ThingShow - ThingSpeak viewer - Google Play

To visualize charts ThingShow uses two methods you can choose from - ThingSpeak chart web API or MPAndroidChart library. The first one is used by default. Unfortunately it does not support zooming and only one chart can be shown at once. MPAndroidChart library allows to build multiple charts on single screen and supports zooming.

The channel ID and the API key is needed to open private channel.

To visualize public ThingSpeak channel, ThingShow automatically embeds widgets from ThingSpeak website. It can be chart, gauge or any other type of widget including MATLAB Visualizations that is shown on a public page of the channel.

A virtual channel can be created to group different widgets from different channels on one screen. Just give it a name and choose widgets from channels that are already setup in ThingShow. It is also possible to change widgets order within a virtual channel. Local widgets such as Gauge, Lamp Indicator, Numeric Display, Compass, Map or Channel Status Updates can be created on virtual channel using public or private channel's data.

Unnecessary widgets can be hidden for any channel type.

Any chart can be opened on a separate screen in details. Its options can be changed and stored locally including charts that are opened from homescreen widgets. This will not affect data stored on ThingSpeak server.
Any widget can also be opened on a separate screen.

Homescreen widget is very useful part of ThingShow that helps to view channel fields data without launching an application. One homescreen widget can visualize up to 8 fields from different channels showing a gauge, lamp indicator, compass or numeric value. Each field can send notification when value threshold exceeded. To fit into homescreen widget space the field name can be changed locally.

By creating Local channel ThingShow can act as a http web server in the local network storing data on the current device. It is compatible to ThingSpeak REST API and can mirror data to ThingSpeak server as well. Import and export options are also available. This is useful when there is no internet available or it is unstable. Also data can be remotely accessed from outside network by using free or paid VPN services like "Tailscale". You can use 1 full-featured local channel for free for a week. This channel must then be deleted and re-created to continue free use. The paid feature has unlimited local channels and no time limits. It all depends on the performance of the device. Keep in mind that the device will drain battery faster due to frequent network use.
