[ERROR] Unable to get current state. Cannot read properties of undefined (reading 'prodStatus')

[cjtylr]

Hey there,

In the last 18 hours, my Airmega units stopped responding in the Home app. Went to Homebridge and saw a few errors:

• [ERROR] Unable to get current state. Cannot read properties of undefined (reading 'prodStatus')
• [ERROR] Unable to get current state. TypeError: Cannot read properties of undefined (reading 'prodStatus')

I've tried a few things, none of which have worked:

1. Reverting to an earlier version (3.4.0 and 3.3.2)
2. Uninstalling/re-installing the plugin
3. Changing my Coway password

Any thoughts? Thanks!

Apparently Coway changed their entire API today. I'll be looking at it ASAP.

Thank you!

Just checking on the status of this. I just re-enabled my AirMega plugin as a child bridge in HB and was wondering if this was causing the continued 'prodStatus' issues? Or is it still a Coway API thing?

[ohmantics]

I'm working on it still. Yes, the entire Coway API did change and this plugin needs to be revamped to the new API.

I found another homebridge plugin that seems to use the new API but not working for my Airmega 250S. Don't know if it will help you to update the plugin. I am not a tech person so I cannot really tell how much work need to be implemented. Thank you and looking for the update! https://github.com/OrigamiDream/homebridge-coway

I have this problem as well. Tried the plugin linked by @chuuya33 and did not work for my 250S either. I'm not a dev but let me know any way I can help here!

I spent some time this weekend modifying the plugin found by @chuuya33 to support my Airmega 300S. I've updated my fork (main branch) if anyone would like to try it out https://github.com/shamanskyh/homebridge-coway.

I attempted to modify this plugin a bit, but didn't get very far, and the other plugin seemed a bit more straightforward to me. I very much appreciate all the effort that's gone into developing this plugin, though, and hope that this is useful if folks want to take it further/edit things.

Some caveats:

• I am not a Typescript developer by trade and there are probably places where my code could be significantly cleaner
• I have only tested this with an Airmega 300S purifier, and I have not done any testing with the Marvel air purifier or Driver water purifier that the plugin supported previously
• There were some items in the original plugin that I found either confusing or unnecessary and modified them. These include:
  • Reducing a 5 second refresh/fetch interval down to a 30 second refresh/fetch interval
  • Removing the code that prevents duplicate requests from being sent (this wasn't working for me early on, and I found it easier to remove)
• I based my accessory on the Marvel air purifier code, and adjusted things along the way. I wasn't able to add some of the potential improvements back to the Marvel and Driver files -- I wanted to leave these as clean and unmodified as possible, though I realize that I may have broken things with changes to the platform-level files.

So anyway, I hope someone finds this helpful. I'm fairly busy at the moment and I can't really provide technical support if you want to try it out (or need assistance installing it), but this has been working for me so far. Very open to feedback if others want to leave it on my fork.
