Steps to reproduce

1. Unplug router from WAN
2. Restart home assistant
3. See unavailable devices

Additional information

Thanks, @jondycz for reporting this. I have been facing the same issue a couple of times. I am waiting eagerly for the solution, as my involvement here is meant to be run in the offline environment most of the time.

I am also having this issue. Have you ever figured it out? @jondycz

[Nealium]

I had this issue at 3am! I couldn't shut off the lights! I thought "well, this defeats the entire purpose!"

If you look at my pull's commits you can hotfix it yourself. It's not a big change at all.
The files are located in config/custom_components/localtuya, you can reach it with the normal File Editor add-on.

Note: you must restart your entire HomeAssitant instance for the code change to take effect.. or, so it seems.

I'm currently using v5.2.1 and still appear to be having this issue.
