Nice work! Did you used the latest Mega sources to compile?
Finally I am also able to apply puya patch and compiled some binaries (with P165) for testing, attached on the first post of this thread.

Yes, I used sources from yesterday and patched Esp.cpp and obviously your nice plugin.
Working well witch domoticz ESP-01s and LC TECH single relay.
Added a button and some rules to get full feedback about relay state.

Code: Select all

on sonoff#Relay0 do
Publish domoticz/in,{"idx":92,"nvalue":[sonoff#Relay0],"svalue":""}
endon

on Przycisk#switch do

if [sonoff#Relay0]=1
relay,0,0
else
relay,0,1
endif
endon

Przycisk is a name of switch input connected between GPIO-2 and GND Switch type" Push button active low" with internal pullup.
Whatever I use to change relay state (button, external command etc.) Its show always real state in domoticz.

I'm successfull with 3 of 4 Module with ESPEasy_R147_1M_64kS. The forths also first works fine until I tried to change the IP-settings. After that I can reach it. Even after several successful flashes with different FWs it is not visible in the WLAN. I'm not so really a profi in this topic, but I'm wondering that the simple change of the IP-settings can have this effect.
Next I'll try the version of @xury.

EDIT:
Wonderfull, the problematic ESP8266-01 is running now, with the changed IP configuration and with the FW of @xury. Now I have to connet it with the relay.

Thanks a lot both of you!

I bought 4 relays from AliExpress from this user.
https://www.aliexpress.com/item/ESP8266 ... 88295.html

None of them works.
I tried send the serial command A00101A2 and A00100A1 in hex to the device directly from my computer using the utility downloaded from LCTech. No response from the relay.
I probed the signals on the serial port with a oscilloscope, they looks perfect.

Is it possible the relays are faked? The MCU on the relay does not work? Or it takes a different command?

I'm totally lost.

There are several devices on the wild which is not programmed, you need a programmer, the STC15F104W microprograms can be found at:

That's should be exactly what happened to my relays. I contacted LCTech, and they said those relays were not made by them.
I will try to program them.

Thank you!

Is there a way to read our the binary code from MCU of the official LCTech product and use it to program my relays?

Programmed the MCU of relay with the hex code from the post. And the relay works now. Well, sort of.
The LED works, it turns on and off with the on/off command, but the relay does not switch.

The problem is that the R3 is too big. It is 10K instead of 4.7K from LCTech. Once I changed it to 4.7K, it worked.

Nice work! I know that counterfeit's sometimes missing software, but never tought that they are incompatible at hardware level. If i were you, i would ask for refund.

Less than $5 for 4. Not worth the hassle to ask for refund.

Hi Xury,

I have an LCTech Relay X2 (2 relay module). The stock firmware on the MCU and ESP worked, I was able to control the relays with HEX codes over TCP. I flashed your ESPEasy_1M_128kSPIFFS_PUYA.bin to the ESP-01 (not a PUYA chip). ESP Easy works. I configured it in the following way:
Device: Serial MCU controlled switch
Name: Relay
Enabled: X
Switch type: LC TECH
Number of Relays: 2
Serial speed: 9600
Use command doubling: NO
Send to Controller: X
Interval: 0
Names: Relay0, Relay1, Relay2

I also configured a OpenHAB MQTT controller. I am trying to send 0 and 1 to /LCTech/Relay/Relay0 but nothing happens. The device and MQTT definitely works as I am getting the RSSI and update messages from the System Info devices that I have also created. When I am sending the MQTT messages to the above relay topics, nothing is appearing in the Log.

How can I check this further? Can I switch the relays from the Webserver?

Thanks,
Csongor

You have to implement MQTT support if you wish to use it.

Currently the plugin can be used with the following commands:

The ON command for Relay0:
relay,0,1
The OFF command for Relay0:
relay,0,0
The ON command for Relay1:
relay,1,1
The OFF command for Relay1:
relay,1,0

Commands can be executed on the web interface directly, or in a user-written RULE, or with a HTTP URL:
http://ESPEASY_IP/control?cmd=relay,0,1

Or command through MQTT (from ESPEasy wiki)
<MQTT subscribe template>/cmd with payload: <command>

Is it possible that this 2 relay module is somehow different? I tried the HTTP commands. First of all there is no HTTP response (empty head and body) (I am not sure if that is intentional or not).

