We use Linux and prefer open source. We need everything from RS485 control of heat pumps to organization of all company operations.
| Create a software environment for new company | 
|  | Linux is mandatory, open source is preferred. Design the complete software environment for a new, fast growing company.
Purchasing, accounting, sales, customer management. | 
| Software for heat pumps with RS485 interface | 
|  | You work directly with the hardware, 3 air heat pumps with RS-485 interface. During operation, the software creates a performance map of the heat pumps used. | 
| Software for marketing own electricity on the spot market | 
|  | The software must read weather forecasts, solar yield forecasts, and spot market prices and develop an optimal strategy to best manage the home's resources. | 
| Dynamic simulations for extreme loads on the house | 
|  | The statics for the house is probably easily done, but we also want dynamic simulations of extreme events. Something like the crash tests for cars, but only virtual. |
