In some embodiments, low power wireless communications circuitry 214 may be a mesh network compatible module that does not require an access point or a router in order to communicate to devices in a network. Mesh network compatibility can include provisions that enable mesh network compatible modules to keep track of other nearby mesh network compatible modules so that data can be passed through neighboring modules. Mesh network compatibility is essentially the hallmark of the 802.15.4 protocol. In contrast, high power wireless communications circuitry 212 is not a mesh network compatible module and requires an access point or router in order to communicate to devices in a network. Thus, if a first device having circuitry 212 wants to communicate data to another device having circuitry 212, the first device has to communicate with the router, which then transmits the data to the second device. In some embodiments, circuitry 212 can be used to communicate directly with another device that has circuitry 212.
Non-volatile memory 216 can be any suitable permanent memory storage such as, for example, NAND Flash, a hard disk drive, NOR, ROM, or phase change memory. In one embodiment, non-volatile memory 216 can store audio clips that can be played back by speaker 218. The audio clips can include installation instructions or warnings in one or more languages. Speaker 218 can be any suitable speaker operable to playback sounds or audio files. Speaker 218 can include an amplifier (not shown).
