Get works but set doesn't about tuyapi

[codetheweb]

get() works but set() fails if the key parameter is incorrect. Can you please try setting up your device again to regenerate the key?

[ckdarby]

@codetheweb Are there instructions on generating the key?

I tried using tuya-cli link-wizard but nothing would pair with it when my lights were blinking.

[codetheweb]

Other users have also reported issues with the link wizard, and I'm trying to track down the bug (although it works flawlessly for me).

You can view the old setup instructions here.

Just for reference sake for anyone else who stumbles across this, the lighs I have an issue using the wizard with is: LUMIMAN LM530

[codetheweb]

@ckdarby did your device work with the old setup instructions?

[ckdarby]

@codetheweb Have not attempted yet looked like a bunch of work but I have at least installed the Android app to capture packets.

[ckdarby]

@codetheweb Did not work. Got some pcap but nothing that looked usable with a key or keyId, etc.

@ckdarby , late response. Just connect to the device using the Tuuapi and use your alexa/phone app/whatever to set parameters. See what dps values change and set those sequentially.

Any update on this. I am also having issues with Merkury bulbs and plugs which I cannot set via this API. The set method times out.

@ankurp does get() work? Can you please provide a link to where you bought your device?

@codetheweb Thanks for your work on this module. This is the bulb I bought https://www.walmart.com/ip/Merkury-Innovations-Color-Smart-A21-Light-Bulb-75W-Equivalent-No-Hub-Required/254063201
They are cheap smart bulbs but I want them to get to work with HomeKit so I need to code up a plugin for a HomeKit bridge. I cannot get the set to work and I noticed the implementation in this actually works.

@ankurp do you mean that drumfreak's plugin works as expected for your bulbs, or are you pointing out that they implemented color controls?

If it's the first, then you're probably setting the wrong property on your device. Try starting Homebridge with DEBUG=* homebridge to see what properties drumfreak's plugin is changing.

Hi,

I am discovering your library since a few days and I am getting lost with the way I have to use to communicate with my light bulbs.

I have a similar problem than described here: I can get data but I cannot set them.

I got the keys by reading the logs from my smartphone ("adb shell" and "logcat" while navigating in Tuya Smart app). But it seems that the keys are not correct (maybe I use the bad value?)

So, the more I read this topic, the more I think that I have not the good key to change values on my light bulbs. Here is my question: how can I get the real generated key by Tuya?

As far as I understand, those keys are generated when the devices are linked to an application. I tried to create one on Tuya's website to use the app key and secret with tuya-link but they are valid for only 1 month (or I have to pay 1500$ to publish a smartphone app that I will not use!)

Thanks for your help :)

@christophermh44 did you try the method given here to obtain the key pairs?

@christophermh44 did you try the method given here to obtain the key pairs?

Yes, but I got errors while trying to get ids.

By the way, I finally succeed to get my device ids by looking into files inside /data/data/com.tuya.smartlife/shared_prefs/*.xml

[codetheweb]

Glad you got it working @christophermh44.

Closing this as the common problem appears to be an incorrect key parameter.
