Find Best Price at Amazon"I acquired this in order to count the number of winds of wire being installed on an electronic pickup. What is required is that for example you take a common vice grip, I preferred the smaller straight face type for this application, and adjust the tension on it gradually until a clamping brings the clamp in line with the circumference of the shaft; as in you need to do a light tap in order for it to go on. If you do only a partial stroke they all reset completely except for the one at the end of the chain which is the first number to the left. Other than the technical installation of getting the collar set tight which can't be done with just the screw it is a very solid performer."
"I was a bit confused by that and a little frustrated that in order to "reset" it I had to go through the entire number sequence again."
"This is small, well built, easy to mount, and can also be used as a handheld counter if needed."
"This is a surface mount counter, does not reset, works like it should, is reliable and affordable."
"The ratchet works great."

"When I saw this board for the price, I ordered one to test out with my Arduino Mega board and it took all of 10 minutes to get it hooked up and working like a champ."
"So nothing else mentions it absolutely positively, and I was a bit worried, because the RPi uses a +3V output, instead of the standard +5V. The pins are pretty much laid out like an electrical switch on the wall."

"Static awareness needed so discharge you hands on the grounded metal furnace when mounting the board."
"Testing the unit with a jumper cable was a little more complicated. I did not understand that you power up the unit and briefly touch the cable to the two appropriate connections to get it to enter into the testing sequence."
"More ICM282 furnace controller board positive attributes. 1) Arrived on time. 2) Clear Instructions printed inside the box. 3) Made in USA by a USA-based company. 4) US-based support, which I did not need."
"Installation said to disconnect all Thermostat wires for self test ."
"Control board was a great drop in replacement for my failed Bryant board."
"This board has a maximum fan run setting of up to 180 seconds."
"I've found other reviews on various forums online that tell similar stories of early failure and poor construction."

Designed to work with the wires you already have, Sensi thermostat does not require a common wire (c-wire) in many cases, so it is compatible with most heating and cooling systems* (U.S. and Canada only). Set your Sensi thermostat to automatically adjust your homes temperature for location-based temperature control with geofencing, or quickly create a 7-day schedule to reduce wasteful heating and cooling when no one is home. Integrates with Amazon Alexa for voice control and Wink smart home platforms, and works with Google Assistant and Google Home using the free Wink app.

Find Best Price at Amazon"In my research I learned that my primary complaint the Nest - that the temperature swing was too wide - was addressed by Sensi's "cycle rate" setting. Nest's no-button design is cool, but using a thermostat is not a lecture in UX minimalism, and black-and-chrome doesn't really disappear into the background of my home (white trim and all). Granted, we didn't also install a second Nest to have more temperature sensors, and we didn't buy their $200 talking smoke detectors which also report environmental statistics back to the thermostat. Most people won't care about this but being a network security engineer, I'm impressed that the thermostat has exactly 0 open TCP ports, outbound communication is with one IP, and total traffic is very modest."
"--. I had been wanting to get a WiFi Thermostat for a long time now, but I held off because I was worried that I would buy one that wouldn't be compatible with my home or that I wouldn't be able to figure out how to install it. You select the wires that your current thermostat has, and then the app tells you what to label them and where they will go in the new thermostat. I had never replaced a thermostat before, and it took me under 30 minutes (which includes unboxing, looking for screwdriver, looking for AC unit shut off switch, watching how-to videos included with the app, etc). The app is handy because it also tells you your local Hi and Low temps from the forecast as well as the humidity in your home, upcoming schedule, set temp, actual temp, and the background is either blue, red, or grey depending on if your system is on Cool, Heat, or off at the moment. The only thing this is missing is a few more advanced options for the app, such as specific alerts (like if the temperature is changed manually, I would like to be able to get an instant alert on my phone) and an air filter change reminder that can be set for a certain amount of time (like 1, 2, or 3 months)."

Find Best Price at Amazon"I like the version that illuminates the last selected time's LED, and the LED under the power on/off button, when the light (load) turns off. Some of the reviews here talk about the night light feature, so I assumed that would be the version I would receive when ordering from this seller, but that was not the case."
"It's pretty bright but perfect for that middle of the night pitstop without totally shocking your eyes and taking forever to get back to sleep."
"For whatever reason (possibly the clothes in the closet were too close to the switch) it would just keep the switch on longer than programed."
"You can click the individual presets to turn on the fan or you can click the big button at the bottom and it selects whatever preset was used last."
"This is so perfect for just leaving the fan on for a while."
"Used to control the bathroom fan to ensure the moist air continues to be removed for 30 minutes after the shower."
"I push the "ON" button when I get in the shower and push the "20 min" timer button when I get out, fully exhausting the moist air not just from the bathroom but also from the ductwork so that no condensate drips back into the fan."
"The main difference between this model and others I have, is this one leaves the little blue LED indicator lights on all the time. The light is actually just bright enough that we don't even turn on the light in our small powder room in the middle of the night."
