Sample of Australian energy company price comparison matrix

Are you so annoying of the Australian energy service company? The price sheet is always so hard to read, and the discount they offer is so unclear as well

I agree there are few websites that can help you compare the price of those energy company based on your usage, but those websites are usually sponsored by the energy company as well, so it’s hard to trust them sometimes.

I did some homework by myself, by comparing on those most popular energy plans from majority of the service providers, so I think it will be useful to share it out.

Let’s started with the basic concept of the energy service in Australia:

Distributor and Service Provider

  • Distributor: the energy infrastructure owner, not selling the energy directly to the user, only to the service provider

If you are in Melbourne, you can find your distributor from below map, or visit here


  • Service Provider: like a reseller, package the energy with plans and sell it to the users

Service Fee/Daily Charge and Usage Fee

Now it is more make sense that you can see there’s two types of fees included in the bill, "service fee/daily charge" and the "usage fee"

  • Service /Daily Charge Fee: This fee charged daily based as you can see from the name, you can image this is a kind of management fee, service fee or labour fee
  • Usage Fee: This is the fee you actually consumed the energy


You should be very carefully on the discount rate. Some company only discount on "Usage Fee" and some others discount on both

And when energy company advertising their product, they always only promote their discount rate rather than the actual after discount fee

Email Notification and Online Management

I was using Red Energy before switch to Dodo, one of the annoying thing was they only post your bill, which means when your bill lost for some reason (like posted to the wrong mailbox), there’s no way to track your bill.

So that is way email notification and online management portal is another my consideration.

Note: each area may have different price since under different distributor, and energy company may change their price anytime

If you are with my distributor, you can use my data to estimate your best plan

If you are not with my distributor, you can refer to my data, but may need to do your own homework

Price Date: Jan 2015

Data Source: Energy service company website

My Sub: Heathmont, VIC

My distributor: SP AusNet

My Choice: Dodo

My Reason: I’m not a strong energy user, so daily charge is more important to me

Dodo Promotion: Dodo has a referral promotion which give both of us 25 credits, comment me if you need my ref no.

AirWatch across datacenter MDM architecture design

I’ve been in enterprise mobility (formerly MDM) industry since very earlier when customers still hasn’t start thinking about high availability (HA) and disaster recovery (DR).

However, just because of MDM devices increasingly so fast, more and more enterprise start to look into HA and DR design for MDM platform these 2-3 years.

No matter which MDM product you are using, they all have very similar architecture designs, this is because of it’s still a standard web service which usually include some frontend (DMZ), engine(Internal) and backend(database).

Although you can always find some diagram from any of the MDM vendor, but most of the diagram you can get doesn’t include the HA and DR across data centers.

If you have ever implemented Office 365 with ADFS, you should be really easy to pick up the MDM architecture.

If you never played with any cloud infrastructure, you can have a look on my architecture diagram below which I designed earlier for AirWatch


AirWatch Architecture HA&DR Diagram with DNS failover


AirWatch Architecture HA&DR Diagram with F5 Global Traffic Manager


AirWatch Architecture HA&DR Diagram with Per App VPN


All the above diagrams are only for AirWatch cloud service architecture, the on-premise architecture will not be that hard if you can understand the cloud

How disks redundancy works in Synology NAS

Last time, we’ve configured the alert system in Synology DSM (DiskStation Manager)

This time, let’s test it out

I had a chance to replace one of the disk in my Synology 2 disks NAS DS-215j

So I’ve removed one of the disks from the NAS, and power it on again.

Just right after the NAS powered on, all the alerts are coming in the first minute:

a. The status on the NAS shows Yellow


b. The beep is keep beeping

c. I’ve got an email from Synology’s email server


d. My Synology “DS finder” app on my phone and iPad are both pop up

When I logged into DSM, I’ve got below information





What a great alert system, I love it.

Next, let’s fix the disk issue by replacing the old problematic disk with a new one

1. Power it off

2. Replace the old problematic disk with a new one

3. Power it on

4. Login into DSM

5. Navigate to Control Pannel->Storage Manager->Volume->Manage

6. Select Repair


7. Select the new disk


8. Confirm data lost on new disk


9. Confirm all information


10. Repairing


11. Adding new disk


Please note my disk space will automatically expanded by using the Synology Hybrid RAID after replaced by a different size disk


This is why I’m using Synology Hybrid RAID rather than RAID 1
