Send and Receive Whatsapp Message on Node-RED

by

Whatsapp has recently become a very popular platform for messaging, with its versatile features and functionalities. Personally for me, I use whatsapp for communication on almost everything. We have all sorts of Whatsapp groups from families, in laws, siblings, cousins, works, management, departments, and etc.

One of the limitations on Whatsapp is the limited API access. You will need to be on Whatsapp Business or some other paid services to be able to use the API to send and received message on Whatsapp from an automated system or a custom bot.

In this article, I will share a method I found that allows you to send and Receive Whatsapp messages from Node-RED using the plugin node-red-contrib-whatsapp-link, for free.

Issue With Node-Red node-red-contrib-whatsapp-link

by

I’ve recently installed Node-Red on my home server, which is a good tool for simple automation. I’ve used it to configure some automation to send out Whatsapp messages in some Whatsapp groups as reminders for the members of the groups.

To enable Whatsapp in Node Red, I install this additional Node called node-red-contrib-whatsapp-link. One major reason for me to use it is because it does not require any third party APIs or any subscription to use it. It can simply link to your whatsapp account and you can use Node-Red to decide what to do with the message received, or to send out any message to a person or a Whatsapp group.

However, while using this Node, I face a few issue, and I will share on how I solve each of the issue in this article.

Sony NW-A105 Battery Mod

by

Sony NW-A105 is a very well-known Android DAP that was released around the end of 2019. As discussed in many forums (head-fi forum) and reviews, a significant downside of this Android DAP is the Battery life. Some members in the forum even shared steps to disable background services and run the DAP in airplane mode which helps improve the battery life, but it is still mediocre.

In this article, I will share on how I mod the battery on my A105 to increase the battery capacity.

Chord Mojo Bluetooth Receiver

by

I have recently purchased a 2nd hand Chord Mojo and for me, it sounded great and definitely an upgrade over my Galaxy Note 9 3.5mm jack.

Chord Mojo

However, there are 2 major complaints/issues that I have with Chord Mojo:

  • The lack of Bluetooth receiver function. It requires Chord Mojo to be always connected through wire to either my Android phone or my PC/Laptop.
  • The use of Micro USB port that is outdated for the DAC and charging. All my other device charge through USB C.

In this article, I will share how I upgraded my Chord Mojo to solve both my Bluetooth receiver and Micro USB port problem.

DIY Water Tank Handler

by

I recently purchase an instant hot water dispenser by Xiaomi Viomi, from Lazada (link). The dispenser works very well as advertised. It really instantly dispensed hot water, I guess near to boiling level (100 degrees). The only complaint from me is that it produces quite a loud pump and boiler sound when it dispenses water. I guess that is fair as the boiler is capable of heating the room temperature water to 100 degrees in a matter of a few seconds.

One very good advantage of this hot water dispenser is that the water is kept in the water tank at room temperature. It does not heat up the whole water in the tank like the conventional electric Thermo pot that actually wasted a lot of electricity in keeping the temperature at a desired level. The boiler in this machine only starts to boil the water when you press the dispense button. Another advantage of this type of hot water dispenser is that you don’t need to wait for the whole water tank to be boiled before you can enjoy a cup of coffee. After you’ve refilled the water tank, pressing the dispense button gives you instant hot water for your coffee.

Free Upgrade to Windows 10, Still

by

I recently purchased a second hand PC, that it came with Windows 7 preinstalled. I have already upgrade the OS in my laptop from Windows 8 to Windows 10 and I am quite used to Windows 10 features, especially the mouse scroll feature that doesn’t require the windows to be on focus. This feature is not available in Windows 7 which really bother me dealing with multi windows.

Microsoft did offer Windows 10 free upgrade for Windows 7 and Windows 8/8.1 user but I missed that window that ended on 29th July 2016. Searching for alternative way for Windows 10 free upgrade, it brought me to a few page saying that the free upgrade is still possible now (end Dec 2016) by accessing this page (link)
