Generic Matter RVC with Switchbot K11+ in 2.4.4

sidjohn1 · February 13, 2026, 5:04pm

While not officially supported... yet, the Switchbot K11+ does work with the new Generic Matter RVC driver.

Set Clean Mode:
0 - Quick
1 - Auto
2 - Deep clean
3 - Quiet
4 - Max Vac

This maybe expected behavior for an unsupported device, but it is generating an error on line 167 of the driver.

java.lang.IllegalArgumentException: Text must not be null or empty on line 167 (method parse)

That error is from missing supportedCleanModes..

Either completely missing or maybe the initial reports came out of order..

Can you screenshot the "Current States" section of the driver page?

The following are from a different driver I was playing with before the Matter RVC driver came out.
Number Of Buttons
Supported Button Values
Pushed

Setting clean modes does seam to work, at least it shows up as changed in HA and the app when done from HE.

Yea.. It's missing the supportedCleanModes..

Try hitting configure again (using the Generic Matter RVC driver) ..

sidjohn1 · February 13, 2026, 6:08pm

boom! Second configure is the charm?

bcopeland · February 13, 2026, 6:10pm

Nice.. Any chance I could get you to give me the fingerprint for this device?

If you switch the driver to "Device" and click Get Info it will spit out a fingerprint in the log..

If you could copy/paste the text here I can add it to the driver so the next person with that device will detect properly..

fingerprint endpointId:"01", inClusters:"0003,001D,0054,0055,0061,0150", outClusters:"", model:"K11+", manufacturer:"SwitchBot", controllerType:"MAT"

Thanks

I have a Dreame X50 master and it seems to work with the driver but i do see this error?

bcopeland · February 21, 2026, 11:37pm

Hit configure .. It's missing some state variables that it gets from initial polling..

BorrisTheCat · February 22, 2026, 10:31am

same.

What is that line looking for?

bcopeland · February 22, 2026, 12:35pm

That line assumes "supportedCleanModes" is populated..

BorrisTheCat · February 23, 2026, 10:54pm

so that seems to be blank as a option

bcopeland · February 23, 2026, 11:41pm

Strange... Can you enable debug logging and then hit configure again and put the log here please?

BorrisTheCat · February 24, 2026, 10:20pm

I have hit config multiple times but now with debug on this filled in straight away

bcopeland · February 24, 2026, 10:25pm

Ok.. It reported it that time..

Weird..

SupportedCleanModes is populated now.. So you shouldn't get that error anymore..

BorrisTheCat · February 24, 2026, 10:27pm

is there a bug in the code that it only populates if debug is on?

bcopeland · February 24, 2026, 10:32pm

Nope.. It processes any time it receives that report.. I'm guessing either the request or the report was getting lost..
