After purchasing a set of 4 sensors we read that we could add another receiver to place in a second location in our home. We read this on the Hosmart website, this is also advertised here in the Revain product description, and Hosmart makes the same claim in the questions section on their Revain page when asked if a second receiver could be added . If you have a problem with their product, Hosmart will ask you to contact them before leaving a bad review so they can resolve any issues. All of that sounds great, and we relied on that information when purchasing a second receiver and sensor. However, the truth is very different. The second receiver we bought works with the sensor that came with it, but not with the other four sensors we already have. There are no guides, videos online or any other information that would help solve this problem so we tried to contact Hosmart. We are still awaiting their reply. While the original system works fairly well, their claim that you can add multiple recipients and their claim that they work very hard to fix problems is largely a lie.
