Hive not controlling the boiler: three links that can break separately
A Hive system has an app, a hub, a thermostat, and a receiver. Losing any one of them looks the same from the app, and they are fixed differently.
What this means
A Hive installation is a chain: the app talks to Hive, Hive talks to the hub, the hub talks to the thermostat and the receiver, and the receiver switches the boiler. A break anywhere along that chain presents in the app as the heating not responding, and the repair depends entirely on where the break is.
Equipment and model context
Hive heating control systems using a hub, a thermostat, and a boiler receiver as described in Hive support
- Hive Active Heating
- Hive Thermostat Mini
- Hive Hub and receiver
Hive has shipped several generations of hub, thermostat, and receiver with different radio arrangements and different indications. The Hive support material for the products you actually own is the reference, and the position of a break is established from the devices rather than from the app alone.
What you may notice
- The app reports the system as offline, or commands sent from it produce no change at the boiler.
- The thermostat itself shows a signal or connection indication rather than a temperature.
- The heating can still be operated from the boiler receiver even though the app cannot reach it.
Likely causes
- The internet connection or the hub can lose its link, which cuts the app from the system while the local devices still work.
- The radio link between the hub, the thermostat, and the receiver can be interrupted by distance, building fabric, or interference.
- The receiver can lose its supply or its connection to the boiler, which stops the heating regardless of everything upstream.
Diagnostic paths
The receiver can still turn the heating on manually
Operating the boost or manual control on the receiver itself produces heat, even though the app cannot make anything happen.
That places the break upstream of the receiver. The boiler and the receiver connection are working, so the investigation moves to the radio link or the hub.
Nothing happens even at the receiver
Manual operation at the receiver produces no response from the boiler at all, whatever the app or the thermostat shows.
Check whether the receiver has power and whether the boiler works from any other control. A dead link at this end is a heating installation question rather than a connectivity one.
Everything works but only locally
The thermostat controls the heating in the house while the app reports the system unreachable from outside.
Treat it as an internet or account matter rather than a heating fault. Local control surviving means the hub-to-devices link and the boiler connection are intact.
Smart heating replaces a single pair of wires with a chain of four connections. The convenience comes from that chain, and so does the failure mode, because any one link going down produces the same symptom at the far end.

| Symptom | Break location | Who resolves it |
|---|---|---|
| App offline, local control works | Internet or account link | The owner or the broadband provider |
| Thermostat lost, receiver works | Radio link between devices | Repositioning or Hive support |
| Receiver manual works, nothing else | Upstream of the receiver | Hive support |
| Receiver manual does nothing | Receiver supply or boiler connection | A heating engineer |
The manual control at the receiver is the diagnostic
Every Hive installation keeps a way to operate the heating at the receiver itself, and it exists precisely for the situation where the rest of the chain is unavailable. It is also the best test an occupant can run, because it splits the problem in half in about ten seconds.
Heat arriving means the boiler, the receiver, and the wiring between them are all fine, and the fault sits somewhere in the radio, the hub, or the internet. No heat means the opposite, and the conversation to have is with a heating engineer rather than with a support line.
Why cold houses and connectivity faults arrive together
Radio links are affected by the building around them, and buildings change. A hub that reached a receiver across a hallway may struggle after a new appliance, a rearranged room, or a different broadband router is installed in a different place. None of that is obvious, and the symptom arrives as heating that has stopped responding rather than as a radio complaint.
Recording what changed in the house in the days before the fault is worth more here than on almost any equipment fault, because the answer is frequently something nobody connected to heating at the time. The thermostat wiring explainer covers how a receiver connects to a heating appliance, and the combi no hot water reference covers what to check when the boiler itself is the suspect.
What to give the technician
Say which devices respond and which do not, whether the receiver operates the boiler manually, whether local thermostat control still works, and what changed in the property recently.
Safe homeowner checks
- Operate the manual or boost control on the receiver and note whether the boiler responds, which splits the fault in half immediately.
- Check whether the thermostat still controls the heating locally even if the app cannot reach the system.
- Note anything that changed in the house recently: a new router, a moved hub, an appliance, or building work.
Is a reset appropriate?
Restarting the hub and the router restores an internet or account link and does nothing for a radio or wiring break. Establish where the break is with the receiver test before restarting anything.
When to call a technician
- Wiring between a receiver and a heating appliance carries mains voltage on United Kingdom installations and is not an owner task.
- A boiler that does not respond to manual operation at the receiver is a heating fault rather than a connectivity one, and it belongs to a Gas Safe registered engineer.
Questions people ask about this
Can I still heat the house if Hive is offline?
The receiver keeps a manual or boost control that operates the boiler independently of the app and the hub. It exists for exactly this situation and it is also the fastest way to locate the fault.
Why did Hive stop working after I changed my broadband?
A new router changes both the internet link and, if the hub moved with it, the radio path to the other devices. Either can produce the same symptom, which is why the receiver test comes first.
Is a Hive fault a job for a heating engineer?
Only when the receiver cannot operate the boiler manually. Everything upstream of that is connectivity, and sending a heating engineer to an internet fault costs a visit that changes nothing.
