled source as it is published by the maker of espurna ?
You can find all the Sonoff precompiled firmware bin_files here:
https://bitbucket.org/xoseperez/espurna/downloads/
I think it can work on your dual relais or 4 channel relais very well if you follow the right steps.


Now I will go offtopic a little but this is my very positive experience with espurna:

I flashed my Sonoff-POW with Espurna and it works great. I compiled it myself with Atom editer and PlatformIO plugin. I work under linux and followed this guide:
http://www.cnx-software.com/2016/12/03/ ... ss-switch/

In linux or windows:
After flashing you login on 192.168.4.1 , username is admin and password is fibonacci. The first thing the firmware wants you to do is create a new password.
New password needs minimal 8 characters with at least 1 Capital and 1 Number.
Than you enter your own user/pass for your local WiFi network and go to there.
There fill in your MQTT Server_IP and Topic_name (I left topic unchanged).

As I use Domoticz I went to the Domoticz tab on sonoff-pow internal webserver and filled in 5 Idx numbers earlier created in Domoticz as Virtual sensors.
1 Power sensor type: Usage_Electric , registers in Watt
2 Energy_Increment type: Counter_Incremental , registers in kWh (WattHours)
3 Voltage type: Voltage , registers in Volt
4 Current type: Ampere(1 phase) , registers in Ampere
5 Switch type: Switch
Enabled a Domoticz hardware device called: MQTT Client Gateway with Lan Interface. IP is IP of my local RasPi server and the port is 1883. The publish topic i set to ´out +/´ .
You can even calibrate the Sonoff-pow in the webinterface by connecting a known resistive device (lamp or heater) and fill in the measured Watts, Current and Voltage in the Power tab and update these values.

I think Espurna is great software and, as most Sonoff´s are dedicated devices, there is no real need to integrate any of the Sonoff devices in ESPEasy. You can so easy use the precompiled source code from Xose Perez from bitbucket.

Have you look the distance between relay pins (NO/COM/NC) and the ESP pins?
Would you consider have main live so close to the digital pins of the microcontroller? Not me!

In my design I use minimum 15mm or if this is not possible I add a "cut/hole" in between to separate high/low voltage traces...

Just in case anyone is running into problems after flashing the new Sonoff S20 plugs (or maybe others as well)

Sonoff flashes as usual, but after reset (plugging in AC) there is now Wifi AP as the device just hangs. New boards are either delivered with ESP8285 or need DOut reset mode.

Not new, but anyone has tested the followin ESP relay?
https://www.ebay.com/itm/ESP8266-ESP-01 ... 2864309446
It has a greater brother that has a serial MCU between the relay and the ESP-01, but this smaller version (yellow socket, no serial pins) is working similarly?

As far as I can see it is 8266 based!
See this one at Banggood:
https://www.banggood.com/search/esp-01s ... odule.html
I think that would take this unit:
https://www.banggood.com/Upgraded-Versi ... rehouse=CN
So the ebay offer is not bad at all!

The pictures at banggood are better.. I do not see other MCU, the relay perhaps directly changed by GPIO0 of the ESP-01?

It looks like a very simple device, so I assume you are right.... anyway, the risk is low (only a few Euro's).

I am sure that a Sonoff would be better, but it's size is impressive: 37 x 25mm.
It's in my shopping cart more than an hour, viewing pictures from every angle, thinking about it... then i realize the truth in manjh's post and buy one. :) I'll see what can this be used for.

I ordered one minutes after I read your post, mainly to see what it can be used for :) .

The argument about Sonoff is valid, but Sonoff has different features.
It is powered directly from 230V, which can be an advantage. On the other hand it can also be a disadvantage if I want to switch anything else than 230V mains.
Also, the Sonoff is bigger. This unit could be easier to build into a device, provided there is a 5V power source available (or enough room to add a small 5V power supply).
So: there is no winner, both devices are different and useful (I hope).

I agree there's no winner, I was assuming that if you need to switch AC load, then sonoff is more self-contained and for this other board you need external 5VDC to be supplied (that will make not easy to fit the units, considering as well the power supply).

As an idea, if you need to have the relay on a different purpose than switching mains, one can cut the traces to mains.

On a Sonoff you can't, since the power supply for the ESP part is drawn from mains.
On the little device in this topic: you don't need to, since the relay will only be used for switching, so it doesn't really care what is attached.

That is exactly what I am trying to point out. You can achieve the same functionality with a Sonoff, you just need to cut the traces connecting mains from input clamps to the relay. Then you can switch anything.

Sounds tricky, since you would need to keep the leads to the power supply intact! Remember the ESP part of the Sonoff is powered that way.
Also, you would have to make new connections to the relay.
I think I would rather go for a separate NodeMCU with a relay board, which is effectively just what this small device is.

Sure, I got nothing against the small device, and if you buy for the purpose, it is undoutbely better than "open heart surgery" on a sonoff.
However, often one finds the situation where you just have a sonoff lying around and want to switch "something DC"... then cutting the traces and making a new connection can be an option.

I've my own custom made solution, which is way better than sonoff, up to 3 relays and can control anything from 230VAC down to 5VDC :mrgreen:
https://www.letscontrolit.com/wiki/inde ... ule3xRelay
It's small enough (80x60 mm) and I just need to design an enclosure fro external use (not top priority as I'm already using many of those inside junction boxes)

PS: it also has a full ESP8266 with 4Mb flash mem and all pinout brough out to pinheaders for easy connection of additional devices (I use those pins for temperature sensors and PIR devices)

never thought about it, if you are able to assemble it I can share the gerber files but consider all discrete components are SMD...

