CAN-Gateway software is intended for communication with devices from Hoval AG that are equipped with a "TopTronic® E" (*) controller. This software must be executed on compatible hardware based on an ESP32 microcontroller and then allows:1. Integrate the devices into the home automation system (e.g. Home Assistant, ioBroker, OpenHAB, Domoticz, Loxone etc.). Supported protocols / features:MQTT protocolREST APIModbus TCPHome Assistant MQTT auto discoveryKNX IP multicast/routing (no tunneling)2. Control the devices online from anywhere using the associated Android app / Windows x64 app and read out the current data(**). Features:Encrypted end-to-end connection via the Internet.No cloud / server in between: the app accesses your system directly. So very quickly.3. Log data and save it on an SD card, e.g. for system or error analysis. Features:Data storage can be set flexiblyVarious data formatsWith the CAN gateway you can monitor and control up to 40 parameters in your Hoval devices at the same time.For performance reasons, it is possible to use/activate only one communication protocol (MQTT, KNX IP, REST-API) or data storage on an SD card at the same time. Although parallel use is theoretically possible, it can lead to performance problems and is therefore not guaranteed.Operating manual: CAN-Gateway_operating_manual.pdfWiki: https://github.com/wladwnt/CAN-Gateway/wiki/English-WikiYoutube video: https://www.youtube.com/watch?v=7HJrZkuCv4k** When ordering, please select correctly for which hardware variant (selection area below the price) ****Known Issues: There is some indications that the WiFi connection with some WiFi routers works very poorly (WEB interface from CAN-Gateway very slow) when the WiFi router uses radio channel 6 or 7. Solution: set your WiFi router to use radio channel 1 (2.4 GHz band). **Scope of delivery:Binary .bin file for flashing an ESP32 microcontroller. Will be made available for download or by email. The file is linked to a WiFi MAC address of an ESP32 microcontroller that you specify (please send us the WiFi MAC address by email to info@myhome-control.de). Detailed information can be found in the operating instructions.Please read carefully: CAN-Gateway important notesThis software has not been developed or assesed by Hoval AG.(*) TopTronic® is the protected and registered trademark of Hoval AG(**) For access via the Internet, your in-house network must have a public IPv4 address (dynamic, static).
