Buderus KM100 can't connect

[scholli113]

HI,

I have a Buderus KM100, as I understand Nefit would be the protocol that should work but what ever I try I can't seem to looking. I tried Variations for logging in.

I tried like this

"accessories": [
{
"accessory": "NefitEasy",
"name": "thermostaat",
"options": {
"serialNumber": "XXX XXX XXX",
"accessKey": "XXX-XXX-XXX-XXX",
"password": "Bosch ID PW also tried Device PW"
}
}
],

I tried like this

"accessories": [
{
"accessory": "NefitEasy",
"name": "thermostaat",
"options": {
"serialNumber": "XXXXXXXXX",
"accessKey": "XXXXXXXXXXXX",
"password": "Bosch ID PW also tried Device PW"
}
}
],

Would be great If somebody can give me some ideas what to do here

Which error are you receiving, specifically? I can't remember if the KM100 uses the same protocol as the Easy.

I get this message

Its hard for me to understand how the set serial, Accesskey, and password

Or if KM100 is supported at all

[robertklep]

XMPP authentication relies on the serial number and access key, not the password.

For Nefit, the serial number consists of 9 digits and the access key of 16 characters (without any hyphens, -, in between), and is also case-sensitive (so a lower case "a" is not considered to be the same as an upper case "A").

Both values can be found on the packaging of the device, and/or on the device itself.

I also don't know if the KM100 is supported, at least by the Nefit Easy driver. There's also a more generic module, bosch-xmpp which (I believe) does support it, but there's no HomeBridge support for it.

Okay I guess it doesn't to I get this correct for bosch-xmpp I would need to setup home assistant which I then can connect to HomeKit
