ESPHome-gea — GE Appliances on the local bus (dishwasher, washer, dryer, oven)

Connect your GE appliances to Home Assistant — no cloud, fully local

Hi everyone! I’ve been working on an ESPHome external component that lets you
monitor and control GE appliances (dishwasher, washer, dryer, oven) via the
GEA3 serial bus — the built-in service port found on most modern GE/GE Profile
appliances. No SmartHQ account, no cloud dependency, 100% local.

How it works

Wire a cheap ESP32 into your appliance’s service port. The component reads and
writes every data point on the bus — door state, cycle name, water temperature,
time remaining, error codes, and more — and exposes them to Home Assistant as
standard entities.

Each piece of data is identified by a 16-bit ERD (Entity Reference
Designator). The component automatically logs every ERD it sees on boot, so
reverse-engineering a new appliance is straightforward.

Features

Read & write — sensors, switches, selects, numbers, buttons, text sensors, binary sensors
Auto-discovery — every ERD on the bus is logged on boot
Resilient — periodic re-subscription recovers state after appliance power cycles
Flexible decoding — 13 numeric types, raw hex, ASCII, enum option maps
Edge-triggered automations — on_erd_change fires on rising/falling/any transitions
Bus health diagnostics — CRC errors, TX retries, dropped requests, connection status

Hardware

You need an ESP32 and an adapter to tap into the appliance’s GEA3 jack:

mulcmu/esphome-ge-laundry-uart — open hardware (KiCad + gerbers), big thanks to @mulcmu whose reverse-engineering work made this possible
FirstBuild GEA adapter — commercial option, no soldering required

Tested on the Seeed XIAO ESP32-C3 (compact, 3.3 V, native USB).

Nice work!

I’ve got a FirstBuild GEA adapter on my dishwasher, and using their HACS integration, but will definitely check out your component. Could help me avoid getting buried with ALL the entities – there are a BUNCH showing up in HA on dishwasher.

I will certainly consider plugging your ESP into one or more of my three GE appliances that are already factory-built “smart” --but cloud-based. Will be interesting to see what info they’re putting on the GEA3 bus but not surfacing in the mobile app, and/or what appears in current HACS “SmartHQ” integration. Certainly would be nice to keep all local.

One question: any chance you can do something similar for GEA2 ? My fridge is the only GE appliance I’ve got for which I can’t get data. I’d certainly be willing to test.

CaptTom · April 27, 2026, 11:23am

Nice work! I don’t have any GE appliances, but knowing there’s something like this available would seriously tip the scales when I do go to buy.

mulcmu · April 27, 2026, 12:00pm

My PCB has the hardware needed to support GEA2. I’ve been using it for a GEA2 dryer with esphome (external component for GEA2 in same repo as the PCB).

mguaylam · April 27, 2026, 2:11pm

I’ve implemented GEA2, let me know if it work or not. I can’t test this.

mekaneck · April 27, 2026, 4:47pm

I’ve procured 5 of the mulcmu adapters and I also have 1 of the firstbuild adapters. I have 5 appliances that are all GEA2. The 1 firstbuild adapter I have working, but haven’t yet been successful getting any of the mulcmu adapters to work. So far I have only tried the geappliances fork that works for GEA2, and haven’t tried your ESPHome code. Hopefully will get a chance to mess with it more next weekend.

mguaylam · April 27, 2026, 5:06pm

Im curious what are those GEA2 devices and how old they are?

mekaneck · April 28, 2026, 12:29am

Washer & dryer which are about 8 years old, and then fridge, dishwasher, and oven which were left by the previous homeowner but looked relatively new at the time so probably 10 years old. There is a GE microwave too which I haven’t checked to see if it can be connected, but I don’t really have much interest in any data from it either.

mguaylam · April 28, 2026, 1:09am

Nice. Can’t wait to see if my stuff works.
I wanted a microwave from GE so bad since I’m annoyed to set the time when the power cut off. Lucky you.

mekaneck · April 28, 2026, 2:17am

Just looking through your docs, noticed that you don’t specify the pins for GEA2. Under wiring and also in the hub doc, the GEA2 wiring should be 10 & 9 (Rx&Tx) for the firstbuild adapter.

uart:
  id: uart_gea
  tx_pin: GPIO9
  rx_pin: GPIO10
  baud_rate: 19200

Since I haven’t got the mulcmu adapter working yet I can’t confirm but per the schematic it is set up for 10 & 5 (Rx&Tx) with a solder bridge jumper that can connect 9 to the Tx.

Another suggestion is for GEA2 you could do what the GEA2 fork of the home assistant adapter software will do on first connect: It will find out what appliance type it is connected to, and then poll every ERD that appliance could potentially use. After about 30-45 minutes, it will have run through every potential ERD and it stores the the ones that responded in flash memory. From that point forward, it just continually polls the ones in memory.

mguaylam · April 28, 2026, 5:21pm

I agree with the proposed enhancements.

I’ll add pin documentation.

I’m also adding scanning of the legacy ERDs, Should be around 2000 of them.

Hello, I got a firstbuild adapter last week and I am trying to integrate with a US-specific GE 50 gallon water heater. My model is PF50S10FPY but from my understanding, all the latest generation models are identical and speak GEA3 natively. This model is listed as compatible

I wanted to try the esphome method first since the official integration looks very heavy. I uploaded this config to try out:

I am unable to read the model number which I think should have been populated, and almost none of the ERDs from the official firmware's yaml

I am probably doing something wrong here. Is there anything in my setup that looks odd?

I also see this in the messages now, so I think perhaps the previous src address was right?

Looks like both 6F and C0 are sending status updates to two addresses you tried for the adapter E4 and BE. The E4 address was used in the example docs but it is close to the E0 to E3 control bytes used for the protocol. The wifi adapters seem to use addresses that start with 0xB_

Did you get anything in the logs for ERDS from 0xC0? Did the 0x6F get auto identified by the esphome code, I didn't see it in the yaml. Try adding dest_address: 0xC0 to the GEA hub.

has_hass · May 8, 2026, 8:08pm

Thank you. This was the missing link.
I am getting back ERDs that definitely belong to a water heater. The model and serial are blank, but I see several non-empty values that I can play with. Thanks! Let me see if I can get a good enough template and I'll submit the changes back to the repo.

0x6F might be the Wi-Fi module or another module and replied first so the code took that when it auto-detected.
