I have a corded electric string trimmer (“weedwacker”) which works decently – but being corded is a bit of a nuisance, so
I’ve been looking around for a cordless string trimmer (battery operated), as I’d rather not have to mess around with gas and all that. Here is what I came up with…
I’m very tempted to give one a try, but I have some larger weeds (say a half inch in diameter – like berry bushes) and I’m not sure if an electronic one will hack it…
Holding off for now, but just in case this is useful to anyone else, here is what I came up with.

In June of 2011, nearly two years ago, I wrote an article summarizing the state of IP (web-based) enabled thermostats. I revised this article in April of 2012, over a year ago. Now, it seems appropriate, to create a new post reflecting the state of IP enabled thermostats in 2013.
This article will include all information still relevant from the older article along with new information regarding developments from 2012 until now.
I welcome comments regarding this post including:
Any IP based thermostats I may have missed.
Your experiences with various IP based thermostats.
Without further ado…
Offers 24% cost savings on heating and 21% on cooling as compared to leaving thermostat fixed on 72 degrees.
 I was unable to find an RSS feed using Feedly to keep up with ecobee’s blog…That is a big no no!
Offers solutions for home and business.
Website is very nice, apps, etc. appear well-finished – but no noticeable distinguishable features at consumer level, though business units offer administrative flexibility beyond that found in home units.
Prices appear to start around $200 and go up.
Conclusion: Might be worth considering for larger building where administration controls are needed, otherwise, seems neck-and-neck with competition.
Images of ecobee’s thermostat and remote management.
Two different models are available direct from Radio Thermostat – the CT80 ($250) and the CT30 ($140).
Requires either a “C” or “Common” wire or an external power adapter.
3M used to rebrand/resell these under the Filtrete brand via Home Depot, but appears to have stopped doing so.
They also lack an RSS feed (or even a real blog), the website design is outmoded, and the devices are not as slick as competitor options. That said, they do have
online and public forums.
Radio Thermostat’s WiFi thermostat.
blog with RSS feed. One of the oldest IP thermostat manufacturers.
Pricing is not available on the website.
Used to have residential solutions, but there is no mention of them on the site anymore.
Site is pretty horrific.
Installs in 30 minutes.
No recurring costs.
Has an iPhone client.
Looks to have significant customizability but at cost of user friendliness, a geek’s friend, but perhaps not for the average consumer.
Pricing starts at $220.
Bay Controls’ Scary Geeky Thermostat
Receives disappointing site award alongside Bay Controls.
Offers web-based and PC based management software which looks nice and feature-filled.
The web management console is a server built into the device, no cloud services.
Pricing starts around $450.
Offers special pricing for non-profits.
Company website was slow, consumer facing site appears to be down.
Most recent press release is from 2011.
Wouldn’t recommend due to lack of activity on site, though devices look fine.
Appears to be rebranded via American Standard and Trane.
Offers the advantage of also supporting cameras, lighting, locks, and sensors.
Monthly fee of $9.
Utilizes Z-Wave technology, not WiFi per say.
Pricing starts at $150 for just the thermostat, but you’ll also need a bridge. A bundle is available for around $230.
Nexia’s Thermostat, Bridge, and Power Bundle
Created by former Apple folks, has gotten a lot of the recent press and consumer love.
Website and device appear beautiful.
Has partnered with energy utilities to offer the device for free if you sign up for select providers (only available in some states).
blog, including RSS feed. Devices are available from
Amazon as well as Lowes and Home Depot. Price is $250.
This system does not require a C wire.
The beautiful Nest thermostat.
Seems like Enphase is moving away from focusing on intelligent thermostats and focusing more on solar panels?
Uses the ZigBee protocol and thus requires a bridge device.
Website is slick and has a
blog with RSS. Only sells via distributors, no pricing easily available.
Offers both residential and commercial solutions.
Surveyor product which allows for HVAC, lighting/electrical, and mechnical systems monitoring. Claims (for Surveyor) “Go Green for No Green” (no cash up front, no capital expense, cash flow positive from day one). Didn’t see details on this program.
blog, but no RSS. Appears to work only through utilities.
Appears to work through utilities.
Offers the ComfortLink and ComfortLink II – both of which are web enabled.
The Nexia branded home thermostat starts at $150.

Requires a “C” wire, but also supports a 24VAC transformer.
Nexia’s Thermostat, Bridge, and Power Bundle
Full color available from $250 from Home Depot, monochrome from $120 for button-based and $150 for touchscreen. Appears slightly better pricing is available via
Amazon. All of these units require a “C” wire. If you have an older home/business you may not have this wire run to your thermostat. There are instructions on how to check on the website. It is quite unfortunate, there WiFi-less models have batteries that allow them to operate without the “C” wire, but these apparently don’t.

The Monochrome Honeywell Touchscreen WiFi Thermostat
The Button-Based Monochrome Honeywell WiFi Thermostat.

blog with RSS.
Pricing around $150.
I’d be hesitant to utilize anything that runs over Z-Wave, ZigBee, or Insteon. I think WiFi is the wave of the future – but that might just be me. What do you think?
The Nest, LockState Connect, and Honeywell options look the most attractive to me. I just signed up with a new energy utility and they are sending me a free Nest…so that is what I’ll be using at home.

I’ve been looking into
IP-based thermostats, that is, thermostats which can be managed remotely via the web. I’ve collected a number of vendors below. The idea is coming into its own and a number of companies have picked up on it and it is a great idea – as it could significantly lower electrical costs for homes and businesses. Before I move on to the actual reviews here are a few questions I have I’d love to hear your thoughts on:
Do you know of any other companies that manufacture and/or sell IP enabled thermostats?
Do you know of any companies that offer discounts to non-profits?
Do you know of any companies which support LAN-based thermostat management but not internet-based? I’d like to add them to the list…as they can be managed remotely via programs such as
