Absolute LEGEND.

Thank you

Hi, I have just installed this variable speed drive and all is working well. Thank you for your work on this. I have seen that the unit displays the power consumption in watts, is it possible to send this information back to HA?

NightWatcher · May 2, 2025, 9:02am

No, this is not possible. I track the power consumption with an PZEM-004T.

Teflon77 · May 3, 2025, 3:10am

OK Thanks I will just put a power meter on the feed to my pool tech space.

I am a noob +++.
I am only starting with HA on a raspberry pi.
I want to be able to control this frequency inverter through HA, and also set some automations later on.
I want to connect the saver with a usb to rs485 connector. That worked. HA ‘sees’ it on usb0.
If I’m right , the code provided here is written for using an esp (so wirelessly?) instead of a usb-connection. Is there a way to get somewhere this code for a direct usb connection ?

For starters, this is my configuration (chatgpt helped)
modbus:

name: “isaver”
type: serial
method: rtu
port: /dev/ttyUSB0
baudrate: 9600
stopbits: 1
bytesize: 8
parity: N
delay: 2
timeout: 1

sensors:
- name: “Pump Power Consumption”
  slave: 1
  address: 0x1004
  input_type: holding
  unit_of_measurement: “W”
  data_type: uint16
  unique_id: “pump_power_consumption_sensor”
- name: “Pump Frequency”
  slave: 1
  address: 0x1001
  input_type: holding
  unit_of_measurement: “Hz”
  data_type: uint16
  unique_id: “pump_frequency_sensor”
switches:
- name: “Pump On/Off”
  slave: 1
  write_type: holding
  address: 0x1000
  command_on: 1
  command_off: 0
  unique_id: “switch.pump_on_off_2”

(But it’s not working yet)

if someone wan’t to retrofit the external control (modbus,digital,analog) for the newer iSaverX models, like:

you can find this and also a more advanced esphome (8266) configuration here:

I have Rapid X20 inverter. I’ve implemented the interface as described, but it doesn’t work as expected. The state of Modbus is “Online”, but the value of RPM is most of the time “0”, sometimes it shows different values like 512, 4096, 16384, 32768. I’ll be grateful for some advise how to improve it.
Here is my config:

Hello everyone! I have an InverMaster pump and an iWash valve. I was wondering if any of you had the modbus protocol for these products and/or if you were already been able to integrate them in to HA

Thank you for the help!

Anton2079 · January 6, 2026, 8:01am

Update: I since worked out it was a broken packet issue where it was fragmented sometimes, so I’ve added some error checking smarts to disregard those values. Works great now.

I have the same Madimack Pump, and tested your code however it seems a little unstable, not sure if you’re getting the same results?

I’m using an ESP32c3 with EVTSCAN TTL to RS485 Converter Module

milwhite · January 7, 2026, 10:56am

Great to hear! I personaly haven’t seen this happen on my pump controller, but would still be interested to see how you fixed it if you wouldn’t mind sharing the updated snippet. Cheers!

Anton2079 · January 8, 2026, 12:39am

G’day @milwhite

I’ve made a fair few changes as I’ve added extra functionality like Watt and Flow throughput as well.

To make it easy to see the changes I’ve forked your github and have a file diff for comparison.

FYI all this is for Madimack Inverter Plus

milwhite · January 8, 2026, 11:06am

Thanks for uploading that. Looks like you’ve added quite a bit of cool stuff!

jortan · January 9, 2026, 5:40am

Thanks to all contributors. I have the Madimack Inverter Plus pump controller. @Anton2079, I had the same modbus message instability and your updates fixed this. However with both versions I’m having a separate issue where ESPHome will successfully turn off the Madimack via Modbus, but 15-30 seconds later, the pump will start up again by itself. At that point the ESPHome switch remains “off” even though power has returned. When esphome switch is turned “on” again, current_rpm values start to update correctly.

I have power cycled the Madimack and confirmed that when I turn off using the Madimack control panel, the device stays off. There are no timers set.

In logs below I am turning off via ESPHome at 15:19:03, it turns back on around 15 seconds later.

I’m using Olimex ESP32-POE-ISO (not using PoE), and this for rs485:
https://www.ebay.com.au/itm/303970122565

Is it worth sourcing alternatives for these?

edit: Just realised I had a spare RS-485 module - tried this but it appears to not receive any modbus signals at all as the RPM was never updated. It does transmit modbus however, but I still had the issue of the pump turning back on.

I’m wondering if the dry contacts would be more reliable.

Good to hear some of the fixes assisted.

To clarify are you using a blend of both code or all of mine?

I asked because my code removed the read write limitation which was originally on because of the RS485 chip, didn’t exist on my RS485 which manages that for me.

Also did you have this power issue with the original code or only message fragmentation issue?

jortan · January 9, 2026, 2:36pm

Not a blend - I’ve tried both versions of the code now. I don’t know if it will help but I’ve just ordered the XIAO ESP32C3 and EVTSCAN RS485 chip.

I had the power issue with both versions of the code.

Anton2079 · January 11, 2026, 11:38pm

Hmm I’ll wait until you match the components first and then I can review the logs.

jortan · January 12, 2026, 12:39am

Oops, how embarassing. It turns out I had a test automation that was triggering the speed change buttons while the pump was off. This physically turns the device on (which is good and will make my automations have less steps). The thing that was throwing me is that while the ISaver/Madimack was physically turning on, the ESPHome switch entity was still off.

Can I suggest having the switch entity update in this scenario as an enhancement?

Anton2079 · January 12, 2026, 5:44am

Ah that will do it. Glad to hear that’s sorted.
To clarify you want the speed change buttons to be disabled when off?

I don’t mind it turning it on personally, kinda like how you press a number on the TV remote instead of going power on first.

jortan · January 12, 2026, 7:04am

I agree that turning the pump on when a speed is selected is a bonus. I was more asking that if the pump turns on, could that be reflected by turning on the switch.pool_pump_power entity? At the moment the switch and the actual power state of the device can be out-of-sync. To illustrate, here my pool pump is actually on (via using a preset speed button), but the pump appears to be off:

(Ideally the switch would update based on the actual status of the pump from modbus, because other things outside the ESPHome device could have turned on the pump. But if that’s not possible then using the speed controls while the pump switch is off should turn the switch on)
