Shelly plugin
dumb question I know … I havent added a shelly device to my system in a long time,
I have a number all working ok.
I want to add a new device, .. I have its “identity” .. but the plugin demands? a password (which im not using on the shelly)
… so i appear unable to add the new device …
what am I missing?
(its a shelly 1 Plus)

For Shelly Plus 1 you'll want to use the newer signalk-shelly2 plugin
i have a number of shelly Plus 1 devices (~2+yr old) connected via the original shelly plugin,
these are working fine, im just trying to add a further device.
the shelly 2 plugin indicates its supports Shelly Plus 1 Gen 2 devices.
however when i look at the shelly information for existing devices via shelly web UI, it lists mine as “shelly Plus 1” … no mention of “Gen 2”.
so my conclusion is that trying to use shelly2 plugin will not be a solution for me …
I use the Shelly2 plugin with the same. The difference is that the new plugin actually works at discovering the Shellies without rebooting
ok noted and thanks for guidance,
as Im only using shelly 1 plus devices, i will update to the newer plugin as it sounds like its easier to use.
separate question:
does the newer shelly2 plugin expose “current” (amps) when using a PM version of a shelly device?
(i suspect this might? be a limitation of the shelly API? i recall it sends “power” (watts) , but not current)
That's something for @Scott Bender. Only Shelly devices I have that measure current are the RGBW2s, and those are gen 1, so using the old plugin. They report power (in Watts) but not current (in Amps)
But isn’t that just math?
It is, and I think the Shellies simply do a "current x 12" calculation. I had mine accidentally set to 24V mode for a while, and they reported double power
i believe the shelly PM devices are for measuring AC power (not DC) … (at least all the versions i have used)
and hence the matter of “power factor” needs to be considered...
so when reporting “AC power” , it “should” report 2 types, namely True and Apparent.
I have not used shelly PM devices with scotts plugin - so dont have direct experience on this.
(im using Tasmota flasshed to the shelly EMs etc)
if the shelly API (& hence the plugin) reports apparent power (VA), then yes it could be computed from VA/V=I
When using the Tasmota firmware on the shelly EM devices, it reports current (A) directly. as well as BOTh True (W) & Apparent (VA) power … which was why i was curious … because clearly the shelly EM (maybe PM also?) hardware has the ability to measure/report current.. (which the tasmota firmware exposes) .. but for whatever reason? shelly stock firmware doesnt appear to report it.
