Addresses for WO1C

[leifnel]

You have the pdf with addresses for HO1A
Do you have, or know where to find addresses for WO1C (Air-to-water heatpump)?

[mqu]

hello, I don't know just now. I am going to seek around.

you can have a look at this table : https://openv.wikispaces.com/Adressen ; your device is in the first column. The device ID is 204D.

there is an other table here mapping device products and device ID : https://openv.wikispaces.com/Ger%C3%A4te

your device is supporting P300 protocol. This is a good news. With vitalk raw commands, we can support any addresses and commands.

Do you have an infrared connexion working ?

• I have added PDF documentation for WO1C device : https://github.com/mqu/viessmann-mqtt/tree/master/docs
• I am planning to make a more configurable application with device specification in etc/device.yaml.
• I have much of work to do now ...

I have the infrared connection working,
If it is possible, I'll use node-red and vitalk raw to adjust the warm water temperature up when the sun is shining and my photovoltaic's is producing power.

thank you for your reply.So you just have to clone my vitalk project and build it. Documentation for your device is here.

WIP : hello Leifnel,

I'm now able to read and write values to Viessmann device, based on YAML description file. Code is located here : https://github.com/mqu/viessmann-mqtt/tree/master/src/wip

you can now duplicate description file for any device and describe commands. There is still some work to do but task is filled at about 85-90%.
