Smartlife/Tuya switches via MQTT

[Andreas3 (Andreas)]

Hi

I have problems to connect my smartlife/tuya simpleswitch to openhab.

I have been reading a lot on this community and other webpages, but I still can’t figure out how to connet my smartlife via mqtt broker.
As I understands it, I don’t have to flash it with tasmota.
I don’t need to connect my switches to mosquitto.
I just need to add generic mqtt thing from openhab (as client) and use my mqtt broker “as a bridge” to my switch (client).

I’m running openhab 3 on ubuntu and mosquitto on my Synology NAS. I have my smartlife switch ID, localkey, local IP.

Openhab has 192.168.1.5 and my mqtt broker is online, generic mqtt is online with bridge.
Synology nas runnig mosqutitto has 192.168.1.160

I have tried generic mqtt, add channel, on/off switch, mqtt state topic / command

Configuration:

tuya or no text/simpleswitch or switch or no text/#id# bffea3d1258b5fa68xxxxx/#key# 19d1038606axxxx/#IP# 192.168.1.215 or no text/topic
tuya or no text/simpleswitch or switch or nothing/#id# bffea3d1258b5fa68xxxxx/#key# 19d1038606axxxx/#IP# 192.168.1.215 or no text/command

What have I been doing wrong.
Do I need to put id, local key in a file with somewhere (in mosquitto or openhab)?

Thanks

But you will need your switch to connect to the broker, so I’m not sure what you mean by

@Andreas3

I don’t need to connect my switches to mosquitto.

I thing that is one off my issues. I can’t figure out how to add my switches to the broker

You don’t. It’s the switches that need to able to run MQTT and need configuring to talk to the broker.
but
They cannot do that without reflashing.
so
This post, which you must have seen, tells you how to use Tuya app and an extra script to act as intermediary between Tuya switch and MQTT. The script is the thing that needs configuring to talk to your broker.

Tuya devices to Openhab via MQTT - a working solution (without flashing)!

Dear OH-community, I found several postings about adding tuya devices to OH. Thanks to @tsightler finally there is a working solution now. Tom rewrote his whole code with some modifications on the underlaying TuyAPI. One of the highlights here is the easy naming (device names instead id’s) and the OH-friendly path (for example: if you have a power strip with multiple outlets, you can access the mqtt-topic easily by tuya/powerstrip/dps/2/state). Please note that the underlaying TuyAPI doesn’t …

I have probably misunderstood some info long then line.

Yes I have read that post. I will go through it again, closely, and test again. Then comeback

Thanks for your support !

Note : Tuya no longer supports this for accounts created after March 24, 2021. If you created your cloud account after that date, this method will not work.

Neither you need to setup the script that talks between tuya and MQTT.

I would advise getting that working first before even looking at openHAB.

https://github.com/codetheweb/tuyapi/blob/master/docs/SETUP.md

I always work from device to openHAB and you can verify it working in MQTT using another client like MQTT Explorer.

Learn how the device is controlled through a MQTT client before adding it to openHAB.

Thank you for your time

let see, I hope I have made some small steps forward

I have got my local key, ID and name from iot.tuya.com
