The plugin is already returning TANK_LEVEL information to Homebridge. The HomeKit spec supports WaterLevel but I am not aware of a separate tank full characteristic.

Midea does have a TANK_FULL attribute which I currently ignore... as I assumed that if this was set, then TANK_LEVEL would be 100%. If there are cases when TANK_FULL could be set, when level is less than 100% then the only way to report this to HomeKit would be to override what Midea is reporting as TANK_LEVEL and set the HomeKit water level to 100%.

[simplytoast1]

Interesting.... I don't see water level in HK so I might be missing something. Because I can create an automation if rather level is 100% but I'm not seeing that exposed.

[dkerr64]

On my Apple Home app... open the dehumidifier, select settings gear icon, and immediately under the name it reports "Water Level 0%" in my case it will always be zero because I have hosepipe directly to a drain. I do not know how you access that for an automation, but it is exposed to Apple Home app.

[simplytoast1]

Weird... it doesn't not for me

My (macOS version) screenshot below. What do you see if you click on the two accessories?

[simplytoast1]

The temperature sensor and the dehumidifier - and in that sub accessory there is no water level.

[simplytoast1]

Interestingly enough, on MacOS I see it. Let's chalk it up to an iOS issue. The only issue is I am unable to do an automation off of it.

[dkerr64]

my iOS version looks just like the macOS one above with water level and fan speed. Is your iOS version 17.4 or older? These things can change with iOS version.

[simplytoast1]

I had to reboot the iPhone to see the water level. So now it shows properly. Still unable to do an automation off water level but that may be a HK restriction hence the request to add a sensor if water level = 100% to close a contact sensor

[kovapatrik]

a leak detection sensor could be better for this - although it does the same as a contact sensor, I feel it's more in the context of the dehumidifier

[dkerr64]

Ah, ok, so that is an idea... add a contact or leak sensor device. That might be doable.

[simplytoast1]

I would warn about a leak sensor as it will set off alarms on a HomePod (and other devices) as a high priority. I would give an option. I just want to do an automation if the bucket is full. Some may want an alarm.

[kovapatrik]

ah I didn't know about that functionality

[kovapatrik]

midea dehumidifiers have a property called TANK_FULL, should I use this property, or use the water level and the user could set the level percentage when they want to trigger the sensor?

[simplytoast1]

If you have TANK_FULL I would use that

[dkerr64]

I have a feeling that TANK_LEVEL is probably not that accurate so if there is a TANK_FULL attribute reported that is probably best. Mine is connected to a drain so I never see any values, but would be worth testing and monitoring what is returned.

[kovapatrik]

this is now released with v1.0.2. Thanks to @simplytoast1 for the tests!

[simplytoast1]

Seems the contact sensor still isn't closing despite the bin being full. Weird that it worked in my test environment but not production.

[kovapatrik]

Hmm, so the problem is that the sensor isn't triggered when the tank is actually full? Can you please restart your child bridge or Homebridge itself and look for any suspicious logs like Error: Cannot add a Service with the same UUID?

[simplytoast1]

There was on a prior version but this child bridge starts up error free. I can remove the Dehumidifier and re-add to make everything clean if you would like.

[kovapatrik]

Yes, please do that! Also, don't forget to remove the cached accessory.

[simplytoast1]

After removing and clearing the coaches accessories the sensor is still not changing state although being reported in the logs of water level being full

[kovapatrik]

I've changed the logic for TANK_FULL in 1.0.4. Could you please test it? If it still not works, could you please turn on debug mode again, open the Home app and then send me the logs? When you open the Home app, all property will get logged so we can see what the accessory thinks the TANK_FULL value is.

[kovapatrik]

Should be solved in v1.0.5. Again, thanks for the tests @simplytoast1!
