WirelessPalaControl

This project uses "Palazzetti library" and a D1 Mini to control Fumis based stove.
It allows to power On/Off, change the setPoint, change fans speed, get status/alarms/temperatures of the stove.

Native HTTP requests are available which make is fully compatible with all existing Palazzetti/Fumis home automation plugins/apps.

Additionally, this project add MQTT protocol to monitor/control your stove in a much more efficient way.

Stove Compatibility

Fumis Controller is used by many manufacturer for their stoves. Here is a non-exhaustive list:

Palazzetti / Jotul / TurboFonte / Godin / Fonte Flamme / Invicta / Casatelli / Alpis / Faizen / HETA / ...

If you have this control panel and/or controller in your stove, it's compatible.

MQTT Integration (MQTT broker required)

Build your adapter

You can find details to build it here : BUILD

Connect

⚠️ You need to use a crossed RJ11 phone cable like this: ⚠️

Most of stove have an RJ11/RJ12 connector for PalaControl connection.
If you don't have it, you need to cable it using a splitter to connect screen and PalaControl at the same time :

Splitter and additional cable can be found on Aliexpress (search for "6p6c splitter" and "rj12 cable").
The splitter should correspond to this small schematic :

First Boot

During First Boot, the ESP boot in Access Point Mode

• Network SSID : WirelessPalaControlXXXX
• Password : PasswordPalaControl
• ESP URL : 👉 http://wpalacontrol.local 👈

Connect to this network and then configure it.

Configuration pages

Status

It returns you useful informations about the module and the stove.
The stove SN appears then 1 minute later, refreshed stove information appears (default upload period)

Config

System:

• Reboot: restart the module
• Reboot in Rescue Mode: restart the module with default configuration

WiFi:

• ssid & password: IDs of your Wifi Network
• hostname: name of ESP on the network
• IP,GW,NetMask,DNS1&2: Fixed IP configuration

PalaControl - Home Automation:

• Type: enable/disable MQTT communication
• Upload Period: delay between refresh of stove information (in seconds)
• Hostname,Port,Username,Password: MQTT server infos (username and password are - optional)
• Base Topic: prefix used for WPalaControl topic structure
• MQTT Type: defines MQTT topics and data structure:
  • Generic: publish raw values under the base topic (e.g. "{baseTopic}/T1" = "20.00")
  • Generic JSON: publish values JSON to "category" topic under base topic (e.g. "{baseTopic}/TMPS" = "{"INFO":{"CMD":"GET TMPS","RSP":"OK......")
  • Generic Categorized: publish raw values to "category" topic under base topic (e.g. "{baseTopic}/TMPS/T1" = "20.00")

Firmware

It allows you to flash a new firmware version using WirelessPalaControl.*.bin file:

Use it

HTTP

Natively, HTTP GET request can be sent directly to the module.
Syntax: http://wpalacontrol.local/cgi-bin/sendmsg.lua?cmd={command}

MQTT

Commands can be sent via MQTT to %BaseTopic%/cmd topic once MQTT is configured.
Execution result is:

• published following the configured MQTT Type
• published on %BaseTopic%/result in JSON format

Module connection status is published to %BaseTopic%/connected:

• 0: not connected
• 1: Module connected but no communication with the stove
• 2: Module and stove connected
