Frequently asked questions
Is Elewatt still free to use?
Yes. The Free plan covers a full setup — one contract, five automation filters and one smart device — with no time limit and no card required. Paid plans only add capacity.
What counts as a device?
A device counts toward your plan only while price-based automation is switched on for it. Connecting devices is free and unlimited, across all integrations: Shelly, Daikin, Samsung SmartThings air conditioners and plugs, Home Assistant entities (including Tuya / Smart Life devices bridged through Home Assistant) and evcc price feeds. (eWeLink and Nibe myUplink: coming soon.)
What happens when I reach a plan limit?
Nothing is deleted and nothing disappears from your account. You can't add contracts or filters beyond the limit. Devices are different: you can connect as many as you like, and the limit only counts the devices with price-based automation switched on. When every slot is taken, switching automation on for another device asks which one to switch off, or you can upgrade. Manual control keeps working for every device.
I have more automated devices than my plan allows. Will they stop working?
That depends on when your account was created. Early accounts, created before we introduced plans, keep unlimited devices free for life, on every plan. On newer accounts, if your plan's limit drops below the number of automated devices (for example after a downgrade), the devices you switched automation on for most recently stay automated. The rest stay connected and manually controllable, but their automation is paused until you switch another device off or upgrade.
How does payment work? Can I cancel anytime?
Payments are handled by Stripe — credit or debit card, charged monthly (or yearly on the Home plan) with VAT applied automatically. You can cancel anytime; your plan stays active until the end of the paid period.
Can I change my Business plan size later?
Yes. You can add or remove extra devices and contracts at any time — changes are prorated on your next invoice.
