IFTTT不発事故に起因する2021年版AirconShutdownの善後策。

これまではTwitter経由のIFTTTで家電リモコンとSwitchBotを制御していたところ、2022年版IRKitでは直接APIを叩くようにできたので、SwitchBotもSwitchBot Open APIを叩くことに。

https://api.switch-bot.com/v1.0/devices//commands

というRESTエンドポイントに制御データをPOSTする枠組み。で指定する対象装置は

curl --request GET 'https://api.switch-bot.com/v1.0/devices' \
--header 'Authorization: 認証トークン' \
--header 'Content-Type: application/json; charset=utf8'

で一覧を取得できる。なお、認証トークンはSwitchBotをHub経由でAPIから操作するに倣い、SwitchBotアプリの「開発者向けオプション」から取得できる。

ちなみに、エアコンの制御データのパラメータは

deviceType	Air Conditioner
commandType	command
Command	setAll
command parameter	{temperature},{mode},{fan speed},{power state} e.g. 26,1,3,on
Description	the unit of temperature is in celsius; modes include 1 (auto), 2 (cool), 3 (dry), 4 (fan), 5 (heat); fan speed includes 1 (auto), 2 (low), 3 (medium), 4 (high); power state includes on and off

…となっているので、、エアコン停止用の

{ "command": "setAll", "parameter": "25,1,1,off", "commandType": "command"}

というデータを"switchbot_aircon_off.json"というファイルにして

#!/bin/bash

BASEPATH=$(dirname $0);

SWITCHBOT_API="https://api.switch-bot.com/v1.0"
SWITCHBOT_TOKEN="90edf....3431"

hdr_auth="Authorization:${SWITCHBOT_TOKEN}"
hdr_type="Content-Type: application/json"
# BODY="@${BASEPATH}/switchbot_aircon_off.json"
BODY='{"commandType": "command", "command": "setAll", "parameter": "25,1,1,off"}'

AIRCON_1F="01-2020XXXXXXXX-32" # 1F
AIRCON_2F="01-2020YYYYYYYY-52" # 2F
AIRCON_3F="01-2020ZZZZZZZZ-82" # 3F

for DEVICE_ID in $AIRCON_1F $AIRCON_2F $AIRCON_3F;
do
URL="${SWITCHBOT_API}/devices/${DEVICE_ID}/commands"
curl "${URL}" \
--silent -O /dev/null \
-H "${hdr_auth}" -H "${hdr_type}" \
-X POST -d "${BODY}"
done

というスクリプトを回せばエアコン3台が順次停止になる運びだ。

昨年6月に復活したIRKitの不調具合が加速してきた折、3,980円であらゆる家電をIoT化。Matterリモコン「Nature Remo nano」というニュースで、一つ前世代のNature Remo miniを調達してたのを思い出し、慌てて投入。

Nature Developer PageによるとIRKitのような「Local API」も公開されているらしい。

yano@haswell:~/smarthome$ avahi-browse -t _remo._tcp
+ vlan.3 IPv6 Remo-mini5CD364 _remo._tcp local
+ vlan.3 IPv4 Remo-mini5CD364 _remo._tcp local

Remo-mini5CD364.local 10.20.199.127
yano@haswell:~/smarthome$

IRKitと同じ流儀で

yano@haswell:~/smarthome$ REMO_TCP=$(avahi-browse -t _remo._tcp);
yano@haswell:~/smarthome$ ADDR_REMO=$(avahi-resolve -n $(echo $REMO_TCP | awk '{print $4"."$6}') | awk '{print $2}')

と、リモコンのデータも取得できるようだ。
