While trying to determine which Shelly devices to purchase, I have experimented with the Shelly1, Shelly1 PM, and Shelly 2.5. I am not able to obtain power consumption as follows:
In order to integrate the Shelly devices with Indigo, for each Shelly device configuration, in the Internet & Security Settings / Advanced Settings / MQTT needs to be selected.
With MQTT selected, Cloud cannot be selected - it's one or the other
I installed the Shelly App on my phone; with MQTT enabled (and Cloud disabled),
Controlling On/Off is possible
This app shows real-time power consumption for devices connected for both the Shelly2.5 and Shelly1 PM, but not for the Shelly1 devices
The app has a message that Cloud must be enabled to collect consumption data
On my iPad, I installed the more recent Shelly app which has a 'Beta' label under the Shelly logo in the upper left
On this app, all the devices are off-line, and cannot be controlled
Experimenting, I enabled cloud for one of my devices, and with it enabled, it does appear on the Beta version of the app
Using the website, home.shelly.cloud, the result is the same as the beta app - all devices are off-line.
In short, with MQTT selected, neither version of the Shelly app has useful power consumption data for the three Shelly devices, Shelly1, Shell1 PM and Shelly2.5.
Is it possible to configure the devices to obtain power consumption data? - in Indigo, the home.shelly website, or on either of the Shelly Apps?
