@irongarment There are many people here who have use ESP8266's (including myself) but the problem with doing this is the fact the remote commands are commonly encoded packet bursts so you lose a whole lot of control going this method. I ended up going with the Sensibo (https://sensibo.com/) which is far cheaper than the integrated option for my aircon unit and actually does far more too. They also have a full API so have this integrated with Home Assistant and Google Home.

I could have messed around with the ESP for a bit more to get the same functionality but it wasn't worth my time - an off the shelf solution looks far tidier and just works for me.

What control do you lose? The software I tried sends data packets identical to the remote control, i.e. there is nothing that the remote control does that can't be done.

I've been reading these Daikin heatpump threads with some interest. I've just bought a house with a Daikin ducted heatpump installed (FDYQ71 with 3 outlets) .

It has a BRC1E62 Standard Controller. Does anyone have one of these? I cant find any mention of it having IR input, so I assume I cant use any of the internet connected devices to control it (Sensibo, Black Bean etc). It seems like the only option is to get the SkyFi module added on, but that it probably isn't available, and even if it was, is not worth the cost or hassle.

Keen to hear if anyone has a Daikin ducted system and was able to get it controlled remotely.

Interesting to see this thread popping up again, given I’ve just had a component of my Daikin wifi controller replaced by Daikin. As with @Talkiet, ours uses the SkyZone unit, and is the (now discontinued) variant with the tablet interface (as discussed on an earlier thread on ducted systems). We’ve had huge issues with the WiFi on this system, with it constantly losing the connection to our own router (as opposed to the unit’s own AP, although that can also be ropey); earlier complaints to Daikin went ignored, but I tried again a month or so ago, and it wasn’t long until Daikin’s lower NI rep called by to check on the system, and was back within a week to replace the controller (ie, the tablet). Apparently the original tablet was an AliExpress-quality device that they later replaced with a better Lenovo one, which is what he has now installed for us. We haven’t really been able to determine whether the connection to the outside world is more stable as, since then, we’ve been having huge issues with our own WiFi (hope this isn’t part of the problem!).

In regards to the post immediately above this: this looks like the standard controller that we could have had fitted, and could still if we continue to have connection issues. My understanding is that, depdending on your model, you could have the WiFi unit connected to the in-ceiling unit, but that has its own issues. If it does play up, at least you wouldn’t risk losing the ability to even control the heatpump from the main controller like we have! (Your controller is wired back to the in-ceiling unit, whereas ours is wireless so if that goes down – as it often has – we have no heating.) But it’s a decent amount of money to add a function that may well not be terribly reliable.

On a more general note, I must say I was totally impressed with the support provided to me by Daikin this time around – I didn’t really want to involve the original installer, as they’d done a pretty p!ss-poor job and didn’t seem to fully understand the complexities of a ducted system, so to have the Daikin rep make two visits to sort this was a real surprise (including making a trip from Wgtn to sort out mine and another person’s problems). He said Daikin’s operations in NZ have been separated from the Aus business.

Very interesting. Are you able to PM me with a contact for Daikin NZ please? I am still keen to sort this out if possible. Unfortunately I suspect the wifi unit I have is intrinsically dodgy :-(

I never got the tablet installed as Daikin withdrew it from Market between me accepting the quote and them coming to install.

I found a PDF brochure here:
https://www.lawsonair.com.au/daikin-fdyq71-7.1kw-premium-inverter-1-phase-ducted-system-air-conditioner

In the brochure on page 9 it mentions the BRC1E62 Standard Controller, and claims that a SkyFi wifi interface is an optional extra.

Below that it mentions a BRC4C62 Infra-red wireless remote control kit. Maybe that's what you want?

I have a Daikin ducted system (3 zone) with that controller. I also have the skyfi interface. It is wired in as if it was a second controller. I have it controlled through homeassistant and Amazon Echo (Alexa, turn on the aircon) but the control is unreliable. I think it would probably be better to get the IR kit and then get one of the many wifi-IR control systems... Although it's more steps, it sounds like it will be more reliable.

PM sent.

Well, you dodged a bullet there; the tablet proved itself to be just one more component to go wrong, and was a fundamentally flawed design in that it did not provide for a backup in the situation the wireless connection went down. As the Daikin rep said himself, it would have been quite feasible to still use a tablet but connect to the ceiling unit via a wired link. Apparently, the company that developed the tablet-based system went into receivership, which hasnt helped...

...and this is why an open source diy solution is preferable.

A little bit of digging finds this:
https://bitbucket.org/JonathanGiles/jdaikin

But it's Java.

Seems to work with OpenHAB (for appropriate values of 'work')
https://community.openhab.org/t/http-commands-for-daikin-brp072a42-wifi-control-working/10314

Keep looking.

My heat pump is Panasonic, so I just send IR commands to it.

I've been using the BRP072A42 unit recently and not had any issues yet.

@irongarment I am a fan of ESP devices in general but disagree, as do others, around your assertions that it does exactly the same as a wifi module, because it doesn't. Its great that the IR solution works for you, but it isn't perfect for everyone.

I've had the BRP072A42 installed in my Cora unit for ~7 months now. No connection or reliability issues and I quite like the look/layout and usability of the D Mobile app.

Happy customer here.

I have the BRP072A42 module and I can say it is awesome. It uses http to communicate so is super simple to write your own code control it.

Each command has a response so you get feedback that the command you sent was received and that it was correct.

I have had no issues with connectivity what so ever.

One of the main reasons I went with a Daikin heat pump was because of this wifi module. It beats those simple third party devices that just mimic a remote.

My reasons are:

1) It is not yet another device I need to find a power point for and have in line of sight with the heat pump.

2) I can get information back from the heat pump. It has commands to get the current status, so I can display if it is on/off, settings etc. This means that I can have the correct information displayed regardless of if someone changes a setting via the standard remote, their mobile app or with my custom code.

3) Super simple to write my own code against as it is just http commands and the API can be found here https://github.com/ael-code/daikin-control

The main thing they can't do is get information from the heat pump. That is the reason the IR solutions are a no go for me.

Ok, but a lot of heat pumps just don't have network connectivity, and for many people the cost of adding a BRP072A42 at about $150 to their Daikin is too expensive. And no-one is going to replace their heat pump with a Daikin just because it has this feature.

It is true that the heat pump remote controls send data in only one direction, so a smart home automation system will cache the last setting and report that as the current setting when asked. The effect is the same, and that's what Pebble and other similar systems do. If you hide the remote then no-one can alter the settings without going through the home automation system, so that gets rid of that problem. Similarly if the reported (cached) settings don't match reality then (assuming you want those settings) just send the previous command again.

I still think that $10 spent on an IR emitter and a cheap micro is the best solution, especially for heat pumps that do not have a wifi interface. Obviously not for you, because you have a wifi interface. And obviously not for non-geeks, but they wouldn't be hanging out in the geekzone, would they?
