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:

Re: New ESP gadget
what's the point? more expensive than a sonoff and it requires an external power supply...

Re: New ESP gadget
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'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.
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.

Re: New ESP gadget
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?

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?

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).
Re: New ESP gadget
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).manjh wrote: ↑20 Nov 2017, 22:25 I ordered one minutes after I read your post, mainly to see what it can be used for.

Re: New ESP gadget
As an idea, if you need to have the relay on a different purpose than switching mains, one can cut the traces to mains.
Domoticz on Raspi 2 -- 14 ESP units (hacked Sonoff,NodeMCUs, Wemos, self-built units) running with RC140- Mega 2.0.0 dev8
Re: New ESP gadget
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.
Re: New ESP gadget
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!

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.manjh wrote: ↑21 Nov 2017, 17:06Sounds tricky, since you would need to keep the leads to the power supply intact!

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.

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.

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.

Re: New ESP gadget
Regrettable, because i am also interested in very small size - european 65mm wall box compatible relays, which i am unable to find.papperone wrote: ↑22 Nov 2017, 17:45That's beyond an hobbysitc approachLisaM wrote: ↑22 Nov 2017, 15:46 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.
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...

Re: New ESP gadget
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 ![Lach :)](./images/smilies/icon_e_smile.gif)

Re: New ESP gadget
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.enesbcs wrote: ↑22 Nov 2017, 19:13Regrettable, because i am also interested in very small size - european 65mm wall box compatible relays, which i am unable to find.papperone wrote: ↑22 Nov 2017, 17:45That's beyond an hobbysitc approachLisaM wrote: ↑22 Nov 2017, 15:46 If you make it this size, i'll buy ten! https://goo.gl/images/XHULxd

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.
Re: New ESP gadget
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.manjh wrote: ↑22 Nov 2017, 22:26 I've used several KlikAanKlikUit modules that fint into the wall socket behind a standard switch device.

Re: New ESP gadget
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.
Re: New ESP gadget
Shorter wavelength depends more on a "line of sight".
Re: New ESP gadget
Re: New ESP gadget
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...
Re: New ESP gadget
I found a very interesting gadget, at first sight i think it is a Sonoff... after zooming in, i saw that "Smart Home" is the brand..
Has someone met it already? Is it ESP based?

Re: New ESP gadget
Seems like a device that could hold an esp8266 inside. For that price it might be worth testing?enesbcs wrote: ↑21 Dec 2017, 18:57 I found a very interesting gadget, at first sight i think it is a Sonoff... after zooming in, i saw that "Smart Home" is the brand..Has someone met it already?

Re: New ESP gadget
Every successful product is worth copying.

Yes, almost the same price than an ESP Dev Board, but it has a plastic case.grovkillen wrote: ↑21 Dec 2017, 19:08 Seems like a device that could hold an esp8266 inside. For that price it might be worth testing?

I hope it's not made with an RTL based chip.. I just ordered one for testing.
Re: New ESP gadget
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 )
Guys, really.....
Have a Merry Christmas everyone
