Here’s what it looks like on my frontend:
I tried using room-assistant and it worked pretty well for the last two years until one of my pi 3’s wifi module broke.
I am using room presence to decide whether to turn off the devices in the room if there are no motion for x amount of time and room presence is equal to 0.
Here’s what I am using:
• Amazfit’s GTR 2e / GTS2 / BIP S (Mi band will also work)
• Tasker or HA companion app on Android
• Notify for amazfit (need the intents for heartbeat/notWearing) - this is to determine if the watch is on hand
• ESP 32s for each room
Steps:
- Configure amazfit on notify app.
a. Enable amazfit discoverable
b. Enable tasker integration for the intents
c. Configure heart monitor:
i. interval - 5 mins
ii. Heart monitor mode - use notify and amazfit device
- Configure tasker or companion app to catch the following intents:
(com.mc.miband.tasker.notWearing & com.mc.miband.heartRateGot)
a. On HA companion app (recommended so it will work with public/private URL)
Go to settings > companion app> manage sensors> Last update trigger
Add the two intents
b. On Tasker (you will need MQTT plugin + external&internal MQTT server):
i. Create intent received profile for the two intents above.
ii. Point the profile to execute tasks that passes the intent's value e.g.
1) Heartrate
a) Topic: user1/watch/hr
b) Payload: %value
2) NotWearing
a) Topic: user1/watch/onhand
b) Payload: false
c. Configure mqtt sensor:
- name: "user1_watch_heartrate" unique_id: user1_watch_heartrate state_topic: "user1/watch/hr" value_template: "{{ value|int(0)}}" unit_of_measurement: "bps" state_class: measurement
d. Configure mqtt binary sensor:
- name: "user1_watch_onhand" unique_id: user1_watch_onhand state_topic: "user1/watch/onhand" payload_on: "true" payload_off: "false"
e. Automations:
i. watch_onhand_true:
alias: watch_onhand_true id: watch_onhand_true mode: parallel trigger: - platform: state entity_id: 'sensor.user1_watch_heartrate' id: user1 condition: condition: or conditions: - condition: and conditions: - condition: state entity_id: binary_sensor.user1_watch_onhand state: 'off' - condition: trigger id: user1 action: - choose: - conditions: - condition: trigger id: user1 sequence: - service: mqtt.publish data: topic: "user1/watch/onhand" payload: "yes" retain: true
ii. watch_onhand_false:

iii. watch_heartrate:

- ESP32s
a. Per each room / esp32, Configure the input_number for RSSI strength at 1meter:
esphome_measuredpower_rp_livingroom:
1) Min: -99
2) Max: -1
3) Unit of measurement: dB
b. Templates:
notes: name of ble rssi entity is rp__user1watch
i. persons_livingroom:
persons_livingroom: unit_of_measurement: person/s value_template: > {% set room = 'livingroom' %} {% set ns = namespace(total=0,notonhand=0) %} {% for state in states['sensor'] %} {% if state.entity_id.startswith('sensor.rp_') and state.state==room %} {% set ns.total = ns.total + 1 %} {% endif %} {% endfor %} {% if states.binary_sensor.user1_watch_onhand.state=='off' and states.sensor.rp_user1.state==room %} {% set ns.notonhand = ns.notonhand + 1 %} {% endif %} {% if states.binary_sensor.user2_watch_onhand.state=='off' and states.sensor.rp_user2.state==room %} {% set ns.notonhand = ns.notonhand + 1 %} {% endif %} {% if states.binary_sensor.user3_watch_onhand.state=='off' and states.sensor.rp_user3.state==room %} {% set ns.notonhand = ns.notonhand + 1 %} {% endif %} {{ ns.total - ns.notonhand}}
ii. rp_user1 (note: you can set the farthest distance of the room between your device and esp32 on the ns namespace as input_number too)
rp_user1: value_template: > {% set device = 'user1watch' %} {% set ns = namespace(kitchen=5,livingroom=8,entertainmentroom=6.5,laundry=5,masterbedroom=6,home=0,rp=[], min=[]) %} {% for state in states['sensor'] %} {% if state.entity_id.startswith('sensor.rp_') and state.entity_id.endswith(device+'_distance') %} {% set room = state.entity_id|replace('sensor.rp_','')|replace('_'+device+'_distance','') %} {% if room=='kitchen' and state.state|float(20) <= ns.kitchen %} {% set ns.rp=ns.rp + [state.entity_id] %} {% set ns.min=ns.min + [state.state|float(20)] %} {% elif room=='kitchen' and state.state|float(20) > ns.kitchen and state.state!='unknown' and state.state!='unavailable' %} {% set ns.home=ns.home|int(0)+1 %} {% elif room=='livingroom' and state.state|float(20) <= ns.livingroom %} {% set ns.rp=ns.rp + [state.entity_id] %} {% set ns.min=ns.min + [state.state|float(20)] %} {% elif room=='livingroom' and state.state|float(20) > ns.livingroom and state.state!='unknown' and state.state!='unavailable'%} {% set ns.home=ns.home|int(0)+1 %} {% elif room=='entertainmentroom' and state.state|float(20) <= ns.entertainmentroom %} {% set ns.rp=ns.rp + [state.entity_id] %} {% set ns.min=ns.min + [state.state|float(20)] %} {% elif room=='entertainmentroom' and state.state|float(20) > ns.entertainmentroom and state.state!='unknown' and state.state!='unavailable' %} {% set ns.home=ns.home|int(0)+1 %} {% elif room=='laundry' and state.state|float(20) <= ns.laundry %} {% set ns.rp=ns.rp + [state.entity_id] %} {% set ns.min=ns.min + [state.state|float(20)] %} {% elif room=='laundry' and state.state|float(20) > ns.laundry and state.state!='unknown' and state.state!='unavailable' %} {% set ns.home=ns.home|int(0)+1 %} {% elif room=='masterbedroom' and state.state|float(20) <= ns.masterbedroom %} {% set ns.rp=ns.rp + [state.entity_id] %} {% set ns.min=ns.min + [state.state|float(20)] %} {% elif room=='masterbedroom' and state.state|float(20) > ns.masterbedroom and state.state!='unknown' and state.state!='unavailable' %} {% set ns.home=ns.home|int(0)+1 %} {% endif %} {% endif %} {% endfor %} {% if ns.min==[] and ns.home!=0 %} home {% elif ns.min==[] and ns.home==0 %} not_home {% else %} {% set min_d = min(ns.min) %} {% set min_di = ns.min.index(min_d) %} {{ ns.rp[min_di]|replace('sensor.rp_','')|replace('_'+device+'_distance','')}} {% endif %}
c. ESP32 config:
notes:
1) I’ve splitted this so I just need to configure common_sensor_bletracker.yaml if I wanted to change filters on all esp32 devices.
2) You also need to create components/just_Esp_bt.h and copy secrets.yaml to common/
3) Regarding filters, I tested sliding_moving_average and mean but the update is very slow. Throttling average gives me somewhat accurate and it shows unknown if the device is not within esp32 bluetooth range
