Solidremote Intelligent Wireless Relay Switch Receiver 2-Ch with 2 RF Remote Control, with Extended Range & Secure AES Encryption (KIT-2)

Adding this relay was the final part of installing an electric door bolt and accessories on a sliding glass door. Everything about this project was a hassle. The door bolt came with a relay that didn't fit, and it required fifteen wires to mess with instead of two. The design of the bolt didn't accommodate more than a limited number of installation options. And the component I used for a keypad equivalent was fussy, to say the least. Thin breakable wires everywhere. Battery-backup. Etc.And then the Solidremote arrived, delivered by Amazon on a Sunday morning. The Solidremote box gives you a sense of what you're in for. One side has a product diagram while the other includes a description, count, and illustrations of what's enclosed. The most unexpected touch: Pulling out the final tab, for opening the box, reveals a "thank you".The items in the box are nicely wrapped: the relay in a clear mini bubble-wrap sleeve, and each remote in its own little box (the second one noting that it's a limited-time complimentary item). The palm-sized instruction manual is about thirty pages of nicely formatted content in a readable font.I removed the relay from its protective wrap to find a solidly built device — not at all what I had expected for its conservative price. As previously noted, there was an extra remote as part of a promotion for the latest version of the relay. The aforementioned manual had much more information than what I needed for my application, covering a wide range of configurations, yet I could easily find what I required clearly stated with well-written text and a couple easy-to-read diagrams.The programming is extremely straightforward. Unlike my keypad, I didn't need a course in Morse Code to translate beeps. Instead, there was a nice readout declaring the current mode. Since my application wasn't fancy, and the relay's defaults were exactly what I needed, all I had to do (after wiring) was pair each remote to the receiver/relay. That couldn't have been simpler because the very first option, after pressing the programming button, is pairing. Quite literally, I held the button until I saw the number 1 (for relay #1), then pressed the desired button on the remote. It beeped and I was done. I pressed the remote button another time and the relay triggered exactly as intended.As noted in the review title, I felt incomplete. Where was trying something else because my initial attempts failed? Where was grabbing the manual to reread the instructions I thought would work? Where was the struggle? This is a horrible outcome. Due to the effort that preceded this, I wasn't inclined to pursue another project of this nature. It was going be manual locks for me. But now I have ended on such a positive note, that I already started thinking of other locations in need of an electronic lock. That's not how it was suppose to be.Other things I like about the Solidremote: To cheat, I'll repeat how solid it feels. I like that the wiring block is on the surface. Sometimes they're embedded in the case with holes provided for screwdrivers to reach. But then you can't see the screws, and if you loosen one too much, you have to open the case to fish it out. The clamps on the block are well made. Others are often not well-suited for a range of wire gauges, and they're like guillotines for thin wires. The voltage range is generous. The programming button, readout, and wiring block are easily accessible after the relay is mounted. Despite that, there's even an option for programming remotely in case the relay is inconvenient to reach after installation. What a great convenience. I like that there was no scrimping on the lights. There's one for power and each relay. I like that the beeps can be disabled. Best of all, I like that when I disconnect or lose power, the relay doesn't lose its programming. My other units require battery backup. Oh yeah, and there's also the reason I bought this relay: the ultra-secure encoding between it and its remotes. I have no doubt that if my use was more extensive, I'd find even more to like.In short, this is a great product that is thoughtfully designed, nicely executed, and sold at an extremely fair price.

I have the older 202U and this newer 402U solidremote kits, they are both great and i thought I would compare them in this review. As far as range is concerned in the open the older 202U is giving me about 100yds reliably activation and 140yds intermittent activation when I wave the transmitter around. This is a lot farther than any garage door opener or car key fob I have used before.The newer 402U is giving me 300yds reliable activation and out to 375yds intermittent activation when I wave the transmitter around. The receiver on the 402U is very sensitive to be able to pick up these small signals when so far away. Both devices use the same TX134 transmitters but they have to be in a different mode for each receiver. When you push a button and the indicator light on the transmitter comes on solid it is in 202U mode. When the indicator flashes it is in 402U mode. To place it in 402U mode you have to hold down the C button when inserting the battery in the transmitter. If you are in the wrong mode you will not be able to pair or control your module.Things I like better about the 202U, It's box is better, more weather proof and protects all connections and components better. The 202U has screw terminals for normally open and normally closed relay positions. The 402U only has normally open screw terminally but don't let that hold you up to much, if you really need the normally closed relay terminals they can be soldered to on the bottom of the board. The 202U has screw terminals for the limit switches where as the 402U has pins on the board for connecting the limit switches. The 202U uses a little less static power at 150mW vs the 402U at 250mW. The V5 version of 202U seems to have timing options that can be programed for how long a relay is switched, I have yet to find these options on the 402U.Things I like better about the 402U, the improved range is a huge. They both have antenna pins for adding external antennas but the 402U also has a proper micro coax connector which is nice. The 402U uses 128 bit AES encryption on the transmit signal making it practically impossible for something or someone to trigger your relay other than the transmitter you program, The rolling codes of the 202U are good and fairly secure but this is much more secure. The 402U has 2 additional switched signals (not attached to relays) for being able to control 4 devices. The 2 additional signals are active low meaning when activated a transistor switches the pin to ground, the manual says it can sink up to 300mA per pin. The 402U has a buzzer that can be used as an audible cue of when something is switched. The 402u can be programed for new transmitters without needing to take the case apart. The manual states that there is an option for an extended range remote TrioAES 433-X transmitter which makes the receiver 4dBm more sensitive, I would be curious to see what range improvements this provides once they are available.All in all, an Solidremote makes some very high quality products that perform amazingly well for a rock bottom price. Thanks

I was very pleasantly surprised with the design and features on this. I love the simple and smart programming interface of just a few DIP switches, a single button and 7 segment digit. Programming the remotes is a breeze; and the feature to switch the remote modes to the tri-band mode is very clever. The relay switching modes are adjustable to pulse, hold etc which is nice and the additional virtual relay channels are a nice touch. I'm just using this to replace the failing receiver in my garage door opener but I'll need to think up something fun to do with those. The range on the remotes is excellent, we can open the garage easily from ~60' away and any further would really just be a liability for us with accidentally triggering it when we can't even see it. I'm now thinking about anything else I might want on a remote so I can get more of these...

I purchased two 402U units for dual garage doors, one unit has been working fine, the other keeps forgetting the remote to my despair.Update:The units are fine ... but you must have a very stable power supply without any interference what so ever. Your DC bus needs to be clean of voltage fluctuations or noise, otherwise this causes the receiver to delete the remote (Clear the remote code) I have upgraded my power supplies x 2 (more expense), but have 100% response and no stray operation of my garage doors, which was what i was trying to achieve by buying these.
