Hi , many thanks for the great program. I have been using it for a while now and started last year to implement a binding for openhab home automation based on your project. You can find more details here http://knx-user-forum.de/openhab/41186-neues-stiebel-eltron-waermepumpen-binding.html and https://github.com/openhab/openhab/pull/2101 The complete decoding of the different request are described in and xml file - > https://github.com/kreutpet/openhab/blob/master/bundles/binding/org.openhab.binding.stiebelheatpump/src/main/resources/2.06.xml When decoding the current value request with a serial sniffer a saw also other values which are currently missing in the decoding definition. I was wondering if somebody already find any details on decoding the following infos from the original stiebel software. Here the info i see on the screen of the original stiebel software. Here a screenshot of the dialog showing the info->https://drive.google.com/file/d/0B76ZUH63aPGQRl9RTzhMZHNtc2c/view?usp=sharing Status messages 1. compressor defrost 2. Power enabled 3. HP limiter 4. LP limiter 5. Anode 6. Stove/fireplace operation Outputs 1. Heat stage 1 2. Heat stage 2 3. Heat stage 3 4. Compressor A 5. Heat pipe valve 6. Mixer open 7. Mixer close 8. Diverter valve 9. Heating circuit pum 10 DHW circulation pump How can I decode above information from below reponse of the heat pump? This is the response of my lwz 303i version 2.06: 01 00 48 fb 01 aa 00 72 01 3a 00 a2 02 dc 01 ce 00 00 00 00 00 59 01 73 11 18 27 27 f4 ca 0c 22 1d 00 00 57 00 00 00 00 00 00 00 01 00 10 03 based in this response "Compressor A" and "Heating circuit pump" are the only active (true) info i see. All other are deactiveated The the following decoding rules i can successfully decode the current values. Many thanks Peter
