Simple Modbus i E-BUS integration...or maybe something more...

As a HVAC company we have an issue to solve - it involves an integration between Modbus devices and E-BUS device. Here's what we know: Modbus device is in my opinion well documented (it's an OJ Electronics WLM-3 Master Module + some thermostats and humidity sensors) so we know all the instrucions. On the other hand we have an E-BUS device ( Wolf GMBH BWL-1S heatpump) with absoltuely no documentation about E-BUS communication. The task is simple like and looks like this: 1. You supply all the electronics needed. 2. You discover commands being transmitted over E-BUS causing following actions on heatpump unit: - swtiching between heating/cooling mode - setting desired supply water temperature 3. You write a code which translates commands from Modbus to E-BUS (ie. "switch the HVAC system to cooling") I can take part in sniffing e-bus protocol, connecting equipment on-site and so on, but i'm not a coder at all. I'm not an electronic either but I have basic knowledge about that which maybe useful if you'll be working remotely. If you are skilled professional I'll have more projects about integrating different HVAC appliances. I was thinking about using [login to view URL] or something similar to create our own, branded HVAC control center. I'm looking for someone serious, prefferably VAT payer, as VAT invoice is most wanted form of cooperation between us.
