Hi. I have installed heat pump in my basement. Producer is “neoheat”. Heat pump have “front panel” (for configuration and monitoring) based on WLT-043R-NP00 device (it’s on Windows CE). I have option to additionally connect to that panel WFi IOT device USR-W600 or USR-W610 (by RS232), and via this device my pump could connect to myheatpump.com site and:
send real time data / work of pump parameters,
be controlled remotely but only from that site.
USR-W610 wifi module have “MODBUS TCP ó MODBUS RTU” option, but if I understood manual properly, it can be used only in case that my pump panel supports MODBUS RTU too, so I think that is not an option for me.
I’m looking for other possibility of connecting my pump to OpenHab.
USR-W600 and W610 could run own TCP Server, but to be true, I have no idea how to use it (with which binding / protocol (and probably in next step there will be problem with knowing proper pump “registers”).
Theoretically maybe I could use myheatpump.com site API too, but I think there is unfortunately no such one.
Apparently the site www.myheatpump.com uses HTTP rather than HTTPS, which is generally a bad thing for security, but good news for you because you could use a network trace tool (e.g. Wireshark) to observe the traffic between your PC and that site.
