Hive App Not Working? Checks for App, Hub and Thermostat

If the Hive app is not working, first check whether you can still turn the heating on using the thermostat. An app or internet problem is different from a thermostat that has lost contact with its receiver. Identifying which connection has failed avoids unnecessary resets.

Hive app not working but thermostat is

If changing the temperature on the thermostat still controls the heating, use it while you troubleshoot the app. You do not need to replace a working boiler because app control is unavailable. Hive explains this in its guide to controlling heating when offline.

• Check the service: visit Hive service status to see whether there is a reported outage.

• Check your connection: see whether other apps and websites work. Establish whether the problem affects your phone, home broadband or Hive specifically.

• Check the app: close and reopen it, check for an update in your app store, and confirm you are signed into the account associated with your heating.

• Check the hub: note its lights, power and router connection. Follow the guidance for the hub model before resetting or re-pairing devices.

Hive's wireless thermostat troubleshooting guide covers app updates, internet checks and service status. If an outage is reported, repeated factory resets will not fix the service.

How Hive controls your boiler

The thermostat measures room temperature and communicates with the receiver, which switches the heating demand. The hub enables internet and app connectivity. Losing internet access does not automatically mean the local heating controls have stopped working.

Note which device is showing a warning: a hub light, a receiver status light and a thermostat message are different clues. A useful support report includes the exact device, light colour, whether it flashes, and whether the thermostat can still control the heating.

Common Hive Thermostat Problems and How to Fix Them

Below are the issues homeowners experience most often and the steps that usually help.

Hive thermostat not turning the heating on

If your Hive thermostat shows it is calling for heat but the boiler stays off:

• Check if the Hive receiver has a light on.

• Check the heating light on the receiver turns on when you raise the temperature.

• Check the boiler power switch next to the boiler has not been turned off.

• Read any boiler fault code and follow the boiler manufacturer’s instructions before attempting a reset.

• Check the heating target is above the current room temperature and that the intended heating zone is selected.

If the receiver shows no lights at all, there may be a power issue.

No signal between Hive thermostat and receiver

A “No Signal” message means the thermostat has lost contact with its receiver. For a compatible battery-powered model, Hive's first checks include bringing the thermostat near the receiver and removing then reinserting its batteries. Do not apply battery-removal instructions to a hard-wired thermostat.

Use Hive's model-specific No Signal instructions for the correct sequence. If full resetting and pairing becomes necessary, record your schedules first: Hive warns that resetting can erase them. Contact Hive if reconnection repeatedly fails.

Hive thermostat batteries low or empty

Low batteries can stop the thermostat sending commands to your heating.

Signs include:

• Heating works sometimes but not always

• Thermostat screen flickers

• App says “no response”

• Slow reaction to temperature changes

Use the battery type specified for your thermostat model and check polarity. If it does not reconnect, follow the model-specific support guide rather than repeatedly resetting it.

Hive receiver lights flashing or staying off

These meanings refer to the receiver's status light, not the hub. The separate heating and hot-water lights indicate demand.

• Green or blue status: devices are connected.

• Solid red status: the receiver has lost contact with the thermostat.

• No status light: check the receiver's power supply without opening its casing.

• Amber, pink or white: pairing or a pairing timeout; follow the relevant model instructions.

See the device photographs and colour-specific steps in Hive's official receiver troubleshooting guide. A flashing green hub light should be checked using hub guidance, not this receiver list.

The receiver's heating button is a manual on/off control, not a universal connection-reset button. Hive's offline guide explains how to use it temporarily; a dual-channel receiver has separate heating and hot-water controls. Do not open the receiver or work on wiring.

Hive thermostat schedule not working

If the heating is not following the schedule you set:

• Check that the thermostat is in schedule mode, not manual mode.

• Check that boost is not active.

• Check that your app and thermostat have the same time and settings.

• Restart the Hive app.

If the problem persists, record the affected time slot and heating zone before contacting Hive support.

Heating turning on or off at the wrong time

If heating starts unexpectedly or shuts off too early:

• Check if the thermostat is placed near a warm appliance, radiator or window.

• Check the frost protection setting.

• Check any Hive sensors are not overriding the schedule.

A common example is a thermostat placed in direct sun, which makes Hive think the house is warmer than it is.

Hive app not controlling the heating

Follow the app-only checks at the top of this guide if the thermostat still works. If neither app nor thermostat controls the heating, check the receiver lights and any boiler error code instead. A screenshot of the app message and a photo of the receiver can help support distinguish the two situations.

Boiler fires for hot water but not heating

If you have hot water but the heating will not turn on:

• There may be a fault with the motorised valve inside your heating system.

• The Hive receiver may not be sending the heating signal correctly.

• The boiler may not be responding to the heating circuit.

You can check:

• The heating light on the Hive receiver

• That the thermostat is calling for heat

• That boiler power is on

If the boiler fires for hot water only, it often needs a professional to check the valve or wiring.

Quick Checks Most Homeowners Can Do

These steps are safe and often resolve the issue:

Restart only the device that needs it

A restart and a factory reset are different. Begin with the app or affected device rather than resetting the entire system. Use your model's instructions, allow it to reconnect, and check the result before taking the next step. Record schedules before any procedure that removes settings.

Check boiler pressure

If pressure is very low, the boiler may not respond to heating commands.

Read our boiler losing pressure guide and use your boiler manual for the correct range.

Check the isolation switch near the boiler

This switch can be turned off by accident during cleaning or decorating.

Check thermostat placement

Place it in a room where air moves freely and is not near heat sources.

Troubleshooting Table

When You Should Call an Engineer

You should contact a heating engineer when:

• The boiler does not fire after checking connection and power

• The receiver has no lights at all

• There are signs of damaged wiring

• Heating turns on and off within seconds

• The motorised valve may be stuck or faulty

• There are scorch marks: stop using the affected equipment and seek professional help

Do not attempt to open or repair boiler wiring. If you suspect a gas leak, leave the property and call the gas emergency service from a safe place; do not operate electrical switches or use a flame.

Preventing Future Hive Heating Problems

Preventing issues is often simple:

• Replace batteries when needed, using the specified type
  Weak batteries create many common Hive faults.

• Keep the Hive hub in an open location
  Avoid cupboards or behind the TV.

• Update the Hive app and firmware
  This helps with stability and connection.

• Check boiler pressure regularly
  Low pressure stops heating from working properly.

• Place the thermostat in a suitable location
  Avoid radiators, windows, ovens or direct sunlight.

• Service your boiler yearly
  A well maintained boiler responds better to smart controls.

Final Thoughts on Fixing Hive Heating Problems

Most Hive heating problems come from simple connection or power issues.

Batteries, hub resets and receiver checks often restore heating quickly.

If the boiler does not fire after these steps, or the receiver shows no lights, an engineer should take over.
