💬 Sonoff relay using MySensors ESP8266 wifi or mqtt gateway

[Matthew Ohlson de Fine]

How do you load the relay sensor in Vera after connecting the Sonoff as a wifi gateway as described?

After electricity plugged off , it stops working / not connecting to wifi router, but on manual click it turns on and of , it is problem because I don't use haas config ? I dont know where can I place them, can you help me ? :) thanks

Hi, I see in the instruction a note about not being tested against 220v so just to confirm it is working fine, I've uploaded the sketch to one of those with the power socket plug embedded and I'm able to control it remotely. Great job!
As a side note, I'd copy and paste the "Sonoff specific details" instructions from the sketch also into the build page. My bad because I've missed them and had to google a bit on how to upload the sketch but maybe also others may experience the same.
Thanks

@user2684 Thanks for reporting. I have updated the instructions with the Sonoff details.

Great work!

I was wondering if some of you already know if Espeasy supports the pow versions power usage reporting. I checked the github and couldn't find it. I know Espurna supports it (as a domoticz MQTT). However when I check the REST API of Esputna there is nothing noted about the power consumption (only humidity and temp) requests.

Any help is much appreciated.
Regards, and keep up the good work.

Hi, I have a sonoff device running this sketch since a few weeks now and everything is working great :-) However I've noticed that when the wireless network goes off and then is restored back again the sonoff results still unreachable. When I unplug and plug it again the connection it comes back online. Is this a known behavior? Thanks

[gohan]

is it reachable via IP or is it totally unresponsive?

[user2684]

Totally unresponsive like once disconnected from the wifi (I turn it off from time to time), it is no more able to reconnect. I still need to understand if it happens every time so I was wondering if this was somehow expected or not :)

I had same problem too.. When is longer not turned on, Sonoff disconnects from wifi , that ip is not in client list, in my case I only turn sonoff on throught black button on the top and than it is okay about day-two.

I have few sonoff and I just installed one with this script to replace a dead 433 device. So thank you very much for the script and the tutorial.

Reports of regular wifi connection losses are what kept me away from sonoff until now. Maybe the script could check wifi connection regularly and force a reconnect. Something like in the link below ?

Another I have had these running posts.

I have had 3 Sonoff relays running on 240v 50Hz for 2-3 months straight.

2 of them in IP67 outdoor lights with Phillips LED Lamps, switch on and off several times per day, Not a single hardware issue.

best $6 ever

@betonishard ESPeasy I am not sure, but supposedly Tasmota does

Yes over one month and very reliable, but with Domoticz is not integrating very well with my old 433MHz remote controls (that I use for my remaining 433MHz module until they are replaced).
Making me think about a small plugin board to control the sonoff through serial port, so it would make a real MySensors node for 10$ and avoid all the power supply, relay etc etc soldering and not rely on wifi.

[gohan]

I remember reading non to connect any other serial device while the Sonoff is connected to mains or it would get damaged.

[Ed1500]

@gohan The only time you would need to connect a serial device is I guess when you are flashing the software. There is no needTheThe only time you need to connect a serial device is when you are flashing the software. There is no need to connect it to the mains grid then. Whether it would damage anything i do not know but it is unnecessary and therefore absolutely not recommended to do it. Avoid working on anything that is connected to mains, especially if there is no need to have it connected

[gohan]

I was referring to what @Nca78 said about controlling the sonoff through serial port.

[Ed1500]

@warmaniac you might have solved yr problem already. Anyway, I use the github/computourist software for the SonOff. have been using it for many months. very stable

[Ed1500]

@gohan ah ok. Sometimes I lose track of who is reacting to who. Must be old age :-)

I supposed that's when you connect your computer to sonoff using serial adapter ?
I see no reason for damage if both es8266 and atmega are connected to the same VCC/GND.

[gohan]

I think it's because the gnd on the sonoff is shared with neutral from the mains. I have seen pictures of burned stuff but I actually never wanted to try to see if the computer gets fried or not 😁