I see the following in the log after I issue the HTTP command:
228095 : EVENT: Relay#Relay0=1.00
228097 : EVENT: Relay#Relay0=1.00 Processing time:2 milliSeconds
228098 : EVENT: Relay#Relay1=1.00
228099 : EVENT: Relay#Relay1=1.00 Processing time:1 milliSeconds
228100 : EVENT: Relay#Relay2=0.00
228101 : EVENT: Relay#Relay2=0.00 Processing time:2 milliSeconds
228110 : MQTT : /LCTech/Relay/Relay0 1
228110 : MQTT : /LCTech/Relay/Relay1 1

I am not sure why there are relay 0, 1 and 2 when I have configured that I only have 2 relays. But I guess that should not cause any issues.

Yes, there are multiple variants of this relay, some of them also have hardware bugs. (power supply inefficient so they auto restart when relay is on)
relay number 0 is always the first relay, and 1 is the second one on every supported device, it does not matter how you name it - the commands using their hardwired number.
There will be no HTTP response, we never know if the command is succesfully completed, because there are absolutely no answer from the device, nor any option to check the relay active status. I can modify the code the output some meaningless text, such as "command completed", if anybody need it.

According to riker 115200 baud is the necessary setting. Save than power off&power on the device, and check if it works. If nothing helps you can try other speeds, and for last resort: command doubling.

This for anyone who would like to setup ESP Easy for a LCTech Relay X2 board. Thanks for the guys here for making this happen and helping me getting it working with my relay board.
I got mine from ICStation.com: http://www.icstation.com/esp8266-wifi-c ... 12593.html

My model came with a ESP-01 NOT with a PUYA flash chip. But the firmware is PUYA compatible, so it should work with an ESP-01 with PUYA

This is how my board looks like:

: IMG_20180508_085722.jpg (383.79 KiB) Viewed 124186 times

And the back of the board:

: IMG_20180508_085740.jpg (411.79 KiB) Viewed 124186 times

Flash ESPEasy_1M_128kSPIFFS_PUYA.bin firmware to the ESP-01. You can find the link to the firmware on Page 12 post #120 of this thread.

Perform the basic settings of the ESP Easy (wifi, etc.)
I set LCTech as my unit name (it will be important for MQTT later):

: Esp_main.png (19.79 KiB) Viewed 124186 times

Add the following in the Device section:

: ESP_device.png (53.75 KiB) Viewed 124186 times

Of course your can rename the Relay0, Relay1 names at the bottom. Ignore Relay2.

I set up MQTT with the following settings:

: esp_controller.png (50.08 KiB) Viewed 124186 times

Save the settings and power cycle the relay board. When I power up the board, the red LED (D7) is lit and after a few seconds the green LED (D6) starts flashing. And it will stay that way. The board is ready to receive commands. So far I am controlling it via HTTP and MQTT the following way:

HTTP commands:
Relay 0 Off: http://ESP_IP/control?cmd=relay,0,0
Relay 0 On: http://ESP_IP/control?cmd=relay,0,1
Relay 1 Off: http://ESP_IP/control?cmd=relay,1,0
Relay 1 On: http://ESP_IP/control?cmd=relay,1,1

MQTT commands:
Topic: /LCTech/cmd (of course this may change depending on the Unit name)
Payload:
Relay 0 Off: relay,0,0
Relay 0 On: relay,0,1
Relay 1 Off: relay,1,0
Relay 1 On: relay,1,1

With the above setup, you will be getting MQTT messages on /LCTech/Relay/Relay0 or /LCTech/Relay/Relay1 topic with payload of 0 or 1 when the relay status is changed either via HTTP or MQTT. There is no status message back via HTTP. Keep in mind that this is not based on the actual status of the relay, as the MCU is not sending status information / confirmation back to ESP.