One of the most densly packed esp8266 i ever saw: https://github.com/JanGoe/esp8266-wifi-relay
48x48mm...
I once asked itead for even more densely packed 8266, an micro module. Never heard back from them...

I know this design Lisa but IMHO it's too packed with several issues:
1) the ESP8266 antenna is somehow blocked and I'm certain the quality of WiFi can't be that good
2) GPIO15 pulldown is done without resistor :o
3) Resistor to the mosfet gate is too big (100K?)

As an idea, if you need to have the relay on a different purpose than switching mains, one can cut the traces to mains.
On a Sonoff you can't, since the power supply for the ESP part is drawn from mains.
On the little device in this topic: you don't need to, since the relay will only be used for switching, so it doesn't really care what is attached.
That is exactly what I am trying to point out. You can achieve the same functionality with a Sonoff, you just need to cut the traces connecting mains from input clamps to the relay. Then you can switch anything.
Just cutting traces on mains power lines is not a good idea.
For 230V you need to keep a gap of at least 3 mm or else it could create an arc between the copper lines and thus isn't safe to touch.

Sorry for my ignorance but what is the main error with doing it this way? I have an ESP-01 that I'm trying to control my projector with and I pull the CH_PD high with no resistor.

Connecting 3V3 directly to a PIN basically you are not limiting the current that can flow, thus you can damage the (delicate!) pin of the ESP8266...
I know it's not commonly to happen but, with the cost of a resistor I think it's worth to protect the MC, which is a pain in the a$$ if you need to replace it (talking about ESP-12F)

On Top:
GPIO15 needs "low" at startup for booting from the correct memory (GPIO15 = "high" says boot from SD-Card which ist not supported by ESPEasy).
If the ESP is running GPIO15 is a usable GPIO. If you connect GPIO15 directly to GND it can't be used for anything.
It should be possible to connect GPIO15 to GND with a 10 KOhm resistor and with a pushbutton to +3.3V so you can use it as a button input for example.
Just on Bootup the button should not be pressed.

It's same as with GPIO0, just GPIO0 has to be "high" on boot or you'll run into flash mode.

I know this design Lisa but IMHO it's too packed with several issues:
1) the ESP8266 antenna is somehow blocked and I'm certain the quality of WiFi can't be that good
2) GPIO15 pulldown is done without resistor :o
3) Resistor to the mosfet gate is too big (100K?)
4) No RESET button (and with module connected to MAIN I wonder how you can do it in a safer way
5) CH_PD is pulled high without resistor :o
6) GPIO0/2 shoudl be pulled high at boot for proper boot
7) GPIO0 is floating and I'm sure this can lead to random issues
8) Relays are driven directly while I believe an optocoupler gives better protection to spikes
9) SDA/SCL signals are not pulled HIGH and this can cause issues with some I2C devices

I'm sure there are other issues but above list is long enough for me to classify this module as "I don't like it" :D
If you make it this size, i'll buy ten! https://goo.gl/images/XHULxd
Anything (much) bigger then that means it no longer fits and then size no longer matters. It's the reason i still have zwave, all others zwave modules are phased out in favor of esp.

That's beyond an hobbysitc approach :)
I'm sure it's doable, but the investment behind (time and money) won't be affordable if not aiming to a commercial product line...

Regrettable, because i am also interested in very small size - european 65mm wall box compatible relays, which i am unable to find. :( I have no intentions to make one on my own, but if something can be hacked easily, i am interested.. :)

I'm not familiar with northern EU standard, in Italy the junction boxes are 10x10cm (9x9 internal space) and standard wall plug is 85x55mm so plenty of space :)

I've used several KlikAanKlikUit modules that fint into the wall socket behind a standard switch device. It works, but in my experience the reception is slightly less than the plug-in devices. Probably has something to do with cables and metal (of the switch) taking some of the RF reception away.
So using a small device with an even smaller antenna, that is also partly covered.... not sure! Maybe Wifi signals are not as much hit by this effect.

Zwave is using 868MHz, Wifi 2.4GHz. So in theorie wifi should operate better in a wall then zwave due to the shorter wavelength. Zwave is working just fine at my home, so wifi should do better.

The only one i could find is in the link i shared, that is small enough (barely though). Papperone's southern europe's junction boxes are hugh compared to mine (nothern european) boxes, they will never fit.

Shorter wavelength depends more on a "line of sight".

It would take a vertical metal plate to do this kind of shielding, due to the low bandwidth requirements from espeasy an echo would be enough to connect to the ap.
I have three unifi's with overlapping reach sharing the same ssid, so it would still connect to another ap in the case something would block one side. To make it unreachable, you would need to have a faraday cage...

Seems like a device that could hold an esp8266 inside. For that price it might be worth testing?

Yes, almost the same price than an ESP Dev Board, but it has a plastic case. :)
I hope it's not made with an RTL based chip.. I just ordered one for testing.

USD 3.71 for a copy with questionable content and quality vs USD 4.85 for the genuine Sonoff basic (actual price from the Itead.cc website https://www.itead.cc/sonoff-wifi-wireless-switch.html )
