Geysers are an essential home appliance especially during the winters. However, many wish that they don’t have to get up early in the morning to switch it on, to ensure hot water is there when they need to rush to work. One way to deal with this is to plug the geyser on a smart plug which is linked to a smart speaker, say an Amazon Echo Dot. This will allow users to turn on or off the geyser with voice commands. But if you don’t want to use a smart plug then opting for water heaters and geysers with voice support or Wi-Fi remote are the only options. Here are some deals as part of Amazon Great Indian Festival sale on smart geysers and water heaters.
