Hive App Not Working? Here's (Probably) Why And How to Fix

Struggling to get your Hive back alive? It's a common issue (which, isn't really a good thing, is it?). Let's try to resuscitate your home's smart heating, and see why it's acting dumb.

You bought a Hive thermostat to make your life easier. You imagined effortless heating control from your phone, adjusting temperatures while still in bed. But now, the Hive app isn’t working, and instead of convenience, you’re wanting to stab really sharp pins in to your face.

If you’re sick of refreshing the app and watching nothing happen, you’re in the right place. Below, we’ll break down exactly why your Hive thermostat or app isn’t working and how to fix it, without needing to tear your hair out or smash the thermostat off the wall.

Note: If your heating issues go beyond Hive, maybe it’s time for a new boiler installation.

Common Reasons Why Your Hive App Isn't Working

Before we even start, let’s be clear, there are a number of reasons why your Hive isn’t playing with your balls.

But, before troubleshooting, your Hive app or thermostat may be working as intended, but, due to the insanely silly amounts of modes and settings, perhaps it’s just set up wrong.

Here’s a quick and easy video on how to use a Hive thermostat, to start:

Still not right? thought so.

Let’s run over the most common ones below, and see where we go, eh?

1. Hive App Not Working on iPhone or Android

Hive Not Working iPhone or Android

The Hive app refusing to open, crashing, or freezing on your phone is a top complaint and plagues many a user. Nine point 6 times out of ten, this is due to an outdated app version, a software bug, or your phone simply throwing a tantrum (…before you throw it on the window).

So, here’s some quick pointers and fixes if your apps having a paddy:

  • First, check for app updates
    Open the App Store (iPhone) or Google Play Store (Android) and update Hive.

  • Clear the Hive app cache
    On Android, go to Settings > Apps > Hive > Storage > Clear Cache.
    On iPhone, simply uninstall and reinstall the app.

  • Restart your phone
    Sounds basic, but it fixes a lot of issues.

  • Disable VPNs or ad blockers (rare)
    If you have a VPN, try disabling it. They can interfere with app connectivity.

If your boiler is the ones that’s acting up, it can sometimes be pressure loss, so, here’s why your boiler might be losing pressure.

2. Hive Heating Not Working But Hot Water Is

If your hot water works, but the heating won’t turn on, the thermostat might not be talking to the boiler properly. This is annoying, like getting a spider web off your face, but fixable.

A bit like Boris’ banter during lockdown, this typically usually a breakdown in communication

Here’s how get your Hive app and boiler chatting again:

  • Check the heating mode
    Open the Hive app and ensure heating isn’t stuck on ‘Off’.

  • Restart the Hive Hub
    Unplug it for 30 seconds, then power it back on.

  • Manually set the thermostat to full heat
    If the boiler ignores it, the issue might be with the boiler, not Hive.

  • Bleed your radiators
    If they’re staying cold, airlocks could be stopping heat from circulating.

If you think the Hive is working okay, but the radiators aren’t warming up, here’s how to fix a cold radiator.

3. Hive Thermostat Working But Not the App

If the thermostat is working fine manually but refuses to respond in the app, the issue is likely a Hive server outage or a dodgy connection.

Here’s some quick check-points:

  • Check Hive’s service status
    Visit Hive’s status page to see if their servers are down.

  • Restart both the thermostat and Hive Hub
    A quick reboot can refresh the connection.

  • Check if your app needs an update
    Old versions can cause syncing failures.

4. Hive Thermostat Stuck on Searching

A Hive thermostat that won’t connect and stays on “Searching” is usually suffering from a lost link to the Hive Hub. If it can’t reconnect, it’s about as useful as a paperweight.

Without a connection to the Hive Hub, Your Hive app and smart thermostat will be in a state of uselessness forever and ever

Here’s some quick steps to reconnect your Hive’s back up:

  • Restart the thermostat
    Remove and reinsert the batteries (if applicable).

  • Reboot the Hive Hub
    Unplug it, wait a minute, plug it back in (believe it or not, this genuinely works)

  • Check WiFi strength
    A weak signal can cause connection drops.

  • Re-pair the thermostat
    In the Hive app, navigate to settings and follow the steps to reconnect.

5. Hive App Schedule Not Working

If your heating is ignoring your schedule or turning on at random times, there’s likely a syncing issue between the thermostat and the Hive app.

Try get your Hive back alive, by:

  • Check the app’s time zone settings
    A mismatch can cause scheduling confusion.

  • Ensure ‘Schedule Mode’ is activated
    If it’s on ‘Manual,’ your set schedule won’t run.

  • Delete and recreate your heating schedule
    If it’s corrupted, resetting it can restore function.

  • Restart the Hive Hub
    It may need a fresh connection to sync properly.
