rsync version 3.1.3 protocol version 31
Copyright (C) 1996-2018 by Andrew Tridgell, Wayne Davison, and others.
Web site: http://rsync.samba.org/
Capabilities:
64-bit files, 64-bit inums, 32-bit timestamps, 64-bit long ints,
socketpairs, hardlinks, symlinks, IPv6, batchfiles, inplace,
append, ACLs, xattrs, iconv, symtimes, prealloc
rsync comes with ABSOLUTELY NO WARRANTY. This is free software, and you

General Public Licence for details.
rsync is a file transfer program capable of efficient remote update
via a fast differencing algorithm.
Usage: rsync [OPTION]... SRC [SRC]... DEST
or rsync [OPTION]... SRC [SRC]... [USER@]HOST:DEST
or rsync [OPTION]... SRC [SRC]... [USER@]HOST::DEST
or rsync [OPTION]... SRC [SRC]... rsync://[USER@]HOST[:PORT]/DEST
or rsync [OPTION]... [USER@]HOST:SRC [DEST]
or rsync [OPTION]... [USER@]HOST::SRC [DEST]
or rsync [OPTION]... rsync://[USER@]HOST[:PORT]/SRC [DEST]
The ':' usages connect via remote shell, while '::' & 'rsync://' usages connect
to an rsync daemon, and require SRC or DEST to start with a module name.

Raspberry PiのBootオプション変更（NASマウントタイミング変更）
Raspberry PiのBoot Option「Wait for Network at Boot Choose whether to wait for network」を変更します。「raspi-config」を用いて、設定を行います。
@raspberrypi:~ $ sudo raspi-config
3 Boot Options Configure options for start-up を選択
B2 Wait for Network at Boot Chose whether to wait for network connection を選択
<Yes> を選択
<Ok> を選択
/etc/rc.localに３秒Sleep後マウント
上記の設定後も、起動・再起動時の自動マウントが実行されませんでした。 シスログ（/var/log/syslog）を確認したところ、やはり起動時のマウント時にNASへのネットワークマウントが失敗しておりました。 mount.nfs: Network is unreachable
Jul 9 06:36:22 raspberrypi rpc.mountd[473]: Version 1.3.3 starting
Jul 9 06:36:23 raspberrypi mount[489]: mount.nfs: Network is unreachable

Jul 9 06:36:23 raspberrypi systemd[1]: Failed to mount /mnt/synology.
よって、/etc/rc.localに３秒のスリープとマウントコマンドを追加しました。 sleep 3 sudo mount -t nfs 192.168.0.100:/volume1/raspberry /mnt/synology
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.

#
# By default this script does nothing.
# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
printf "My IP address is %s\n" "$_IP"
fi
#After Sleep 3, then execute a mount command
sleep 3
sudo mount -t nfs 192.168.0.100:/volume1/raspberry /mnt/synology

準備したPHPファイルより「@GOOGLE_HOME_1@ http://192.168.0.200:9081 などgoogle home notifier向けのURL」に設定したgoogle home notifier経由で対象スピーカーよりアナウンスを実施します。 夜間に音を出したくないので、checkTime($startTime, $endTime)関数を用いて、実行時の時間を確認しています。
Google Home Notifierは、テキストをgoogle-tts-apiを用いて、音声変換を実施しております。十分に内容は把握できますし、実利用には支障はないのですが、HOYA社より優れたWeb APIが公開されているので、HOYA社のVoice Text Web APIを用いた音声に変更を実施します。HOYA株式会社 VoiceText Web API
