Betty: The Super Power to Save Power

Electricity bills form a major part of office and household running costs. For organisations, average electricity consumption accounts for 19 per cent of the running expenditure.

Traditionally, in India meter readings are taken manually, which quite often end up as ‘round-off’ or ‘approximate’ figures. Moreover, users do not get to see exactly how they are spending on their electricity and thus figure out ways to lower the bills.

Thankfully, the smart age of connected devices has given us ample new options that inform us about our energy usage and ways to lower it. One such option is Betty by Beyond Evolution, which merits attention due to its affordable price.

The inception

Betty—The energy monitoring and security plug

Saurabh Sharma, co-founder and CEO of Beyond Evolution, saw the opportunity in controlling the power consumption of everyday appliances and easing the burden of electricity cost for the common man. Quite often users forget to switch off electrical appliances during power cuts, leaving the appliances running when the power resumes. This not only wastes power but also poses fire risk.

“Our intent was not to become a so-called ‘home-automation’ solution provider. Betty has been designed for the more common challenges faced by majority of the people. Home automation may indicate a form of luxury, while Betty targets to address the day-to-day necessities,” explains Sharma.

The whole thought process kick-started R&D initiatives, which took 18 months to develop the complete solution. Betty can in-situ measure appliance energy consumption, set auto-control (automatic ‘on’ and ‘off’) schedules as well as electricity usage thresholds, provide energy usage analytics, and, more interestingly, notify users of any security breach.

Being a newcomer in the manufacturing arena, the company had to scale a steep learning curve. Limited funds were another challenge. To start the fund inflow, the company kicked off with mobile application development and attracted significant customers. Once the production seemed financially feasible, they started off with the Betty project. Expensive components added to the trouble. Getting a fair deal from mould providers and coming up with mould designs was also not easy.

Betty is a GSM-enabled 16-ampere monitoring plug-cum-security device, which, when connected to any appliance, helps control it remotely through Be-Connected mobile application or the web application (supporting Android as well as iOS) developed by the company. The solution also provides customers with major consumption data and insights that help them reduce energy wastage, slashing their utility bills and giving them full device control. Betty connects to an input plug-point like any normal plug. The appliance to be used is connected thereafter.

When the user logs into Be-Connected mobile application and sets a schedule, the application connects to the cloud server; the company uses Amazon Web Services. The server triggers a command to Betty, which acts accordingly.

The Betty circuit primarily consists of an SMPS, a GSM-PCB (comprising majorly a GSM modem, current sensors, motion sensor and a microcontroller) and, finally, relay sections. When a device is plugged into Betty, the SMPS scales the current in accordance with the device capacity and forwards it to the GSM-PCB. Current sensors in the PCB detect the current consumed and the information is relayed to the microcontroller, where calculations take place. The data is calculated in the form of power consumption and currency, and displayed on the mobile application. As wireless connection is established through GSM, the user needs to have a network-enabled SIM card inserted into Betty.

The device runs smoothly on 2G speed, so slow network barely affects its functioning. Sharma shares the reason behind the choice of GSM support over Wi-Fi: “India is improving in its Wi-Fi connectivity, but it is still not in the best condition. Even 3G or 4G is not 100 per cent reliable. In comparison, 2G is ever-pervasive. It is available even outdoors.”

Once an on/off schedule is set, the information is stored in the server. Even if the mobile application is not working during the schedule, it will not impact the functioning of Betty. The device also has manual control buttons. Even 6-ampere appliances can be handled using a 6A-16A converter. Monitoring data from Betty is consistently stored on the server. In case mobile Internet is not available on Betty’s SIM, the device can locally hold consumption data for up to eight hours, which is displayed to the customer when the network returns.

If security mode is selected in the mobile application, the plug’s motion sensors will detect any kind of movement within a 9-metre (30-feet) radius and instantly trigger an alarm on the user’s mobile application.

The application allows user management, i.e., multiple users can have permission to handle the application and functions of Betty. All authorised users will receive notifications at the same time and get access to the data and controls.

Betty, the helper

Electricity is used everywhere, so essentially anyone can use and benefit from Betty. The company eyes small and large business offices, commercial buildings, SMEs as well as home-owners as the target consumers of Betty. The main benefit of Betty and Be-Connected application is lowered electricity bills and secured premises.

Scheduling helps users to ensure no appliances are running when not in use, saving a lot of energy wastage. Moreover, monitoring helps users understand where they can cut their electricity consumption and also see how much they are saving using Betty. The information through the application enables regular monitoring, planning and better scheduling of electricity consumption. Beyond Evolution claims an average of 12 to 15 per cent electricity cost reduction using Betty.

In the market

Betty is already available in the market. It can be purchased from any major online retail site like Amazon, Flipkart, Paytm and Ebay, or from the company’s website for ` 2499. The plug-n-play device has no installation hassles, the mobile application is user-friendly and self-explanatory, and there is no additional operational cost other than the connection expenses for the SIM inserted in Betty.

Betty is getting positive customer feedbacks—some even reporting up to ` 1000 savings on their household electricity bills. The company now plans Wi-Fi inclusion and other upgradations for the device, which will be rolled out soon.