Hello,
I have problems with the configuration, post programming
Configure the wifi connection, I wait for 20 seconds but when I try again
I do not go ahead, I always stay in the wifi configuration.
What programmer should I use for flash esp-01?
sorry for my english, I use google translator.
thank you

I used a CP2102 (not FTDI) in such connections to program it:

with DOUT mode and of course with the proper PUYA-safe binary.
If it stays in wifi config mode after programming, than power off&power on the module and retry.

The first was compiled with the newer lwIP 2.0 stack, the other compiled with the old lwIP 1.4. The older supposed to be more stable, but you can try and see.

Fair enough, Domoticz really shows an error, if reply did not arrive to the GET command. Now i am replying with an "OK" message, Domoticz error message disappeared.

xury wrote: ↑09 May 2018, 12:14 It would be nice if the response would be in JSON format.

Exactly what JSON message did you mean, and for what purpose? Domoticz did not care about replies from "Switch" devices as i see.

xury · #147 Post by **xury** » 11 May 2018, 14:20

Yes you have right. Domoticz does not care about switch reply.
So simply OK will be good.

Maybe i have to inject somehow md5 hash into "runTimeMD5" after compiling, but honestly i I do not see its practical significance.
Until appearing more detailed information in here:

this bug stays in "wontfix" category.
Or i will simply delete it completly before compiling if it will be annoying.

Would I be able to solder on the chip

sorry is this is a stupid question, but will your firmware work with the Sonoff T1 2Gang (similar to the dual?). I both 2 and want to be able to control them using ESPEasy and Domoticz.

This plugin will not work with any Sonoff T1. According to Tasmota wiki:
"When pushing a button, the touch chip lift the power high to the EFM8BB1, and the EFM8BB1 chip ties the signal line for each button low, for the full duration of the keypress. There is no serial data, that i have seen at all."
The device's operation is somewhat obscure to me, i am using my own T1 2Gang with Tasmota without problmes.

Ok the commands seems consistent, i expanded the plugin to support 4 relay, now it can be selected in plugin options.

This plugin will not work with any Sonoff T1. According to Tasmota wiki:
"When pushing a button, the touch chip lift the power high to the EFM8BB1, and the EFM8BB1 chip ties the signal line for each button low, for the full duration of the keypress. There is no serial data, that i have seen at all."
The device's operation is somewhat obscure to me, i am using my own T1 2Gang with Tasmota without problmes.

Hey Enesbcs

do you use the web or MQTT component for this? (On Tasmota)

Kind regards

I am using the Tasmota MQTT with Sonoff T1, works perfecty with my Domoticz server.

Hi, thank you very much for your work.
I have a problem with the webinterface. when i click on Devices and add a Serial MCU controlled switch, then I can't edit the device. The ESP-01 makes a restart.

You're right... i left out one index, and ESP did not honor buffer overflow.

Try the updated binary.

Very new to all this so forgive me.

Had one of these laying around as it was useless in its original state. Managed to flash the firmware and get it working.

I wish to use it to control a garage opener that only requires a momentary switch. Is it possible to do that with this?

Have tried the pulse command but had a feeling it wound not work and I was correct.

At the moment I have a script setup in home assistant that turns the off after 1 second but find this is more like 2 or 3 seconds. The script is a very crude way to do what I want so was hoping for a better solution.

What device? This plugin supports some kind from Lctech, Tuya, S.Dual.. be a little more specific. I think it can be done with EspEasy rules.

Sorry about that, referring to the 12v LC Tech single channel relay (same one as the post at 116)

I see. You have to enable rules in Espeasy advanced settings, then if the serial device name is "lc" and the first relay named as "Relay0" (default) then the code below switches off the relay one seconds after switched on. It has to work, if somehow not, then i will ty to implement it inside the plugin.

Code: Select all

on lc#Relay0>0 do
 timerset,1,1
endon

on Rules#Timer=1 do
 relay,0,0
endon

Will give it a go when I get home in an hour or so.
