Support switch and binary_sensor as int

[cristianchelu]

The specs for Smart Pet Food Feeder (mmgg.feeder.fi1) use a uint8 0 ~ 1 value instead of a boolean true ~ false to read or control the status of some properties, for example SIID 6 PIID 1 (Child Lock), SIID 3 PIID 1 (Indicator Lights), SIID 4 PIID 8 (Food outlet door) and SIID 4 PIID 9 (Food storage cover).

I'm not really sure if this should be handled as a configuration option in this component or if it's better to leave it as a combination of filters in the esphome config (or I missed some obvious solution, in which case I'm sorry for the time waste!).

I have the following configuration:

binary_sensor:
  - platform: "miot"
    miot_siid: 4
    miot_piid: 9
    name: "Top Lid"
    device_class: opening
  - platform: "miot"
    miot_siid: 4
    miot_piid: 8
    name: "Food door"
    device_class: opening

switch:
  - platform: "miot"
    miot_siid: 3
    miot_piid: 1
    name: "Indicator lights"
    icon: mdi:lightbulb
    entity_category: config
  - platform: "miot"
    miot_siid: 6
    miot_piid: 1
    name: "Child Lock"
    icon: mdi:lock
    inverted: yes
    entity_category: config

For the Child lock switch, here's a verbose log for triggering it via the mcu_command service with command: "set_properties 6 1 0"

[19:14:19][D][miot:125]: Queuing MCU command 'set_properties 6 1 0'
[19:14:19][V][miot:091]: Received MCU message 'get_down'
[19:14:19][V][miot:174]: Sending reply 'down set_properties 6 1 0' to MCU
[19:14:19][V][miot:091]: Received MCU message 'result 6 1 0'
[19:14:19][V][miot:174]: Sending reply 'ok' to MCU
[19:14:19][V][miot:091]: Received MCU message 'properties_changed 6 1 0'
[19:14:19][V][miot.switch:011]: MCU reported switch 6:1 is: OFF
[19:14:19][V][miot:174]: Sending reply 'ok' to MCU

The inverted switch is now on in the UI, and toggling it back off results in the following verbose log

[19:16:18][D][switch:016]: 'Child Lock' Turning OFF.
[19:16:18][V][miot.switch:017]: Setting switch 6:1 ON
[19:16:18][D][miot:125]: Queuing MCU command 'set_properties 6 1 true'
[19:16:18][D][switch:055]: 'Child Lock': Sending state OFF
[19:16:18][V][miot:091]: Received MCU message 'get_down'
[19:16:18][V][miot:174]: Sending reply 'down set_properties 6 1 true' to MCU
[19:16:19][V][miot:091]: Received MCU message 'result 6 1 0'
[19:16:19][V][miot:174]: Sending reply 'ok' to MCU
[19:16:19][V][miot:091]: Received MCU message 'properties_changed 6 1 0'
[19:16:19][V][miot.switch:011]: MCU reported switch 6:1 is: OFF
[19:16:19][D][switch:055]: 'Child Lock': Sending state ON
[19:16:19][V][miot:174]: Sending reply 'ok' to MCU

For the read-only top lid state, here's the verbose log when I physically open it:

[19:18:33][V][miot:091]: Received MCU message 'properties_changed 4 8 1'
[19:18:33][V][miot.binary_sensor:011]: MCU reported sensor 4:8 is: OFF
[19:18:33][V][miot:174]: Sending reply 'ok' to MCU

and when I physically close it back:

[19:19:35][V][miot:091]: Received MCU message 'properties_changed 4 8 0'
[19:19:35][V][miot.binary_sensor:011]: MCU reported sensor 4:8 is: OFF
[19:19:35][V][miot:174]: Sending reply 'ok' to MCU

How annoying... I'll see how we can support that without making the code too ugly :)

Can you try with that ^ commit? You can then use e.g.:

binary_sensor:
  - platform: "miot"
    miot_siid: 4
    miot_piid: 9
    miot_true: "1"
    miot_false: "0"
    name: "Top Lid"
    device_class: opening

(and the same for switches)

Confirmed both switch and binary_sensor are reported and controlled well with the new commit & configuration. Thanks!

[dhewg]

Nice, thanks for the confirmation!
