It is difficult to say what kind of protocol ? is used in air conditioning units.
Driver only for RapidScada V6
DrvXYE.zip by link on google drive https://drive.google.com/drive/folders/1luwmeaxOHmPBdVA74NSjbAIqSgrBgHnC
the driver is paid. If you have questions about test keys, please contact us by email (specified in the description files)
Testing on hardware with a real protocol of air conditioners is required, only the gateway from Daikin was at hand.
https://codeberg.org/xye/xye That’s all I could find
it states “Tested with an old Midea CCM/01E and a Mundo Clima MUCSR-12-H8”
And also (e.g. FrigoLine, Mundo Clima, Daikin, …).Basically these are VRV systems. Perhaps Dantex
Unfortunately, there are no native air conditioners for testing. Only the AF-X converter to connect to Daichi.
Hi @manjey73 , hope you are fine.
I am interested in this driver of yours. I have had the chance to monitor GREE and LG HVAC units and always had to quote expensive Modbus converters and lost most of these. This was for the old company I used to work.
I have had many times, people ask me if I can monitor their split HVAC and most of them GREE and some MIDEA, but these are so basic that not even the converter they sell is compatible.
Questions:
1. Are the X and Y ports the same of the serial bus of the cabled remote controls?
2. Would I have to connect in series with the inside unit?
3. Or those X and Y ports are usually on the condenser of the units?
4. And, could I (Would you share) load these codes into an ESP32-WROOM-32 and have this information sent as MQTT to the Rapid SCADA? This question is because I have my Rapid SCADA at my office and my customers get to it by VPN. I have to install expensive equipment to arrive to customer sites, if I send over MQTT I can economise and reach many more single unit HVAC customers.Thank you.
XYE is a protocol that is supported by some models. According to the interface, it is compatible in RS485. But some air conditioners, Midea, Gree and others have a different protocol. Often, some models sell converters to Wi-Fi that connect to the indoor unit of the air conditioner – there is a different protocol and TTL signal level.
1. It is absolutely not a fact, there may be another protocol. To understand this, it is necessary to determine the signal levels and, if they are close to RS485, try to connect with a computer using a USB-RS485 converter and try to receive the exchange information in the port eavesdropping mode.
2. If the signal levels allow it
3. It was like that on Kentatsu, in the external unit
4. There is a different programming language. There is no such possibility at the moment. There is a link in the documentation to reverse the protocol, which you can use to adapt the code to ESP probably. I think there are enough examples of mqtt for ESP too.
