Tuya-mqtt help

[Christopher_Hemmings]

the main topic looks like it is no longer being updated.

Step-by-Step guide for adding Tuya-bulbs, Wi-Fi smart LED (Smart Life app) to OH2 using tuya-mqtt.js by AgentK

Is there any way to ping the device and check if it is online or not ? I have id and key, but can’t find topic which would trigger such action EDIT: Needed to restart tuya mqtt server and send command “get-states” to “tuya/< ID >/command” topic

and these later ones are locked.

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

You can capture the traffic between the app and your tuya device and then use tuyadump to decode it:

Can someone help me with this.
I have a fan which everything else is working except for speed
But when i set DPS 3 to anything it defaults back with 6.
So setting DPS 3 to 1 sends back a state of 6.

Only on this ceiling fan, i have an arlec tower fan too. and DPS 3 works perfectly fine on that.

this is my debug dump

Hi Christopher,
are you sure the DPS 3 is correct? I have one Windclam Fan, and the DPS for the speed is DPS 62. Seems depending on the product you have. If you have an ikohs, check out the following page

DPS for Create IKOHS Fans

[Christopher_Hemmings]

Yes. DPS 62 for me does nothing
DPS 3 changes speed but the payload must be the incorrect format or something for my device. When I use the smart life app to change speed dps 3 state is what is updated.

I think it’s something in the tuya-mqtt code itself
