Hardware

Meteobridge can be used with two miniature consumer routers from TP-LINK and one from ASUS. These devices are converted into a Meteobridge by flashing a new firmware. As always when you flash un-official firmware to a device you are voiding the manufacturers warranty. That means, when the device gets faulty later on, you can't reach out to TP-LINK or ASUS for warranty. smartbedded UG, whichs owns the Meteobridge software does also not provide any warranty on the flashed device. As the routers are very cheap and risk of bricking the device is minimal, you don't have a significant financial expousre. However, you have to know, that you are converting the router into a Meteobridge at your own risk.
