Different LED strings seem to be using different commands. I need to figure out which LED string uses which command.
Anyone experiencing this issue can help me fix this by doing a CLI install of this Homey app version which contains extra debug logging, This should tell me what is going on. Just run this version from command line and first control the Twinkly with the smartphone app than try to control the Twinkly with my Homey app. The logging should show the status your Twinkly is in (something like off, effect or movie).
Please report your findings here.
