Ah gotcha, there is a sensor already added in my code for this.
It’s a binary sensor called Pump On.
Makes sense, thanks! I’ve replaced both the esp32 and modbus matching your components but unfortunately I’m still having an issue with the “running” state. When the pump is off, the RPM is still reporting what it was previously so “Pump running” always reports “Running”
At the start of this log, the pump is actually off. Then I turn the pump on updates the pump RPM correctly to 2900rpm. I then turn the pump off (which does actually turn off the pump), but the reported RPM doesn’t update:
I’m using your code directly except for ota/api/wifi sections. Any idea what could be wrong here?

Does this happen all of the time or just sometimes?
I’ve had that occur maybe once a week, I’m adding some error checking to help find out why this occurs.
It’s a permanent issue on my setup.
I’m testing a fix for which also has more diagnostics
If it’s stable for 24 hours I’ll share it and maybe that can help show what’s going on with your setup.

Looking to do something similar for my pool setup; Norsup Variable pool pump.
14hrs in, fail fail fail 
If you look at earlier posts in this thread, it seems that these Aquagem devices don’t strictly follow modbus protocol. Because of that, they don’t work well or at all with out-of-the-box modbus gateways.
Hi there,
Thank you very much for all this work ! I have installed it and made it work correctly.
I did have some issues with the wiring (my previous deleted post), 20 minutes after posting I realized that I had badly wired RO and DI the other way round which needed to be wired with RX and TX respectively. Once that was resolved, it worked perfectly.
ESP wroom32 from SP cow (spare esp in my drawer)
5V MAX485 / RS485 TTL from Dollatek
Aqualux → French isaver+ reseller
Thank you !
Can you please try to the update I pushed to Github? It treats the states a little different and accounts for errors etc.

Thanks so much, I’ve only tested a few on/off cycles but it seems to be working perfectly now!
Thanks last update works great
My version of how to externalize the esp32 outside the isaver was to replace the contact sec (2 cables) with a thickness equivalent wire but with 4 cables (4G1.5mm) to avoid adding a new hole to the isaver. I then used a larger external wire box to host the esp32 / 485 set up and gave it enough wire length to place it somewhere with better wireless coverage.
I was hoping to have it all inside the isaver but that meant adding a 5v transformer inside and I was a little skeptical with how hot that can get during summer.
Since this update, when turning off “Pool pump power” it does turn off the actual pump, however, the last RPM in used is kept as well as power consumption and water flow (see image attached).
The following changes fixed the issue for me
Enabling reading low RPM Values:
// Treat very low readings as "stopped"
if (raw < 50) {
raw = 0;
}
// Sanity filter: accept 0 (off) or plausible running range
if ((raw == 0) || (raw > 500 && raw < 4000)) {
if (raw != (uint16_t)id(pump_rpm_state).state) {
id(pump_rpm_state).publish_state(raw);
id(pump_rpm).publish_state(raw);
}
id(modbus_status).publish_state("Online");
} else {
// Still ignore obviously bad values if needed
}
set pump_rpm_state manually to 0 after turning off the pump power.
- platform: template
name: "Pool Pump Power"
id: pump_power
optimistic: true
turn_on_action:
- if:
condition:
lambda: |-
return id(modbus_enabled);
then:
- lambda: |-
id(pump_rpm).make_call().set_value(2100).perform();
else:
- logger.log: "Modbus disabled: skipping Power ON"
turn_off_action:
- if:
condition:
lambda: |-
return id(modbus_enabled);
then:
- lambda: |-
id(pump_rpm).make_call().set_value(0).perform();
id(pump_rpm_state).publish_state(0);
else:
- logger.log: "Modbus disabled: skipping Power OFF"
Technically the first change should have been enough but I think it does not read the 0 value once it’s off. Second change forces the value to change to 0 and makes the rest of the values update accordingly (power consumption and water flow)
Hope this helps
Regards
Great, do we insert these lines anywhere? Otherwise, can you paste the entire hall file? Thanks
