HeatMiser NeoHub rebooter

Hi! This repository contains a Bash shell script that, when ran on a daily basis, reboots Heatmiser's NeoHub (v2) to keep the legacy API available that normally stops listening after a 48 hour idle period. More specifically, this keeps the Apple HomeKit integration working.

In short, the script:

• Checks connectivity to the NeoHub and inform through push notification if it fails to connect
• Reboots the NeoHub
• Verifies the reboot succeeded by checking the uptime

Prerequisites

• A Linux OS that supports scheduled execution of shell scripts, e.g. cron.
• A recent version of NodeJS. It's recommended to use a Node version switcher like nvm.
• The script currently depends on the Pushover web+app solution for easy push notification delivery. Specify the user and app token in the top config part of the script.

Install instructions

• First, run npm install to install wscat - a Node module that supports connecting to websockets and reading/writing them.
• Configure the script by setting:
  • HUB_IP
  • HUB_TOKEN
  • PUSHOVER_API_TOKEN
  • PUSHOVER_USER_KEY
• Run crontab -e to edit your crontab.
• Add a line defining the PATH envvar; ensure node / wscat can be found on this path.
• Add a line defining the SHELL to be bash: SHELL=/bin/bash
• Add the actual cron definition. For a nightly run at 01:00 e.g:
  • 0 1 * * * /path/to/restart_neohub.sh >> /logpath/restart_neohub.log

Now, verify success the next morning. A successful run looks like:

27-01-2024 01:00:01 - Running restart_neohub.sh
27-01-2024 01:00:01 - Successfully sent restart command to the NeoHub
27-01-2024 01:00:01 - Sleeping for 5 minutes before checking for successful reboot
27-01-2024 01:05:15 - Successfully restarted the NeoHub. Current uptime is 160 sec. which is less than 900 (15 min.)

That's it!
