See your hybrid solar inverter and home battery directly on your own network, without a cloud account in the middle. The link is a wired RS485 connection to the inverter's COM port through a small RS485-to-Ethernet gateway, so live solar production, battery charge level and power, and inverter temperature land on a device tile and in the Energy dashboard, while a running energy total keeps building across restarts.
That wired gateway is what the app needs to work: a model that translates Modbus TCP to RTU, given a fixed address on the same network as Homey, with no other controller talking to the inverter at the same time — Homey has to be the only master on the RS485 bus. From there, flow cards react to a low battery or a burst of solar production, and Homey can control the inverter and battery as well: charging, discharging, work mode and reserve, and following day-ahead prices. It never acts on the inverter on its own — everything happens through the flows you build or the optional price optimiser you enable.
