Hardware

Meteobridge can be used with a variety of miniature consumer routers from TP-LINK, one from D-Link and one from ASUS, or you can by a Meteobridge PRO which comes on dedicated hardware. The devices from TP-Lin, D-Link and Asus 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, D-Link or ASUS for warranty. smartbedded UG, which owns the Meteobridge software, does also not provide any warranty on flashed device. As the routers are very cheap and risk of bricking the device is minimal, you don't have a significant financial exposure. However, you have to know, that you are converting the router into a Meteobridge at your own risk. If you don't want to take the risk, please buy a ready-made Meteobridge solution from one of the resellers or you go with a Meteobridge PRO.
