I have a Hayward Super Pump VS 700 that I'm having issues with. I have is setup via RS485 (19200 baud) and can send the speed commands and the pump responds. However the response from the pump isn't working. I've attached a replay. It looks like the response from the pump is trying to be process as a chlorinator and not a Hayward VS. I'm on commit d7b0993. Also, are we able to update VS pump speeds via MQTT? I looked and it doesn't seem to be listening to the config/pump topic. |

Actually I see chlorinator packets in there but there is no response from the Hayward pump. How old is your pump. We had another person that attempted to connect via RS485 only to find out that the old VS700s do not talk back. The speeds are set by turning on and off specific circuits that have speeds assigned to them. For instance, when you turn on solar you may want to ramp up the speed but if only the pool is running you then the speed is lower. The circuit with the highest speed always wins. |

I do have two separate RS485 ports since the pump and chlorinator run at different BAUD rates. I have the aquarite swg on port 1, and the hayward vs on port 2. For port 1 I get:
For port 2 I'm seeing. Seems odd that the protocol for the "in" is chlorinator. :

Pull njsPC and dashPanel. I added some code to route the messages properly. After you update can I get another replay capture? |

Any idea why my pump would max out at 85%. When I try to turn it on max speed and send 100%, it'll only run at 85% (2933 RPM). What's really strange is that if I set it at 86% it'll run at 86%, but anything over that it drops to 85%. Replay for completeness. Thanks. When using the on-pump controller prior to unhooking them for RS485 it would run at 100%. |

This has to be a setting on the pump. In looking at the messages Nixie is requesting 100% and the pump is returning 85%. There is a Max Allowed speed on the pump in the manual but I don't know how to change it. The good news is that I know the pump can run at 100% given replays from @nate-marshall. Here is a message sequence that should be occurring And here is what we are getting from your pump Can I get you to go through the manual for your pump and make sure you do not have a max speed set on it. Also, if there is a priming setting it may not allow the pump to run at full speed until the priming cycle has completed. |
