My display flow for the wattmeter is based on the decimal spacing returned from the F command, F00125D2; would be 1.25 watts. And if the third place in the information string is 1 then meter scaling is set for 0 to 2 watts. I was able to do some pretty cool stuff.

I just need guidance on what people want for control of the meter.

I use the metering in the KPA1500. I kept monitoring and control simple, to what I need for remote operation. But the nice thing with Node Red is any avalable command or info returned can be displayed. It is just how crazy you want to go.

For the people new to Node Red, install it and load some flows to look at the different nodes ?nodes to see how we manipulate the data. Looking at examples helps to learn.

As always, ask questions here. Pretty much any equipment with serial, USB, or IP can be added.?

Having used a W2 until last week (but for about 10 years previous) I found that I needed to hit 'scan' more than once.

Changing scales requires you to do math on the reported values.

BTW, for Scan, I think it requires a special firmware from Elecraft, but you would need to confirm they actually made the firmware public.

Actually I don’t have any at the moment.

Yes, I’m getting my way around. Currently I’m adapting some of our flows to my set up and combining them. And just started reading about Node Red and APC UPS.

Hi Santiago,

Hope you are progressing with Node Red.

What wattmeter do you use now? Does it have connectivity either via serial or USB?

Hi all,

I have finished the display portion of the W2 wattmeter flow.

What control functionality would you like to see? Forward power meter in auto range or manually set? (I personally like auto range).

Sensor auto scan or manually selectable? Or a choice between the two?

What other controls?

Once I get some feedback I will be able to have a flow publicly available to test.
