I am wondering if I could be able to control the ventilation system in my house through Homey.
It can be externally controlled through the modbus-protocol (english instructions starts at page 12): https://www.flexit.no/globalassets/catalog/documents/111398_fdv_117989.pdf
Here are the instructions that I would be able to use: https://www.flexit.no/globalassets/catalog/documents/111400_modbus_nordic_basic.xlsx
The question is, will I be able to use Modbus in Homey? What kind of Modbus RTU should I use? Assuming that TCP/IP is the way to go? Are there Modbus integrations vs homey that could be reused?
Assuming that I would have to write an app to support the RTU?
Grateful for all help and support.
