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.
Hi, I already read the description and checked Wolf GMBH BWL-1S heatpump. I have a suggestion.
May we use it's LAN/WLAN interface to control it. This may be easier.
Please contact me and discuss it.
I have vast experience in Industrial Automation projects and have implemented various protocol converters based on MODBUS. I have designed a large number of products on MODBUS RS232/RS485 and MODBUS TCP.
Recently I have also designed a microcontroller based Heat Pump controller., but not worked on E-BUS.
Currently I am also designing an IoT system for HVAC control
Please let me know the details of your project
Thanks
I definitely be able to be of assistance to you in this project.
Hi
I work in a R&D center creating modbus ,eip, profibus comm modules for our industrial control products . I have in depth knowledge of implementing and enhancing modbus stack. I can do this for you. Though I will not be able to supply you any hardware , I will write the code and give you detailed documentation on how to implement the solution.
Thanks
