Hi

If I click on the link I'm informed the attachment doesn't exist any more. Watt is going on? A bit Phased perhaps? Maybe a Volt-face in offering the component? I think I should go now

Sorry, I was editing the post.
I have finished editing now so should be all good to go.

Hi

Got it thanks. I'll try and have a play with it tomorrow.

Great, thanks.
I would be interested in feedback, positive or negative as that is how we can improve components.

Hi

Dug out my old gadget (still works) so I'll try and test tomorrow.

Hi

When you hover over ReadPowerAlarmThreshold it informs that it will read the value in Watts. All good there.

However if you hover over SetPowerThresholdLevel it informs that it is going to request register vales blah, blah, and if you hover over PowerThresholdValue it informs it wants the Reg Address of the high value. Methinks your fingers got tired typing

I'll get back to you later once I've connected it up.

Hi Martin,

I've just installed Flowcode 10 and downloaded the component so I will test it over the next day or two and let you know. Thanks for all your efforts! Regards, Colin.

Hi

Thought I'd make things difficult

Rather than use the ESP32 as per the FAD project, I used a Pi Pico (which is new to me) and fc10..32. I connected the module and also a little OLED based on SSD1306.

Completely forgetting to use the FloatToString$ function I wondered why I wasn't getting expected values

Once the grey cells kicked in I'm pleased to say that everything appears to work fine.

I could read all values and I set a Threshold Value too. If the threshold was reached it would alert me to such and then reset Energy value.

With the threshold set at 1000, even with the Bay Lights on in the Evil Lab I was still a good way off, and in each iteration of my loop I'd see the Energy value increase. Switching on a power hungry machine triggered the alarm and subsequently reset the energy value.

Note that all the above was just to test functionality and I'm not suggesting resetting your Energy value should be linked to overshooting a threshold, well unless you actually want to...

Thanks for creating the component and other than the "tool tip" issue mentioned previously it seems to work well.

@Iain
Thanks for the great spot.
I have corrected that, and I need to correct some console messages as well.
I will post a corrected version on Monday.
Also thanks for testing the component out.
I'm glad it's working well.

@Colin
You're welcome.
There will be some finishing touches required e.g. like the post above.
Hopefully, all functionality will be working as expected for you as well.

Hi Martin,

I've tested this new component today and it seems to be working fine. I am using a 300A/100mA current transformer with my power monitor so I have to multiply the amp, power and energy values by 3!!! There is just one thing, I notice that if there is no connection to the module, all values come back at maximum. Is there any way to report CRC and no reply errors as with the Modbus component to trap these? Otherwise, all good so far. Regards, Colin.
