Hi,
This maybe a jump in the deep end, but I am looking for help on reverse engineering the R485 protocol on the Hayward Inverter 81504 heatpump.
It is also sold under the brand Powerline by Hayward, and also different power versions (81514, 81524, 81534, 81544) sharing the same electroncis.
I managed to tap into the RS485 bus with my saleae logic analyzer and the RS485 bus is running on 9600,8N1 and I got an arduino mega256 w RS485 hooked up, reading the bus reliably.
Next up is reverse engineering the protocol so that the arduino can relay info/control the heatpump's on/off, temp setting and eco-mode over mqtt.
Did anyone venture reverse engineering this version of the Hayward RS485 bus?
I checked out the hayward/goldline AquaLogic/ProLogic protocols here GitHub - swilson/aqualogic: A python library to interface with a Hayward/Goldline AquaLogic/ProLogic pool controller. but that is completely different.
Thanks
