The DachsApp shows you the current operating data of your Dachs in a graphically clear format. This allows you to check at any time and from anywhere how much thermal and electrical energy the Dachs is generating. In addition, how high the CO2 savings are and in how many operating hours the next maintenance is due. You can also conveniently check the flow temperatures of the heating circuits, heating and buffer storage, as well as the number of starts. Note: If you are running a latest generation Dachs (Dachs 0.8, Dachs 2.9, Dachs 5.5 Gen2), then your Dachs is not compatible with this version of the DachsApp. We have developed the DachsPortal2 especially for the new generation: https://dachsconnect.senertec.com/ Always in control With the DachsApp, you can make changes to the settings of your Dachs (micro-CHP) system remotely at any time. For example, you can conveniently adjust the heating circuits on the go and adjust operation between day and night mode. Always at an advantage From Dachs operators for Dachs operators: the mobile application informs you about nationwide discounts and benefits. Whether exclusive discounts or special benefit packages. As a special feature, the app navigates you directly to the offers of the Dachs Fan Club. Here you can find attractive discounts nearby. You can find more information about the app at: https://www.senertec.de/dachsapp/. We welcome your feedback to dachsapp@senertec.com - we are always interested in improving the DachsApp and aligning it with the needs of our customers.

Verdict
The clearest difference is update cadence: 2G at every 2 months against my Dachs's every 10 months. On price, ads, in-app purchases and device support there is nothing between them.
