The aim of the Wireless Connectivity Software Development Kit (SDK) is to minimize the effort required on customer side to enable his host MCU to communicate with Würth Elektronik eiSos radio modules. It contains the implementation of all available commands in pure C-code. In order to integrate any Würth Elektronik eiSos wireless module, the user has to simply port the corresponding C-code to his host processor. This significantly reduces the time needed for developing the software interface to the radio module.
The "ACC V3" is a tool to update and configure certain Würth Elektronik eiSos modules. The supported features will include the search and upload of new firmwares as well as the modification of the available configuration parameters. It allows full user control over all supported products, as in the range of the producer’s intentions, always referring to the respective manual of the connected module.
Due to current export legal restrictions, we are required to control the provision of software. To download the software, please contact our technical support or your local sales representative directly. Thank you for your understanding.
User Application
Advantages for the Customers
- „Almost live“ data access on his currently use of resources including a “live” cost estimation instead of yearly billing
- Comparison on a day-by-day basis when data is available
- No costs for the manual readout, no huddle with a yearly appointment for manual meter readout person
- Secure due to encryption, only the owner of the data knows the key required for decrypting the messages of the meters
- Several metering providers can share a single Smart meter Gateway (water, gas, electricity, heat cost, …)
Disadvantages for the Customers
- High initial costs: Smart meter gateway and meters with wireless interface
- Battery lifetime requires exchanging devices each 7 - 10 years in case of battery operated devices – due to security reasons “just” changing the battery is often prevented
