Dometic Fridge Monitoring

Configuration
1

Hi, I have what I thought to be a hugely popular camping / RV etc fridge from Dometic, a CFX3. This fridge has both Bluetooth and WiFi monitoring from the CFX3 app.

I was surprised to find no information at all scanning through the integrations, HACS or just google. I was half expecting it to pop up in the discovered integrations when I brought in range of a Bluetooth proxy … but alas can’t find anything about this fridge in the home assistant world.

So, I guess my question is… am I doing it wrong? Have I overlooked something obvious? Or are people just not using these fridges?

I think this is not used in a home environment enought to include it in hass or create a custom integration for it.

I’ve looked into any partner companies, but even those companies don’t show up in the integrations.

I have 2 CFX3 units myself and use them 24/7 at home except when I go camping or something. It really would be nice to be able to monitor them.

We have one of these CFX3 freezers as well. I might try to reverse engineer the protocol to see if i can cobble something together.

I have 2 CFX3’s, and 2 CFX1’s. I’d be very interested in monitoring all 4 in a single dashboard. Connecting my phone to the app (CFX1 or CFX3) stops the phone from having internet access and only allows connection to one fridge at a time, what a pain!

Yes, I m interested as well, to get my cfx overwatched from ha.

This would be awesome and would be happy to help with testing and tweaking. I have CFX in the back of the ute and HA in the caravan.

Hi there, did anyone ever figure out / publish details of the CFX interface here?

Thanks,

Hi there,

I am interested using ESPHome with BLE-proxy to receive and read the bluetooth data from my Dometic CFX2 45 fridge.
The proxy works already for BLE-tracking my phone (for homezone in/around my van) and for victron smart solar and orion ts charger very nice :smiling_face_with_three_hearts:

On my wish (todo) list:

  • Wattstunde Nova BLE LifePo4 battery information
  • Dometic CFX2 BLE control and information
  • Victron SmartSolar Control of the Load Output through ble

best wishes
Nig

While its an old post, here’s a link to ESP Home repo I built, confirmed operational CFX3 fridges - GitHub - andrewbackway/esphome-dometic_cfx_ble: ESPHome External Component to control and monitor Dometic CFX fridges over BLE using the native ESP-IDF BLE stack.

Nice! I will definitely give this a shot. Thank you.
I just got into home assistant this weekend, so I’m learning and waiting on esp32 to arrive to setup BT proxy and whatever else I can think to put in it.
