Thank you, Tracy. Good morning, and thanks to everyone for joining our call. The resilient hardware plus monitoring service model of Acorn's OmniMetrix subsidiary delivered year-over-year and sequential revenue growth in the third quarter.
Total revenue growth for Q3 grew 5% versus Q3 of 2021 even in the face of macro headwinds, including rising interest rates, persistent high fuel prices, inflation and economic uncertainty. As we note each quarter, GAAP requires us to defer our hardware sales over 3 years and amortize it monthly into revenue.
On a cash revenue basis, our growth was stronger at 5.6%, and we provide a reconciliation of GAAP to cash revenue in today's press release. For Q3, our hardware revenue growth was strong, rising 17.7% year-over-year. This reflects our solid base business coupled with recent large volume hardware orders from a real estate management company that is deploying smart building technology across a new portfolio of buildings under its management.
On prior calls, we've discussed the sunsetting of legacy 3G monitoring units, a process which has now concluded, but it did have a residual negative impact on Q3 monitoring revenue as a result of certain customers that chose not to purchase new hardware with renewed service contracts when their older units were decommissioned over the past year. With this cycle now complete, we expect accretive monitoring revenue growth moving forward.
On our last call, I said we anticipated a stronger second half and a return to an attractive, sustainable long-term path for growth. We started to see that in Q3 and expect positive trends to continue in Q4.
Our positive outlook is based on Q4-to-date sales orders, purchasing and forecast discussions with current customers and new business leads. We are also confident about our longer-term growth prospects, especially in underpenetrated commercial and industrial markets we currently serve and from expected build in demand starting next year driven by demand response programs as well as opportunities in new complementary applications.
With regard to commercial and industrial opportunities in Q3, a global business solutions provider with approximately 250 U.S. locations began having OmniMetrix monitors installed for its standby generator monitoring control needs. OmniMetrix is currently providing monitoring at 36 of their locations.
And as mentioned, we also saw significant demand for our standby generator solutions from a current customer that is a real estate management company deploying smart building technology over a portfolio of properties. Our remote A/C mitigation disconnect solution for gas pipelines, which we call the RAD, continues with customer trials, including a few new customer prospects. We are pleased with the progress of these trials and are confident in the process for more orders this quarter and into 2023.
I touched on demand response already, but to go a little deeper, this is a great opportunity for 2023 and beyond, where our monitoring control technology plays a key role in enabling standby generators to be automatically turned on to provide electric power grid relief during periods of peak demand. This helps the grid independent system operators, or ISOs, avoid rolling brownouts or blackouts.
These demand response programs compensate generator owners each year for enrolling in the program along with additional payments based on the amount of electricity they take off the grid during peak power demand. OmniMetrix earns fees for enabling and managing the generator endpoints for demand response customers.
We believe these programs offer the potential to substantially increase the value of our business by approximately doubling our profit per enrolled generator. Demand response programs are available across commercial, industrial and residential markets but are only available to the latest generator models that deliver enhanced energy efficiency.
We partnered with CPower Energy Management, the leading national energy solutions provider who develops demand response programs with ISOs. This partnership will enable OmniMetrix to offer demand response solutions to dealers in a growing number of areas across the U.S.
We signed our first deal with Texas-based Power Solutions in the third quarter. Through this partnership, Texas homeowners will be able to earn compensation for offering grid relief to the Electric Reliability Council of Texas or ERCOT, which manages electric power [indiscernible] about 90% of the state's electrical load.
Clearly, electric grid issues are already a significant concern in the United States. And the growth of electric vehicle market, increasing severe weather events and other factors will create further grid stress over the next decade. We believe this backdrop can create long-term demand for grid relief and demand response provided by standby generators. And we expect to begin to see the financial benefits of this program to Acorn in 2023.
As it relates to our operations, our team has done a very good job and continues to execute and deliver despite macro challenges in 2022, many of which are beyond our control. In 2021, we implemented advanced procurement of critical components to protect against supply chain challenges. We still carry higher-than-normal levels of component inventory, but as supply chain returns to normal, we will be selling through our safety stock and return to normal inventory levels.
In terms of inflation, last year, we implemented a 15% to 20% price increase on monitoring equipment. And we will continue to look at pricing adjustments if needed to sustain our business and maintain our margins.
On the monitoring side, we have made investments in our infrastructure, both to enhance our service levels as well as to optimize our costs. Obviously, inflation has an impact on our costs, including personnel, travel and transportation expenses, et cetera. But it can also be an effective marketing issue as our monitoring solutions can reduce personnel costs, travel time, emissions and overall environmental impact required to maintain industrial assets and critical systems.
Therefore, as our customers' cost increase, our value proposition improves as remote monitoring provides a significantly less expensive alternative to physical inspections. Overall, while our revenue growth has lagged the rates that we believe are possible over the long term, I'm pleased with our team's success in navigating a range of challenges so far in 2022 as well as the growing number of growth opportunities we are advancing across the business. Further, we continue to invest in our products and services as well as our IoT infrastructure to enhance our competitive position and provide additional growth.
Let me now hand the call over to Tracy Clifford, our CFO and COO of OmniMetrix, to review and provide insights on our performance and financial position before we open up for your questions. Tracy?
