Fujitsu AC (heat pump) integration via ESPHome [ESP32]

Grant, we have some people excited about this! Are you up for this?

For the rest of us: We would need to guarantee to Grant that there are no warranties or guarantees.

I’d also love to purchase one if you do end up making some

First off, big thanks to @FOSV for thePCB designs and @rabbit-aaron for the esphome port.

After a second attempt, I believe I have a working PCB! The LED lights up and the Atom turns on while connected to the indoor unit’s connector labeled remote. However, I am struggling to get the software working. I used the Old serializer new driver branch and was able to get the web server to load and integrate with home assistant but it does not seem to communicate with the indoor unit.

It says it set the temp but nothing actually changes and the settings are wrong. I have pin 22 set as tx and 19 as rx and master set to true. I’m thinking it is software related but it could totally be a bad solder joint. Any help would be appreciated.

I would be happy to make a batch of these and ship them to whoever wants one once I can get mine working to confirm they work.

Has anyone had luck with zone control? :eyes:

The software is not working perfectly. Sometimes it sets the temperature immediately, other times it doesn’t respond and I have to set it several times. Usually I can set 1 degree plus or minus per second.

I think a synchronization with the Fujitsu communication protocol is missing.

But usually it’s working… :slightly_smiling_face:

I use this integration with homeassistant and multiple Sonoff NS Panels

I described it little in this post: here

Any more luck getting the issues resolved?

I presume GitHub - dgrnbrg/fuji-debug-protocol is your code? How has it been working for you?

Unfortunately, I have not. I also haven’t really had much time to work on it either, hopefully will have some time next week.

Yes it does.

Thanks. I am trying to keep 100% local.

Finally my integration works. In my case it was necessary to switch off the switch number 1 at the master wall unit.

I’m using the MCP2025-330E/P chip and the
AZDelivery ESP32 ESP-WROOM-32 NodeMCU.

The code I’ve uploaded into the ESP32 is the normal one, not the single core version.

Hello. My air conditioner is ARXG24KMLA. I have a UTY-RLRY wall remote. This remote has only 2 wires. Has anyone managed to connect it to HA using ESP32 and MCP2025? I found a diagram of the main board of the unit where you can see that the remote is connected to connector Y1 and Y2. It seems to me that the missing third wire, i.e. GND, can be connected to connector Y3 on the board. Do you think this could work?

Hiya. I have one of the Fujitsu mini splits ASTG09KUCA which does not have a wired controller but an IR remote and no wifi capability. I would like to get control of it in home assistant via ESPhome. Will the above work for me too?

I thought about doing what I did with my Daikin air con where I soldered the 5v, gnd, Rx and Tx to the appropriate pins with an ESP-01M allowing me to control it fully using Climate IR supported for Daikin(hail mary attempt which worked). The ESP-01M essentially replaced/works with the built in IR receiver.

ESPhome Climate IR also seems to support Fujitsu but I don’t have a video to follow like I did for Daikin. I do have a ESP-01M prepped for the ASTG09KUCA but wasn’t game to go ahead unless I know it would work etc.

Trying to work out my options really. Any help would be much appreciated. I have very little, next to none coding skills.

It is difference protocol it is Homebus, you can check this project GitHub - Arnold-n/P1P2MQTT: Monitor and control Daikin/Rotex (hybrid/Altherma) heat pumps via the 2-wire P1/P2 thermostat interface with an ATmega328P, ESP8266, and electronics. The P1P2Serial library and P1P2Monitor program perform low-level bus operation, the P1P2-bridge-esp8266 program interprets data from/to MQTT supporting Home Assistant MQTT discovery. P1P2Serial may also be used for other Japanese Home Bus System based standards: DIII-NET (F1/F2) bus, Mitsubishi M-Net bus, Toshiba TCC-Link, Hitachi H-link, Panasonic/Sanyo SIII-Net, Haier, York, and others.

Hi guys, I’m going crazy. I’m trying to make the circuit but I’ve already burned 2 esp32… I really don’t have much knowledge of electronics but I think I’m doing everything as in the diagram that some of you have shared. It could be a rookie mistake for sure. Does the MCP2025-330E/P chip connect directly to 12v? I think I’m burning the boards due to the voltage that comes from the Rx and Tx of the chip to the esp. Please someone who can help me. Thank you.

Everything is already working. It was a rookie mistake as I assumed… I thought that with the reducer it was only enough to configure the output voltage with the buttons and not turn the screw…XD. Luckily I measured the output and I already realized. Since so many things could go wrong, I didn’t pay attention to the most basic things. Thank you very much to everyone who has contributed to this thread, having done it the first time but that is what happens the first time. I repeat, thank you all very much, it works great.

Hello.
I need your help. My board is ESP32-WROOM 32 ESP32-WROOM_32 (CH340C). After uploading the code to my ESP32, the new device does not appear in HA. When I want to add the device manually, I get the message :
"Can't connect to ESP. Please make sure your YAML file contains an 'api:' line.".

Additionally, I cannot download the log via WiFi. I get the error

INFO ESPHome 2024.10.2 INFO Reading configuration /config/esphome/f.yaml... INFO Starting log output from fujitsu.local using esphome API WARNING Can't connect to ESPHome API for fujitsu.local: Error resolving IP address: [Errno -5] No address associated with hostname (AP IConnectionError) INFO Trying to connect to fujitsu.local in the background.
