I’m trying to use the following ESP32 MQTT code I found:
To allow home assistant to control my GE Opal Ice Maker over BLE. The two problems I’m having as a super noob to this is how do I convert this code from JSON to the YAML needed for ESPHome and how do I find the MAC Address of my BLE since it only broadcasts a UUID?
Thanks in advance!
It doesn’t work that way. ble2mqtt is it’s own program and not compatible with esphome.
Got it, thank you. I wish I could get this to work in esphome because I’m having a ridiculous time trying to flash this now.
So you would start here:
From the JSON linked:
"characteristics" : {
"definitions": {
"79994230-4b04-40cd-85c9-02dd1a8d4dd0": {
"name": "make-ice",
"types": ["uint8"]
},
"097a2751-ca0d-432f-87b5-7d2f31e45551": {
"name": "make-state",
"types": ["uint8"]
},
"5bcbf6b1-de80-94b6-0f4b-99fb984707b6": {
"name": "ice-bin-state",
"types": ["uint8"]
},
"37988f00-ea39-4a2d-9983-afad6535c02e": {
"name": "night-light",
"types": ["uint8"]
}
These are various functions that have been decoded from the ice maker. So 097a2751-ca0d-432f-87b5-7d2f31e45551 is the make-state.
You can see here: BLE Client Sensor — ESPHome how you would use these.
So an example using the data from the JSON would be:
esp32_ble_tracker:
ble_client:
- mac_address: MACADDRESS
id: ice_maker
sensor:
- platform: ble_client
ble_client_id: ice_maker
name: "Make State"
service_uuid: '3e6763c5-9429-40cc-909e-bebf8c7487be'
characteristic_uuid: '097a2751-ca0d-432f-87b5-7d2f31e45551'
- platform: ble_client
ble_client_id: ice_maker
name: "Ice Bin State"
service_uuid: '3e6763c5-9429-40cc-909e-bebf8c7487be'
characteristic_uuid: '5bcbf6b1-de80-94b6-0f4b-99fb984707b6'
- platform: ble_client
ble_client_id: ice_maker
name: "Night Light Status"
service_uuid: '3e6763c5-9429-40cc-909e-bebf8c7487be'
characteristic_uuid: '37988f00-ea39-4a2d-9983-afad6535c02e'
That should get you going along the right path.
I got this working! Thank you. Is there anyway to send the “make-ice” command, or only poll the sensor states?
This is what I have now:
esp32_ble_tracker:

then:

output:

require_response: false
switch:

output: make_ice
It works fine until I add the “output” and “switch” blocks. Then it can’t even seem to connect. This is the log dump I get:

Thanks for getting this started over a year ago. I think I got it working, with switches for the light and maybe the ice making function. The problem is the Opal wants to pair, so I needed to figure out a way to force it to pair on connect. It can only be paired with one device at a time. Maybe I’ll try to make a proxy version of this, but below is my YAML.Not sure if the passkey is required, but I left it in. I think the pair() command during the connect was the missing link.
