Arduino Cloud vs Helioscope

Arduino Cloud
Software
Cloud platform for Arduino IoT devices and applications
- From
- Free
- Rated
- -
The short version
- Each has a real cost: Arduino Cloud the free plan allows 2 connected devices, 5 variables each and one day of data retention; Helioscope licences are single user, so each designer needs their own
- They diverge on capability: Arduino Cloud covers Device Connectivity, Helioscope covers PV system design.
Where they differ
Only the attributes on which Arduino Cloud and Helioscope actually diverge.
| Attribute | Arduino Cloud | Helioscope |
|---|---|---|
| Platforms | Arduino devices, Cloud, Mobile app, Web dashboard | Web, Api |
| Founded | 2005 | 2012 |
Identical on both: starting price (Free), pricing model (subscription), free tier (Yes), user rating (Not yet rated), category (Unknown).

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Arduino Cloud
- The free plan allows 2 connected devices, 5 variables each and one day of data retention
- Free accounts are limited to 25 compilations a day and 10 trigger notifications a day
- The Maker plan at $72 a year lifts devices to 25 and retention to 3 months, still for a single user
- Team pricing jumps to $1,000 a year
- Two years of data retention and unlimited ingestion require Enterprise
Helioscope
- Licences are single user, so each designer needs their own
- Projects are capped at 10 a month on both Basic and Pro
- System size is capped by plan, at 1.25 MW DC on Basic and 5 MW on Pro, so a larger array forces an upgrade regardless of project count
- Trackers, LIDAR modelling and API access sit on the higher tiers
- Enterprise is priced per project with no published figure

Questions people ask
- Is Arduino Cloud or Helioscope better?
- Neither clearly leads. Arduino Cloud starts at Free and Helioscope at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Arduino Cloud or Helioscope?
- Arduino Cloud starts at Free and Helioscope at Free.
- Does Arduino Cloud or Helioscope run on more platforms?
- Arduino Cloud runs on Arduino devices, Cloud, Mobile app, Web dashboard. Helioscope runs on Web, Api.
- Can I use Arduino Cloud for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Arduino Cloud best used for?
- Arduino Cloud is most often used for connecting arduino boards to a cloud dashboard, over-the-air firmware updates to deployed devices, logging sensor data and charting it over time, triggering notifications from device thresholds. Of those, connecting arduino boards to a cloud dashboard and over-the-air firmware updates to deployed devices are not what Helioscope is typically brought in for.
- What can Arduino Cloud do that Helioscope cannot?
- Arduino Cloud covers Device Connectivity, Cloud Storage, Real-Time Sync, Security. Helioscope covers PV system design, 3D shade modeling, Performance simulation, Single-line diagrams.
