US$130 (the full price of the thermostat)
TL;DR
What did Rex (@Rex482906) use Grok Bot for?
Before buying the connected thermostat their wife wanted, a homeowner had Grok Bot research the options, and it turned up a 100% rebate from their utility that made the thermostat free. The rebate covered the whole price, so the thermostat ended up free. They say they're getting to the point where they can't live without the bot.
What they did
Their wife wanted a new connected thermostat, so they asked Grok Bot to research it before buying. Along the way it found that their utility offered a 100% rebate on the thermostat.
How it went
The rebate covered the whole price, so the thermostat ended up free. They say they're getting to the point where they can't live without the bot.

Worth knowing
- Rebates depend on your utility and where you live, often cover only certain models and may need an application or proof of purchase. Read the rules on the utility's own page before you buy.
- Price check: Grok: free plan; Plus (The X Subscription): US$8/month, or US$6.67/month on a yearly plan (US$80/year) (checked Nov 2, 2026).
