Press [WEEK" button to set weekday for timer. Multiple weekdays can be selected. ex: if selected [MO", the timer will only apply on every Monday; if selected [ MO, WE, FR", the timer will apply on every Monday, Wednesday and Friday.
Press [RES/RCL" button to cancel the selected on or off timer. The screen will show "-- -- : -- --" , the timer is canceled.
Press [RES/RCL" button again to reactivate the timer.
When timers are set, press [CLOCK" to quit timer setting and return to clock.
5. Random function
Press [RANDOM" button to activate random function, press again to cancel function.
System only runs random function when [AUTO" is on.
Random function will automatically start the timer from 2 to 32 minutes after the setting.
ex : if timer 1on was set to 19:30 with the random function on, the timer will activate randomly between 19:33 to 20:03.
if timer 1off was set to 23:00 with the random function on, the timer will activate randomly between 23:02 to 23:32.
To avoid overlapping, make sure to leave a minimum of 31 minutes gap between different sets of timer.
6. Manual control
Displayed features:
ON : socket turns on.
OFF : socket turns off.
AUTO : socket turns on/off automatically via timer.
Manual ON setting
Press [ON/AUTO/OFF" button to switch from [AUTO" to [ON".
This mode allows socket of the device to power up. Power indicator will light up.
Manual OFF setting
Press [ON/AUTO/OFF" button to switch from [AUTO" to [OFF".
This mode turns socket of the device off. Power indicators will turn off.

Q&A
Q: Why won`t my timer turn on?
A: It`s out of battery, you can charge the timer by plugging onto any power outlet. Charge the device for at least 15 minutes. Then press [RESET " button to reset the device.
Q: Can I set seconds of the timer?
A: No, the smallest time unit is minute.
Q: Does my timer keeps old settings without being plugged onto a power outlet?
A: Yes, the timer has an internal battery, it allows the timer to save settings without a power outlet.
Q: Is the battery rechargeable?
A: Yes, the battery is rechargeable. We recommend to charge it for 4 hours so the battery is fully charged.
Q: Does the timer needs internet connection?
A: The timer does not need internet.
Q: Does the screen have back light function?
A: It doesn`t support back light.

Analyze the opportunities, developments and challenges of blockchains in the IoT space
Blockchain, a form of distributed ledger technology, has captured significant attention beyond the realm of cryptocurrency since 2014. From blockchain + IoT to blockchain + security, and blockchain + finance, the integration of this technology with various industries is rapidly expanding. In this article, we explore the opportunities, developments, and challenges that blockchain presents in the Internet of Things (IoT) space.
Blockchain technology, often associated with Bitcoin, is actually a broader concept encompassing many different platforms. It is reshaping digital services across multiple sectors. According to Don Tapscott, a pioneer in the digital economy, blockchain may be even more transformative than the internet itself. When combined with IoT, it offers immense potential, which we will delve into later.
By 2019, IDC predicted that 20% of IoT deployments would incorporate basic blockchain services. This highlights the growing recognition of blockchain’s role in enhancing IoT systems. The field is evolving quickly, not just within financial institutions but across various industries. Financial technology was one of the first applications of blockchain beyond digital currencies, but now, the convergence of blockchain and IoT is becoming a strategic focus for many companies.
The combination of distributed IoT systems and distributed ledger technology is particularly powerful. As IDC analyst Frank Gens noted, blockchain is increasingly vital in next-generation security solutions. While it may not solve all challenges of the digital economy, it plays a crucial role in securing and managing IoT ecosystems.
Forrester has also recognized the potential of blockchain in IoT solutions, emphasizing how it can enhance device communication, interaction, and decision-making. By enabling peer-to-peer transactions and smart contracts, blockchain supports more autonomous and secure IoT environments.
Smart contracts, a key feature of blockchain, automatically execute when specific conditions are met. This capability allows for efficient and transparent interactions between IoT devices, improving compliance, functionality, and cost-effectiveness. For example, IBM has integrated blockchain into its cognitive IoT systems, creating a synergy between AI, IoT, and blockchain technologies.
IBM's application of blockchain in logistics showcases its benefits. Through smart contracts, they track individual items and packages, offering improved audit trails, accountability, and transaction speed. According to IBM, the three main advantages of blockchain in IoT are building trust, reducing costs, and accelerating transactions.
Despite its promise, the integration of blockchain and IoT faces several challenges. Technological issues, such as security and scalability, must be addressed. The lack of mutual trust among IoT devices is a major concern, but blockchain's decentralized structure helps mitigate this by enabling consensus without a central authority.
Operational challenges include aligning business models and ensuring cooperation among stakeholders. For instance, in logistics, multiple parties must agree on processes and data sharing. Blockchain facilitates direct, secure data exchange between devices, reducing reliance on centralized systems and lowering computational costs.
Legal and compliance issues also arise, especially regarding responsibility when automated actions are taken based on smart contracts. These challenges require careful consideration and regulatory alignment.
In his book *Either Digital, or Dead*, the author highlights how blockchain addresses critical IoT issues such as scalability, single points of failure, and trust. By providing a secure, time-stamped infrastructure, blockchain enables direct asset transfers between devices, eliminating the need for intermediaries.
The insurance industry is one of the sectors exploring blockchain and IoT integration. Smart contracts and enhanced claims management are key use cases. As IoT data becomes more real-time, insurance policies can become more dynamic and personalized, shifting from traditional telematics models.
IDC predicts that the insurance industry will be one of the fastest-growing sectors in terms of IoT investment. With the rise of smart contracts and automated processes, blockchain is set to play a pivotal role in shaping the future of insurance and other industries.
Overall, the convergence of blockchain and IoT presents exciting opportunities, though it requires overcoming technical, operational, and legal hurdles. As more companies adopt this technology, we can expect to see a more secure, efficient, and decentralized digital landscape.
