Firmware Update For Your BroadLink RM Pro

I was alerted by one of the visitors on my page that there’s an update for the RM Pro. The most important feature for this update, is enabling remote access for your RM Pro. Before this update, the RM Pro can only be accessed from your LAN. Now you can control your devices at home via the internet.

Finding the option to upgrade the firmware was a bit tricky. The BroadLink documentation is not that fantastic. I ended up figuring out the upgrade on my own.

First, you have to get to the list of RM Pro you have. In my case, I have 1.

Go into the device details and you see the firmware update option.

On this screen, you should expect to see the new firmware and an option to upgrade. I didn’t get a screenshot before I upgraded, so this is the result.

After the upgrade I had problem connecting to the RM Pro. I ended up reconfiguring the RM Pro again. The cause of the problem was not clear.

So after the upgrade, the remote access now works. I’m caught up with research on geospatial topic these couple days. Shall come back to the RM Pro when I’m done.

Spanking Clean Air-Con

I always did simple maintenance of my air-conditioner at home. There was no temperature and cooling problem, so I just washed the filters and vacuum the fan unit insider. That was good enough to restore the air flow etc.

Just before Chinese New Year, we discovered something. Water was dripping in large amounts from the compressor unit outside. It is normal for light dripping because of condensation, but at the amount, I’m really not too sure.

After doing some research. I suspect it’s the bad air flow going through the fins of the fan units, resulting in either a back draft or accumulation of the cold gas at the compressor. The cold temperature on the compressor in turn caused excessive condensation. I decided that I want to do a complete chemical wash for the fan units. In any case, I haven’t done one since I installed the air-conditioner 7 years back. It’s actually about time for a good cleanup.

Yesterday, my air-con technician came for the wash. This was how the fins looked like before the cleaning started.

The fins on the fan unit were all dark. I can’t actually remember how it looked like when it was first installed.

The chemical wash involved spraying a combination of acid, detergent and stuff. There’s actually fumes produced during the process. The chemical is left to soak through for a while before flushing it off with water.

The smell wasn’t so pleasant, so keep the kids away when the job is being done. If you noticed, the colour of the fins is now different. Besides getting rid of the oxidation, the trapped dirt between the fins are always being flushed out. Imagine the amount of dust we are breathing in all these time.

And this was the outcome.  Clean. From dark colour back to aluminium colour.

The whole process to clean one set took about 30 – 40 mins. The whole fan unit has to be dismantled from the wall. Note that the air-con trunking has to be opened up to disconnect the pipes from the fan unit. There’s a little mess from this.

After the cleaning, the air-conditioner is left to run for a while. For 1, we need to get rid of the chemical smell and 2, the air-con technician has to ensure that all the fan units are cold. Otherwise it could mean a leakage somewhere.

So after going through this effort, did it fix the problem I was trying to solve? i.e. the dripping compressor. It definitely did. I checked twice, once in the afternoon after servicing and this morning. The compressor ledge was dry. The dripping from the compressor has stopped. This is a big difference from 2 weeks ago when it was dripping furiously.

Hope this helps for people with same issues. Try this first before you start to install air-con trays or some kinds of repairs that might not solve the issue completely.

Mini Cake Maker

Yes, mini cake maker. :) I’m not only about geek and stuff. I do the family things too. :p

This has been on my daughter’s wish list for a while. So I ordered one of these when I came across it on Taobao. The cost of this is about SGD $20. On hindsight, I think I could have gotten one for about the same price locally. :)

The device is simple. No timer, no knobs to adjust etc. 2 LEDS to show that it’s powered on and whether it’s heating. Instructions say that you pre-heat it and when the heating light is on, you start putting in the dough or cake mix to start ‘baking’.

We have no experience with this, so we tested with 1 cake.

After 4 mins, we got this beautiful cake. I tasted it and I must say it’s really not bad. Look wise, we thought it was a bit raw, so we tried 5 mins on the next round.

Round 2 turned out slightly charred. So the magic number is actually 4 mins, or around 4 and a half mins.

This is a pretty interesting machine. Along the way, we had other ideas. Make we could make tako-yaki with this, or we could fry eggs? I think this could a good companion during BBQ and parties for make simple finger food without activating your whole oven. For 20 bucks, it’s a steal. :)

This is the link on Taobao.
