Re: Serial MCU controlled relay/switch
Heyhey
Looking further : would I be able to use this to flash it? Looked at the above link, but don't have a 3.3 + GND on the print.
Would I be able to solder on the chip
https://docs.tuya.com/en/hardware/WiFi- ... e-mcu.html
pin 16/15 and 12 for comms and 8 and 9 to put 3.3V on it?
Kind regards
Steve

and don't bother going any further, I just literally burned some of the traces... To be honest, crappy PCB

Still have a Sonoff Touch 2-gang to go with

Re: Serial MCU controlled relay/switch
Hello,
I have a LCTech Relay X4 board. I installed ESPEasy on the ESP-01 (ESPEasy_1M_128kSPIFFS_PUYA.zip) and the first two relays are in function, but the last two relays are not contolled.
What can I do to use all four relays?
I would like to control with HTTP commands:
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
Relay 2 Off: http://ESP_IP/control?cmd=relay,2,0
Relay 2 On: http://ESP_IP/control?cmd=relay,2,1
Relay 3 Off: http://ESP_IP/control?cmd=relay,3,0
Relay 3 On: http://ESP_IP/control?cmd=relay,3,1
Who can help me?
Thanks

Re: Serial MCU controlled relay/switch
Hi,
I've never seen a 4 relay version, can you provide me the link or the datasheet, to find out what serial commands needed to operate it?
Re: Serial MCU controlled relay/switch
Hello,
Relay control instructions (hex hexadecimal):
Open the first relay: A0 01 01 A2
Turn off the first relay: A0 01 00 A1

Close the second relay: A0 02 00 A2
Open the third relay: A0 03 01 A4
Turn off the third relay: A0 03 00 A3
Open the fourth relay: A0 04 01 A5
Turn off the fourth relay: A0 04 00 A4"

Re: Serial MCU controlled relay/switch
Hi all
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.
Kind regards
Steve

Re: Serial MCU controlled relay/switch
This plugin will not work with any Sonoff T1. According to Tasmota wiki:countcobolt wrote: ↑17 Jun 2018, 16:13 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.
"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.

Download and try: v23
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.
Re: Serial MCU controlled relay/switch
You're right... i left out one index, and ESP did not honor buffer overflow.
![Lach :)](./images/smilies/icon_e_smile.gif)
Try the updated binary.

Re: Serial MCU controlled relay/switch
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.

Re: Serial MCU controlled relay/switch
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.
Re: Serial MCU controlled relay/switch
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
Re: Serial MCU controlled relay/switch
Will give it a go when I get home in an hour or so.enesbcs wrote: ↑05 Aug 2018, 09:52I see.

Re: Serial MCU controlled relay/switch
Can't get it to work. Relay still just turns on or off as if there are no rules.
Will have a play with the rules and see if I can get something working tho

Re: Serial MCU controlled relay/switch
Check v2:
Code: Select all
on lc#Relay0 do
if [lc#Relay0]>0
timerset,1,1
endif
endon
on Rules#Timer=1 do
relay,0,0
endon
Code: Select all
on lc#Relay0 do
timerset,1,1
endon
on Rules#Timer=1 do
if [lc#Relay0]>0
relay,0,0
endif
endon
Re: Serial MCU controlled relay/switch
Will give V2 and v3 a try and watch the logs.
I assume the rules don't need to be enabled anywhere else in the settings to enable them? Just enable rules in advance settings then create the rule for them to work.
Thanks for for assistance and patience so far.

Re: Serial MCU controlled relay/switch
Update.
Managed to get it working with your first code. Appears sleep and reading instructions correctly kinda help.
I had my device named Relay and say you had it name lc. A simple change in name fixed it.
Sorry for the stuff up my end.
Thanks heap in helping me out here.
Is it possible to reduce the time to less than 1 second? I will have a read and see if I can find the answer myself but just in case I fail again.
fyi all 3 rules work and give the desired result

Re: Serial MCU controlled relay/switch
Great news, you are welcome.
In rules one second is the smallest interval as i know.
I think i can implement a new command in the plugin for example "relaypulse" for smaller intervals, but due to the characteristics and speed of the serial connection the results will not be as you expect. I have an LCTech relay somewhere hidden in my shelf, will try it and publish the plugin if it can handle it.
Re: Serial MCU controlled relay/switch
Thanks for the offer but no need to worry if it isn't currently supported. This is just a test device I had laying around while I learnt the ropes. Have ordered some sonoff low voltage boards to use as the garage control runs off 24V DC and this test board is a 12v board so I will be using a power pack while I test.
Thanks again for your help. It was very much appreciated.

it is controlled by the standard LCTech serial commands (A0 01 01 A2...) which is supported by this P165 plugin. Also the onboard ESP-01 may require the 1MB Puya safe binary.

do int it at the moment via wget
but isn't there a option via esp module fhem?

Re: Serial MCU controlled relay/switch
How can you execute any ESPEasy command via fhem? You can use exactly the same way the relay command, mentioned at the first post of this thread. I am using relay command via HTTP and within RULES.
I am not familiar with FHEM, but with MQTT there are a third way:
Code: Select all
<MQTT subscribe template>/cmd with payload: <command>
Re: Serial MCU controlled relay/switch
thanks

Re: Serial MCU controlled relay/switch
As always, you can find the compiled binaries attached to the first post in this thread. Try the PUYA safe binary if you are not sure which one is for your ESP-01.

Re: Serial MCU controlled relay/switch
You are welcome. Maybe you can try faster serial speed, some device can be used at 115200 baud. Some can not.
![Lach :)](./images/smilies/icon_e_smile.gif)
Also disable command doubling if device works without it. Anyway, Wifi devices have some delays basically.

using latest firmware,

Could you make a version with Fhem enabled in controller list?
OpenHAB MQTT and FHEM would be perfect

Re: Serial MCU controlled relay/switch
Hello, I have LC Tech relay x2 12v, I followed post #138 on installing ESP Easy (ESPEasy_1M_128kSPIFFS_PUYA.zip)
Everything works, MQTT, HTTP, and I can hear the switch clicking when turning it on or off, but I am not getting any output voltage from both relays, what could be the cause? This is the second board I have bought already, the first one burned(https://www.aliexpress.com/item/12V-WIF ... 34092.html) and I dont want to order another one, any ideas? Thanks

Second thought: Check soldering points of the relays at the back side, resolder them if necessary - of course check NO/NC with a multimeter previously.
Re: Serial MCU controlled relay/switch
Is there a way to use this with the 4x channel LC Tech relay? Works on my 2ch version, but the only option in 'number of relays' is 1 or 2.
