Error reading filter status

[gtg465x]

The controls are working fine in HomeKit, but I didn't see any filter status indicators, so I looked in the Homebridge logs and found this being printed quite often.

Model: Airmega 400S
Node version: 10.16.0

[Homebridge] [2/20/2020, 4:42:17 PM] [Airmega] [ERROR] Unable to get filter change indication for Max2 Filter. Cannot read property 'lifeLevel' of undefined

Ditto. Otherwise, I really like the plug-in. Can anything be done?

[shamanskyh]

#12 should fix this issue FWIW

[paqpaqpaq]

same here. I don't see how #12 is a fix?

[zebzbranek]

I couldn't get it to work. I tried "npm install -g git+https://github.com/shamanskyh/homebridge-airmega.git” and with sudo. I will need to be spoon fed at this point. Would really like to get it working.

Hey @paqpaqpaq --
The reason this broke is that Coway changed the name of the filter that is reported from the API and the existing plugin (without #12) looks for the filter by its name. #12 looks up the filter status using an identifier that is hopefully more stable, meaning it's less likely to change, than a name.

Separately, Apple's Home app doesn't seem to indicate when a filter needs to be changed, even when a plugin/integration is working as expected and the filter status is readable in other apps that use the HomeKit framework like Eve or Home+. I've verified this by using Apple's HomeKit Accessory Simulator to simulate an air purifier accessory with a filter service, and setting the filter status to need a change. It's up to Apple whether they want to implement filter status reporting in their Home app or not; the Home app only implements a subset of the full HomeKit framework.

Despite that, there are apps that are able to read and and use the filter status in an automation, which I did. Filter running out, trigger an alarm. This always worked.

Any news on this fix?

Just waiting on @aschzero to take a look at the pull request. The alternative is to create a more maintained fork of my own, but I'm not really a Node developer by trade and I'd really prefer to contribute back to the original author's work if he's willing to take a look at the pull request.

The last commit was on Apr 24, 2019 so this repo is probably abandoned.

If I sudo npm install -g git+https://github.com/shamanskyh/homebridge-airmega.git
then I get this error in return:

@shamanskyh: Will you open issues on your fork? Also can you publish that as a NPM package, so we can install it easily?

[WJKramer]

Many months later. I am still having this issue. Any work being done?

[dpesetsky]

I would also appreciate an update that eliminates the filter errors. Or a way to stop homebridge from checking for them. Thank you!! @aschzero @shamanskyh

Maybe you could comment out lines 47 to 53 of homebridge-airmega/lib/Purifier.ts
