💬 Sonoff relay using MySensors ESP8266 wifi or mqtt gateway

[warmaniac]

@Efflon said in Sonoff relay using MySensors ESP8266 wifi or mqtt gateway:

@warmaniac the sonoff works just like any sensor except its configured as a gateway since that is what is needed for esp8266+mysensors . Mqtt or ethernet/wifi is just a matter of taste and your setup, skip mqtt if you don't have anything else using it.

I want to use standalone Sonoff (one device) than I must install broker (Mosquito) on my raspberry where is Domoticz running ? And how can I add than that device or how can this setup looks like.

[Efflon]

@warmaniac You dont need mqtt/mosquitto. Just follow the guide at https://www.domoticz.com/wiki/MySensors for adding a "MySensors Gateway with LAN interface (Ethernet)" then follow the ethernet sketch here https://www.openhardware.io/view/318/Sonoff-relay-using-MySensors-ESP8266-wifi-or-mqtt-gateway

[warmaniac]

@Efflon

Tried LAN sketch after adding new hardware in domoticz this error occurs

2017-04-06 06:28:07.230 MQTT: Connecting to 192.168.2.209:5003
2017-04-06 06:28:07.335 Error: MQTT: disconnected, restarting (rc=2)

after that Sonoff blik twice. What may be wrong ?

Edit:

Understand now , it is added as classic mysensor LAN gateway , now working fine ! I tried to do it complicated way , but it was easy

[Efflon]

@warmaniac Excellent!

[Bryden]

Does anyone know how I can request the current state of the relay via MQTT.

Eg HASS has rebooted, forgotten what state the switch was previously in, then it wont work untill power is cycled to the sonoff.

I want to send an MQTT message to the sonoff to get its current state. Tried looking over the forums and page and cant seem to see anything about requesting a state from a binary switch / relay actuator

[martinhjelmare]

@Bryden

If you're using the mysensors component in home assistant, you can activate persistence to load devices and last known state when home assistant restarts.

Another option is to use the retain flag when publishing mqtt messages from the gateway. Support for this has been added in mysensors dev branch:
https://github.com/mysensors/MySensors/pull/793

[Matthew Ohlson de Fine]

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

[warmaniac]

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

[user2684]

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

[Efflon]

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

[betonishard]

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.

[user2684]

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

[warmaniac]

@gohan said in Sonoff relay using MySensors ESP8266 wifi or mqtt gateway:

is it reachable via IP or is it totally unresponsive?

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.

[Nca78]

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

[Ed1500]

@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

[Nca78]

@gohan said in Sonoff relay using MySensors ESP8266 wifi or mqtt gateway:

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

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

[Nca78]

@gohan yes with it could happen, but if you just connect a standalone Arduino powered with VCC GND from esp8266 there's no reason to have a problem.

[gohan]

But why would you want to connect another arduino to the sonoff?

[betonishard]

@Ed1500 Thanks for your answer. Went for espurna.. Tested tasmota, but compared to espurna it was kind of slow. Works stable for quite some time now.

[Ed1500]

@betonishard Good to know. I was thinking about trying Tasmota for regular Sonoff, but I will keep slowness in mind

[Nca78]

@gohan said in Sonoff relay using MySensors ESP8266 wifi or mqtt gateway:

But why would you want to connect another arduino to the sonoff?

To have a real MySensors node that can be directly controlled with another node and not relying on wifi and controller.

[gohan]

Sorry but I am still missing the point. If you have to make a mysensors node anyway, why not make a classic relay node?

[Nca78]

@gohan because when using the sonoff I do not have to care about the power supply/safety, to find a case that is safe for electrical device and I only have a few things to solder.
And sonoff is cheaper than buying separately the power supply, case, relay etc

So just solder a few low voltage components on a PCB, plug in the sonoff and get a safe main powered actuator.

Not 100% sure it's worth it yet, still thinking a out it
But main advantage is to reuse it in more complex sonoff devices with multiple relays, power measurement, in wall plugs etc etc

[gohan]

Once you come up with something I'll take a look to better understand what you want to do
I have seen how to hack some of them to add a couple of wires directly on the esp8266 chip to get an i2c bus.

[Jonathan Caes]

How can I create a new device in Vera for a gateway? Can't seem to get that working

[Jonathan Caes]

@efflon Do you know how I can setup the sonoff gateway on the Vera Edge? I used the MySensors plugin to add the sonoff to the network but can't get the relay to toggle.. Help is much appreciated!! Thanks!!

[tkald]

If someone wants, I create a modification to cooperate with DHT22. Data pin of DHT22 is connected to pin 5 of sonoff.

 * DESCRIPTION
 * The EthernetGateway sends data received from sensors to the WiFi link.
 * The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
 *
 * VERA CONFIGURATION:
 * Enter "ip-number:port" in the ip-field of the Arduino GW device. This will temporarily override any serial configuration for the Vera plugin.
 * E.g. If you want to use the defualt values in this sketch enter: 192.168.178.66:5003
 *
 * LED purposes:
 * - To use the feature, uncomment any of the MY_DEFAULT_xx_LED_PINs in your sketch, only the LEDs that is defined is used.
 * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
 * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
 * - ERR (red) - fast blink on error during transmission error or recieve crc error

[Morten Mathiasen]

I think it is an easier and more general solution to use https://github.com/arendst/Sonoff-Tasmota

[gohan]

@Morten-Mathiasen that is the one I'm using on my sonoff pow

[dbemowsk]

@Jonathan-Caes said in Sonoff relay using MySensors ESP8266 wifi or mqtt gateway:

Do you know how I can setup the sonoff gateway on the Vera Edge?

