Is there already sombody who looked at een Homey App for De’Longhi coffee machines with bluetooth connection? If not than it will be my first try to make an app 
I tried searching on the forum but didn’t find anything with the name de’longhi or delonghi
Then it isn’t there 
At the moment i made the app work and connecting to the machine using bluetooth BLE. So far so good. But i can’t seem to find anything on the capabilities. Is there sombody that has example code for turning on and of a bluetooth device with a homey app?
You could take a peek here GitHub - nklerk/nl.nielsdeklerk.XiaomiYeelightCandela: Homey App for Xiaomi Yeelight Candela BLE Lights.
BLE doesn’t have a generic way of turning devices on or off. A BLE device might implement a certain well-known profile (for instance “health care” or “sports and fitness”), but it’s not a requirement. In my experience, a lot of manufacturers use their own (usually undocumented) way of controlling a device over BLE. So knowing how to switch a light will very likely not help you finding out how to switch a coffee machine.
I understand, but looking at some example code makes a lot more sense than all the examples on the https://www.bluetooth.com website. My De’longhi android app is able to switch on the machine. So i think it should be possible. Maybe i’m wrong but lets try 
managed to find a solution? I would also like to take advantage
Unfortunately lacking the time. Connecting is no problem but as @robertklep stated. It’s looking for a needle in a haystack. Spring is comming so, automating my garden has more priority. Who knows I’ll find the time next autumn.
I would be interested i an app for DeLonghi WLAN coffee makers like Primadonna. I could create an app but don’t know about an (official?) API.
Maybe you can use a BlueTooth sniffer to find the commands:
