The W-Modbus app has arrived! Upgrade firmware for LumenRadio W-Modbus devices by connecting to and upgrading the LumenRadio Gateway in the network through the app. In the Network map you will find a system overview where you can see signal strength, edit names of wireless nodes as well as seeing the health of the RS485 bus including which Modbus RTU address that is connected to that wireless node. You can also connect to any node in the network and change their name (up to 20 characters). The W-Modbus app requires W-Modbus firmware 3.1.1 and above, which can be downloaded from the LumenRadio support webpage. Note that you need to install FW 3.1.1 or above on the gateway from the nRF connect app to enable the functionality. It is also required to have at least 3.0.0 or above on all nodes in the network. You will need to update all nodes individually if they are on version 2.2.3. This will be the last time this is required. All future updates can be done by either this app or from the nRF connect app.

Reduxi connects devices that use, produce or store larger amounts of electricity. It determines when it makes sense to use, produce or store just the right amount of electricity via utilising our AI Strategies. Reduxi Controller links solar power plants, energy storage systems, heat pumps, and electric chargers to the Reduxi system. It manages electricity production and consumption, adjusts power draw from the grid, and uses advanced algorithms to ensure cost-effective energy use and maximum self-sufficiency. Reduxi Gateway This extension of the Reduxi system converts RS485 serial signals into TCP/IP signals. It is used when the Reduxi Controller’s two RS485 inputs are insufficient or when the device’s distance makes cable connections impractical. Additionally, the Gateway can control third-party devices via two relay outputs, such as a heat pump using SmartGrid Ready (SG Ready) or an EVU contact. The Reduxi Converters capture billing measurement data from meters with specific outputs without the need of additional power. The P1 and P1 – WiFi model wirelessly connects meters like the Iskraemeco AM550 to your network via WiFi or cable. The I1 (M-Bus) – Cable model connects meters like the Landis+Gyr E350 and E450 to the Reduxi controller via a wired connection. We optimize: Reduxi connects devices that use, produce or store larger amounts of electricity. It determines when it makes sense to use, produce or store just the right amount of electricity via utilising our AI Strategies. Smart EV Charging: When you at your home or in work, your vehicle could and should be charged the way it gets the battery full for the lowest cost possible. This becomes even more important if your company owns and charges multiple vehicles. Demand Response: When there is too much electricity available on the market, the result in low or even negative energy prices. You can benefit by adapting your use or production of energy to match what the market needs: use less or more, depending on the time. Supported devices: Reduxi can connect to more than 250 devices across 50 brands.