I am using a Vera Plus. I did not go the route of MySensors for my Sonoffs. I use the ESP Easy firmware with a slightly modified Vera plugin. Here is my BLOG post on how to do it.
https://dan.bemowski.info/2017/07/04/using-a-sonoff-with-espeasy-and-vera/

You could still go the MySensors route. I just figured I'd show another alternative to this.

[Jan Gatzke]

It's a shame that we cannot have both, mysensors and the ESP Easy stuff. There has been a project for this: https://github.com/letscontrolit/ESPEasyMySensors

[dbemowsk]

@Jan-Gatzke It is my understanding that ESP Easy can send and receive MQTT messages, couldn't you just use a MySensors MQTT gateway if you wanted to keep it on the MySensors path?

[Jan Gatzke]

@dbemowsk You cannot because MQTT is just a transport and not a strict data format. You can however use MySenSors MQTT + ESP Easy MQTT + a broker + node red + a controller. Node Red can do data conversions and integrate everything.

[dbemowsk]

@Jan-Gatzke I was just speculating. I do not use MQTT, so I am by no means an authority on the subject.

There is no real benefit to have the sonoff running mysensors instead of other firmwares, if your controller is able to communicate over mqtt to switch on/off the relay, you are fine

[Jan Gatzke]

@gohan I know some controller are aware of ESP Easy via MQTT. If you controller does not support this directly, you have to integrate it manually (with node red). In my opinion scenarios, where MySensors with ESP Easy frontend would be of use, do still exist.

IMHO there is one, when your controller is down, gateway is down or whatever, you could still have direct control or the light switch from a MySensors button with node to node communication.

[gohan]

How do you do that if the sonoff is only having wifi?

[Nca78]

@gohan said in Sonoff relay using MySensors ESP8266 wifi or mqtt gateway:

How do you do that if the sonoff is only having wifi?

Ah yes in that case you can't and yes there's no benefit

[gohan]

A wired button would be a much fail safe option for sonoffs

[Jan Gatzke]

@gohan won't this option miss some features?

[gohan]

@Jan-Gatzke for a sonoff there aren't many options and also a wired button you are pretty sure it would always work.

[dbemowsk]

For the Sonoffs, you could wire an external button directly to the onboard button which is on GPIO 0, or you could wire it to GPIO 14 which is broken out on the programming header on most Sonoffs. Some older Sonoffs didn't have GPIO 14 on that header. Once you have a button or switch wired on, you can then change the code or do some firmware scripting depending which flavor of firmware you use.

[sam9s]

@dbemowsk Do you know if there is a way to use vera edge / plus with Tasmota firmware instead of EasyESP??

[dbemowsk]

@sam9s I have never played with Tasmota, so I have to say that I don't know. A Vera plugin would have to be coded or modified as I did with the HTTP Switch plugin to make it work if there is not one out there already. I am assuming that you looked at my blog post on the ESP Easy way.

[gohan]

Can the Vera plug in work with mqtt?

[dbemowsk]

@gohan Here is a plugin for MQTT using Vera. You would still need to have an MQTT Broker set up though. I am surprised that there is not an active MQTT plugin for Vera in the plugins section. Didn't find anything when I did a search for MQTT.

[gohan]

I was just asking since tasmota works great on mqtt

[tripy]

I will just leave that here for other like me that wondered for hours why they could flash their sonoff, but it did not react once plugged to the main.

You need to setup your arduino with DOUT as flash mode.
Other mode will flash without errors, but the device will appear bricked.
My settings where:

@tripy yes, you are absolute right - you need to set the flash Mode to DOUT for flashing the newer SONOFF generation (the SONOFF's with the hidden green LED).

Hello!
Maybe someone here has a code for Sonoff RF with support 433 MHz receiver?

In my opinion, paired with a wireless wall switch, this will turn out to be quite a cheap and convenient solution for lighting control.

The cost of a set of relay and switch about 10 dollars.

Did you try this?

@electrik Now I just read the description of this firmware. To do this, I need to understand how to work with MQTT. I hoped to find a simpler solution. Ethernet gateway is much easier to connect.

[electrik]

Mqtt Is really easy to use in fact. Just follow a tutorial to install mosquitto and you're ready to go.
It also depends on your controller of course

@electrik Thanks you! Now I will order everything I need on TaoBao in China. I just yesterday learned about the existence of the Sonoff module with 433 MHz radio support and wall switches for them.

@vladimir what controller are you using? Most home automation controllers like domoticz and Home Assistant have a quick integration with Tasmota or EspEasy

[vladimir]

@gohan I use OpenHAB 2. As I understand it, it also integrates well with Tasmota.

good, give it a try
