I’ve a roborock s5 max. There is a custom (CLI) app that works with my S5 max. The first app the zone cleaning and target point didn’t work. But cleaning/ status and fan speed was working. A few weeks ago someone else made a update. The Zone cleaning and target point is working now, but fan speed didn’t work anymore (I hear the beep, but it is changing always to balanced). Where can I find the document for this device (I don’t know where to look)? So I can see where there is made a change. I’m not a programmer, but seeing what is changed can help me to find the solution. #1: [https://github.com/Maxmudjon/com.xiaomi-miio/files/4915546/com.xiaomi.roborock.zip](https://github.com/Maxmudjon/com.xiaomi-miio/files/4915546/com.xiaomi.roborock.zip) #2 [https://github.com/Maxmudjon/com.xiaomi-miio/files/6408030/Roborock\_Zones\_Goto.zip](https://github.com/Maxmudjon/com.xiaomi-miio/files/6408030/Roborock_Zones_Goto.zip) ---

With file comparison software, often called ‘diff’, you can compare similar files of different versions, any change between them is marked. [https://duckduckgo.com/?q=diff+software&ia=web](https://duckduckgo.com/?q=diff+software&ia=web) If the filedates are still intact, start with the most recent files I would say. ---

I didn’t make this app. A few guys with the same issue on GitHub has made it. Unfortunately I can’t program this things. But looking for some change is something I can do. So tonight I’m going to try it. ---

I’ve found the code line with the change. And it works (with zone cleaning) Only this wasn’t the problem. so looking for another problem 😂 But couldn’t find the way to use fan speed for a roborock. ---

For everybody who needs it. There is someone on Github that have made a new version for the s5max vacuum. With fan speed / water level and room cleaning. > > > I've just recently gotten my xiaomi roborock s5 Max (new model) and when I use t…he token and ip to connect to the device with the MI home homey app I get the following message: "device.getState is not a function"
