How do I control my pellet stove remotely?

From anywhere, on WiFi or mobile data: your phone doesn't need to be at home, since the command goes through the module's online service. The stove needs to be powered on, its module linked to your router, and an app installed on your phone. For a stove fitted with a Fumis WiRCU module, connecting to Flam takes about five minutes.

Is my stove WiFi compatible?

It is if its circuit board accepts a connectivity module, either already fitted or offered as an option. The brand alone doesn't tell you: two models from the same brand can have different electronics, and the board sometimes changes from one production year to the next. Ask the manufacturer or your installer, with the full model reference and the stove's serial number.

Which pellet stove can connect to an app?

Many manufacturers offer a connectivity module, either fitted as standard or as an option, each with its own online service and app. A stove fitted with one can therefore be controlled with its manufacturer's app, or the module manufacturer's app. An independent app only works with the modules whose service it knows: for Flam, that's the Fumis WiRCU today.

What happens if the internet connection drops?

The stove keeps its last state: lit, it keeps heating; off, it stays off. The free scheduler's slots, stored on the stove, keep running. Flam Pilot's slots, decided online, don't start. If Eco+ was active, the stove's own eco mode stays switched off: the stove modulates its flame without stopping on its own until the connection comes back.

WiFi pellet stove: the module and the app you need

To control a pellet stove from your phone, you need two things: a WiFi module wired into the stove's circuit board, then an app. Your stove may already have the first one without you knowing it. What decides this isn't the brand on its own, it's that module. This guide helps you check what you've got, find out what you need if you don't have it, and understand what an app can do once you're connected.

How does a pellet stove connect to WiFi?

With a WiFi module like the WiRCU, the app doesn't talk to the stove directly. The chain has three links:

The connectivity module, wired into the stove's circuit board and linked to your router over WiFi.
The module manufacturer's online service, which receives the stove's status and passes on your commands.
The app, on your phone, which talks to that service.

Three practical consequences follow. Without a module, no app can reach the stove remotely, whichever one it is. Compatibility depends on the module fitted, not just on the stove's brand. And if the online service goes down, every app that relies on it goes blind at the same time, the manufacturer's own app included, and Flam too.

Does your stove already have a module?

Three checks, from the most reliable to the quickest:

Look for the module's label. A Fumis WiRCU module carries a label with a MAC address (twelve characters) and a PIN code: these are its connection credentials. Where it sits varies from one stove to another; your model's manual says where.
Check the manual or the spec sheet. Look for the words WiFi, module, app or remote control, and any mention of it being an option.
Ask yourself if you already control it remotely. If you can light your stove from the manufacturer's app, it has a module. The label tells you which one.

The Fumis WiRCU module: which brands?

Fumis makes electronics for pellet stoves, and its boards are fitted in stoves from several brands. Its WiFi module is called the WiRCU. Whatever the stove's brand, a WiRCU goes through the same online service and connects with the same two credentials: the MAC address and PIN code on its label.

Stoves from the following brands, when fitted with a WiRCU module, can be controlled with Flam today:

Two things worth noting. Not every model from these brands has a WiRCU fitted: it's the label that counts, not the logo on the front. And other brands use other modules and other online services, which Flam doesn't control today. Model details are on the compatible pellet stoves page.

No module on your stove: can you add one?

It depends on its electronics, and there are three cases.

The electronics have a module as an option. This is the simplest case: the manufacturer or your installer can tell you which module fits your model.

The electronics only accept a wired box. Some stoves only connect through a box made by their manufacturer, wired by cable to the board. Flam can't reach these boxes today: ask the stove's manufacturer about the app that goes with them.

A so-called "universal" module. A module that plugs into the input meant for a room thermostat lets you light and switch off the stove remotely. It does nothing more: it doesn't set the target temperature or the power, and it can't tell if the stove has broken down or run out of pellets. Flam doesn't use these.

What can the manufacturer's app do?

Several brands fitted with a WiRCU have their own app: PelletControl for Austroflamm, Haas+Sohn for Haas+Sohn, Heta Remote for Heta. We haven't found one under the Eco Spar or Prity name: Fumis publishes an app under its own name, built for its WiRCU modules. These apps cover the essentials: lighting, switching off, setting the target temperature and power, scheduling the stove's own timers. Depending on the app, some settings, like the eco mode, are only available on the stove itself.

They make the stove controllable remotely, and they carry out your settings: the stove lights at the time you scheduled, whatever the cold outside.

Which app for a WiFi-connected pellet stove?

The manufacturer's app is enough to control the stove remotely. Flam is a different, independent one: it goes through the same online service, with the same two credentials, the module's MAC address and PIN code. It never asks for a manufacturer account password. The setup guide covers the connection in detail.

Free, with no time limit:

lighting, switching off, setting the target temperature and power, checking the stove's status;
switching on the stove's own eco mode from the app;
scheduling the week on the stove's own timers: up to six slots, two a day at most, each with its own temperature;
room temperature, refreshed every hour and on request;
an alert if the stove lights without you, caught at the hourly reading.

With Flam+:

5-minute monitoring of the stove, with temperature charts and statistics;
Flam Pilot: time slots with a target temperature (20°C from 7am to 9am on weekdays, 21°C in the evening), as many as you want, and a background temperature or switch-off outside them;
with Eco+, early ignition: Flam Pilot works out the ignition time from the outdoor temperature and your home's inertia, to hit your target at the start of the slot, and warns you if it expects to run late;
Eco+, which modulates the flame across the stove's five levels instead of cutting out and relighting at fixed thresholds;
alerts for a fault, a stove gone offline or a failed automatic ignition, and an unexpected ignition caught within minutes.

Flam+ can be tried for 10 days, no payment card required. Prices are on the pricing page.
