As electronics and appliances in the home continue to evolve, wireless networks that can monitor and control these are becoming more prevalent. Development platforms for technologies like RF4CE and ZigBee are becoming more available but can still be costly for a complete platform that supports interoperable devices with public ZigBee profiles. This paper details the design and implementation of a ZigBee Home Automation network using free tools on a low cost ZigBee development platform. The platform utilizes a dedicated processor for the ZigBee stack with SPI, UART, and USB interface, allowing the application code that was developed to be integrated into a wide variety of environments. / text

To gain empirical evidence of the nature of major household appliances’ performance failures, and of how dissatisfied consumers cognitively appraise product failure and their subsequent experiences in handling the negative event, the study explored by means of a survey the experiences of 200 female consumers in Gaborone, who had experienced dissatisfaction with any major household appliance within a prior four-year recall period. A convenience sampling technique was employed where pre-screened respondents completed a self-administered questionnaire. The results of the study show that respondents clearly differentiated their expectations concerning the functional and symbolic performance dimensions of their specific appliances. When linking the theory on perceived quality and expectancy disconfirmation, it was discovered that respondents’ expectations were disconfirmed due to the performance failure of their specific appliances. The performance failure was perceived in three distinct ways: functional performance failure, symbolic performance failure, and the combined functional and symbolic performance failure, rather than the usual, formal functional performance failure only. Very to extreme dissatisfaction were experienced and the product failure was appraised as stressful, leading to respondents feeling very to extremely stressed. The female respondents attributed blame for the poor performance of their major household appliance more to external sources like retailers/manufacturers than they internalised blame to themselves, the appliance or other people. They also believed that the party they held responsible for the poor performance could have prevented the problem. Due to the performance failure of their specific appliances, the respondents experienced various emotional responses (e.g. anger, shame, guilt, surprise, sadness and frustration) and of varying intensities. Significantly, more respondents felt very to extremely angry, sad, surprised or frustrated. Respondents did not experience high levels of shame and guilt. These emotions necessitated some coping strategies in the form of complaint actions. Respondents who felt very to extremely angry took formal complaint action (i.e. contacted the retailer to obtain redress). Respondents who experienced frustration significantly engaged more in problem-focused coping. Predominantly, female respondents engaged in problem-focused coping strategies that were confrontational and were aimed at external sources like retailers/manufacturers. Blame for the performance failure of appliances was directed more to retailers/manufacturers than to any other party like the self, other people or the appliance. Hence, a significant difference existed between the various coping strategies and attributing blame to the retailer/manufacturer, where respondents engaged more in problem-focused coping, than in any other coping strategies like emotion-focused or avoidance coping. These findings have both salient and practical implications especially in Botswana contenxt, which were pointed out to the retailers/manufacturers, educators, consumer protection organisations, policy makers and consumer scientists, to help consumers to function well in the marketplace. / Dissertation (MSc)--University of Pretoria, 2010. / Consumer Science / unrestricted
