Sorry if this is a dumb question but what's the difference between the two brands?
Not dumb at all. Heavy Industries is the quality brand that wins awards, gets great reviews etc.
Electric, not so much.
I believe they are made by different divisions of the company.
Go with Heavy Industries. They do this cash back twice per year.
Read the T&C's though. They are sticklers for the rules, so make sure you have all the info they need or you won't get the cash back.
Where did you get this info from? It seems that Choice favours MHI, but when you look into it more, it's not so clear which is better. They're both great though, and the after-sale support and install on the product will make much more of difference than the brand you pick out of these two. Check which brand your preferred fridgies likes to deal with.
Also note that MHI has minimum heat of 18 degrees compared to 16 degrees with the ME which could be important if in a bedroom and you plan to run it overnight.
@Never pay retail: @Never pay retail
MHI has an Eco mode that cuts the minimum temp by 2.5 degrees and reduces the fan speed to a quiet setting (only one speed) so it's effectively the same for sleeping
It was originally one company that divided and split into two. Same name but two entirely different operational models and products. MHI is the one to go with, ME is the cheaper/inferior product. Brother in law is a sparky and he won't bother supplying and installing ME products anymore.
Got this cash back few years ago, had to chase them constantly to get the cash back. Essentially got paid after waiting months and took many emails and phone calls.
Had the exact same experience, many many many emails, their supposed troubleshooting seemed to be designed (or through complete and utter incompetence) to deter me from availing the cashback. Codes didn't work, had to log in to this or that, then try a different model code or this or that.
Tossing up between this and ME I decided to go with ME as it appears to have excellent HA integration (getting it installed next week so fingers crossed).
Do you plan on using the official wifi module to integrate with HA?
Supposedly that's the best way of integrating it - uses 'echonet' and can talk to HA locally. Here's the results of my findings with perplexity:
Based on your requirements for Home Assistant integration with Daikin, Mitsubishi Electric, and Mitsubishi Heavy Industries air conditioning systems, here's a detailed comparison focusing on compatibility, methods, known issues, and potential solutions:
Daikin Systems
Integration Status:
Supported via official integration for specific models:
Local API models: BRP069A/B series (EU), BRP072A (US/AU), BRP15B61 (AirBase)
Newer models (Onecta cloud API) require cloud connectivity
Z2M compatibility: Not natively supported; local IP or cloud integration required
Method:
Local control via UDP (ports 30000/30050) for supported hardware
Cloud control for newer units without local API
Manual IP configuration in Home Assistant
Known Issues:
Intermittent "Failed to set up" errors due to network payload issues (#133376)
Firmware updates (e.g., BRP084Cxx v2.8.0) may break local API
Authentication failures with newer models (Forum report)
Potential Fixes:
Restart Home Assistant to resolve temporary setup failures
Firewall adjustments for UDP traffic (ports 30000/30050)
Community-developed alternatives like FAIKIN for cloud models
Mitsubishi Electric
Integration Status:
Fully supported via multiple methods:
Local ECHONET protocol (requires MAC-568IF-E WiFi adapter)
MELCloud cloud integration
DIY ESP-based solutions via CN105 port
Methods:
Local: Enable ECHONET in official app → Use custom component
Cloud: Official MELCloud integration
DIY: mitsubishi2MQTT firmware for ESP chips (MQTT/Z2M compatible)
Known Issues:
No major issues reported in sources
ECHONET requires specific adapter (MAC-568IF-E)
Potential Fixes:
ESP-based solution provides local control without cloud dependency
Multi-language and Matter/HomeKit support in active development
Mitsubishi Heavy Industries
Integration Status:
Limited official support
No native Home Assistant integration
Community projects in early stages
Methods:
ESP-based solutions (experimental, requires collaboration)
IR blaster (fallback option)
Cloud APIs via third-party hubs
Known Issues:
No direct local API documentation
Hardware differences from Mitsubishi Electric complicate reverse-engineering
Potential Fixes:
Community efforts to extend mitsubishi2MQTT support
IR blaster with broad compatibility (e.g., Broadlink RM4 Pro)
Got a couple of ME splits installed recently, and they're almost too powerful. We put a 2kw unit in a small bedroom and on 24 cool mode it turns it into the Arctic. The 9kw unit in the main living area comfortably warms our entire upstairs on 23 heat mode at lowest fan speed.
That's awesome to hear. There's so much shit-talk about ME around here (mostly from ppl who haven't had ME units haha), so happy to hear a positive experience. Excited to get it installed.
I got the Avanti PLUS Multi Split DXK12ZSA-WF1 3.5 kW and Avanti PLUS Multi Split DXK18ZSA-WF1 5 kW.
Using them with the built-in wifi module and https://github.com/jeatheak/Mitsubishi-WF-RAC-Integration. Works well so far. I also tried their official app, and it works, but it also feels very scrappy. The HA integration is actually neater
Also reminder that there's an NSW incentive available if your installer is signed up for the scheme.

Damn, I wish I knew about this two weeks ago…
Make sure to get Mitsubishi Heavy Industries not Mitsubishi Electric, completely different arms and manufacturing.
Personally ive own/used Kelvinator, Panasonic, LG, Samsung, Fujitsu and MHI. MHI by far was the best performer. DYOR but yeah good luck! :)
Yes regret not going MHI after going Hisense to save some cash on the extension/reno $16k vs under $12k.
the Hisense are a bit noisier than I would like,noisier than our previous 24yo Daikan.
Where the hell do I find prices for these units? Do I need to get a quote first?
They're not sold in as many places as other brands including Mitsubishi Electric.
Bunnings in Armadale, WA used to sell them. Some electrical stores sell them. Some sparkies & air con installation co's sell them.
Shop around installers.
I think all bunnings sell them, or can order them in.
Anyone got recommendations for installers in Melbourne (Eastern suburbs)
I have used Chris (0411 621 182) to install 5 x Mitsubishi Heavy Industries units over the past 20 years at different properties in Melbourne (SE suburbs). I originally got the contact from The Good Guys as a local installer. I always just bought the unit myself and he installed it. There were no issues with any of those units during this time.
Great value with the cashback. These are amazing for heating too, not just for cooling. Split System reverse cycle used as heating will be far cheaper to run than gas heating, even without solar. With solar even cheaper again.
In an old house ran a couple of splits for the last 10 years and cut off the gas (stove was electric and changed hot water to heat pump). New house have got rid of gas ducted which was costing $300+ per month in gas bills and installed a Panasonic ducted unit - it is nothing short of amazing. So quiet and a much nicer heat. Used Air Touch 5 and temperature sensors in each zone and now get even temps in each room compared to before. Electricity consumption is quite reasonable given the size of it, and we have it on 21 degrees now in winter. Solar helps make it cheaper again. Before with the gas heater, didn't put it higher than 18 as already getting $300 gas bills per month, so ended up with expensive bills and still a bit cold. Now warmer and much lower bills.
The reason air conditioning/reverse cycle is cheaper to run than other forms of heating (ie fan heater) is that it is a heat pump, not generating heat (ie fan heater). To this end, for one unit of electricity consumed, you can get 4-5 units of heat. For a fan heater it is 1 unit of electricity to get 1 unit of heat. Therefore split systems can be 70-80% cheaper to run than a fan/oil heater.
Any recommendations for installers in Perth?
Fuuuuuu, I bought two indoor and one outdoor unit just a few weeks ago.
Ah, never mind. This deal only counts when you buy a single indoor-, and a fitting outdoor unit. Not for multi-head installations.
Awsome, getting one installed in a week, perfect timing :)
