This project is to modify Panasonic CZ-TAW1 Firmware to send data from heat pump to MQTT instead to Aquarea Cloud (there is some POC work proving there is a posiblity to send data concurently to Aquarea Cloud and MQTT host using only modified CZ-TAW1 ,but it's not yet implemented in this project )

- OpenWRT Image with preinstalled GoHeishaMon (and removed A2Wmain due to copyright issues)

CZ-TAW1 flash memory is divided for two parts called "sides". During Smart Cloud update A2Wmain software programing other side then actually it boots ,and change the side just before reboot. In this way, normally in CZ-TAW1 there are two versions of firmware: actual and previous.
Updating firmware with GoHeishaMon we use one side , and we can very easly change the side to Smsrt Cloud (A2Wmain software) by pressing all three buttons on CZ-TAW1 when GoHeishaMon works ( middle LED will change the color to RED and shortly after this it reboots to orginal SmartCloud.

Unfortunatly from Smart Cloud software changing the side without having acces to ssh console is possible only when updating other side was take place succesfully.

Summary:

It is possible to go back to orginal software (A2Wmain with SmartCluod) very quick , without preparing pendrive ,becouse this solution don't remove firmware with A2Wmain (is still on other "Side" in the flash).

Even the GoHeishaMon is on other side you can't just change the site in orginal software to GoHeishaMon without acces to console. You have to install GoHeishaMon again.

## Installation

For installing GoHeishaMon on CZ-TAW1 you need a clean USB drive FAT32 formatted (there is a problem with some pendrive vendors if it didin't work try another one, becouse of big drop of voltage on USB port please use USB flash memory stick.) https://github.com/lsochanowski/GoHeishaMon/releases/tag/1.0.159

- openwrt-ar71xx-generic-cus531-16M-rootfs-squashfs.bin
- openwrt-ar71xx-generic-cus531-16M-kernel.bin
- GoHeishaMonConfig.new ( It is config.example file edited according to your needs and changed it's name. Please pay attantion on file extantion ,since in Windows .txt is often added)

After inserting drive with this files in runing CZ-TAW1 you need to push 3 buttons at once for more tnah 10 seconds until middle LED start changing the colors: green-blue-red. You may also notice the LED blinking on your drive ( if drive have it).

Process of update starts ,and it will take app 3 min. In the meantime CZ-TAW1 reboots , and after a while you will notice middle LED lights white color . Wait with removing drive from module until the white LED turn off again ( that is a sign , that GoHeishaMon copied config file from drive and reboot CZ-TAW1. You need to remove the drive before the white LED turn on again , becouse the config file will be copied again and reboot if the drive with a config file will be still present.
