Tymate 6 Tire Pressure Monitoring System for RV Trailer - Solar TPMS with 6 DIY Tire Pressure Sensors, Real-time Displays 6 Tires' Pressure and Temperature and Alarm Function- High Accuracy

Très utile, fonctionne très bien sur ma roulotte de 15' sans l'amplificateur de signal. Le seul bémol que j'ai en fait, c'est qu'il ne s'éteint jamais et il n'y a pas moyen de l'éteindre. Lors de mes séjour en camping je le mettait à off en pesant sur le bouton +comme indiqué dans les instructions. Mais après un séjour de quelques jours à l'ombre le récepteur était à plat. Parcontre des qu'il est au soleil la charge ce fait bien! Il serait bien d'ajouter un bouton on/off sur l'appareil pour ne pas que la batterie se décharge même en entreposage.

Set up appeared ok, but tire pressure after many trips continues to vary and a tire symbol is always appears after many resets. I don’t rest as easy as i had hoped.

Upfront, I’ve been only about two months into a year long journey with my family in a class C RV, traveling from Alaska down to the lower 48 states (5000+ miles so far), so this is the range I have worked with this system… and bottom line upfront, this system is untrustworthy junk!All six of my tires were brand new and I didn’t spare expense. Tires are critically important to the safety of operation and protection of family while driving, which is why I purchased a TPMS.The Tymate TPMS from the get-go was telling me that is was going to have issues when I had to replace most of the batteries.Set up and calibration was easy and I took to the nuances of the alarm going off for one or two random tires (always rotated) every time I started to drive even though I know the tires being reported were not flat or low pressure.Then the TPMS alarms kept going off when driving down the road randomly and kept going off… even though nothing was wrong with the tire(s).The alarms keep going off randomly, even for the tires closest to the monitor! I replaced the batteries, ensured the sensors were clean, recalibrated everything enough times that I could teach an instructional video and still the alarms keep going off well after I have been on the road. I even changed the alarm parameters to significant tolerance ranges and still the alarms go off.The tipping point of my patience and determination that this is untrustworthy JUNK came when the alarms when the alarms went off on a flat, evenly paved road, and the button used to silence the alarms permanently depressed in (from overuse) and wouldn’t shut off. 4+ hours later the alarm was still going off (couldn’t be silenced) alerting me that my tire pressure was out of tolerance. Battery has finally died along with my trust in the Tymate TPMS system.Yes, I have read the manual and completely understand if sensors are out of range… this is not the case. This device is just plain junk that is untrustworthy which is a serious problem when the safety of your family and other drivers are involved.

Pros: 1. Main unit/repeater and the sensors seem well built and I didn't have a problem installing those components. I have a 23 foot trailer and the main unit is at least 16 feet away from the sensors and the connection with the repeater works great. 2. The unit seems to work accurately but you need to be moving to get updated readings but there are many caveats and frustrations( discussed later). 3. The solar charger and manual plug in for the master unit works great and really nice. 4. The semi-sticky dash pad is nice and a must to keep this thing in line of site 5. The main unit LCD screen has plenty of size and could be far far easier to useCons: (I really need this thing but frequently tempted to throw it out the window at times) 1. You better keep the manual close by at all times because the interface and operations are NOT intuitive at all. You need to sit in detail with the manual and set up your thresholds for alarms on temp, pressure and adjusting scales of measurements aka (Farenheit vs Celcius and PSI vs Bar). 2. Once set it seems to work but it also chirps and beeps at times that i don't understand making it very annoying sometimes to know if something is truly wrong or its just beeping for a temporary condition... So i tend to just cancel the alerts and just keep it in line of site and check it from time to time. 3. You don't get real pressure readouts until you're tires are moving by design(Which the seller even emailed me about so you don't think its not working once installed).... And if you do get a readout while idle or just starting it up, it may be the last one the unit remembered and not a current reading which is another confusing point (Its not clear sometimes if it is showing a previous reading vs a current reading) I think it has to do with the sensor design and maximizing battery life... I think it uses tire rotation to actually engage the battery for operations and when the tires are stopped the sensors are unpowered halting the needless continuous transmission to the main unit. 4. Because you must be moving to get a reading you cannot take a pressure reading before you pullout on a trip unless you uninstall and reinstall the sensors which is a bit of a pain (keep your little tools close by as well as its not just twisting them off it has a lock nut). Otherwise you would have to drive get a reading, and if its low pull over and then put air in the tires on the road (Aka not desirable)... Would be VERY nice if you could tap the once sensor while stationary just to get a current pressure reading to the main unit. 5. It comes with dust caps for the sensors but there is absolutely squat about them in the manual as to when/if we should use them and the proper way to put them on... the install instructions says zilch about them. 6. If you are not using all the sensors like i am(single axle) its even more confusing... as there doesn't seem to be a way to inform the unit you are only using 2 of the 4 sensors So this makes the already cumbersome interface difficult to read and perhaps that is why it chirps sometimes because it chirps out of the blue when in "alert" mode... 7. I've accidentally long hit a button and it went into a "weird mode that had unreadable characters on it" and i finally got back after hitting another button a long time and playing with it.** The functionality of this even if partial and frustrating is worth it to me still... if i'm driving long distance and i occasionally see the PSI fluctuate a couple pounds due to getting warmer or colder i know its working and doing its them and i know what the temp readings are which is the basic safety features i'm really after... I think the UI could be 50 times easier than it is. I would be ok with the 1x tedious setup but the status display needs entirely redone along with how and what the unit alerts about is not intuitive...How about something VERY simple like flashing simple messages from a small library of phrases every few seconds like this1. Last read 3 seconds ago2. PSI: FR 65, FL 64, RR NA, RL NA3. Temp(F): FR 80, FL 82, RR NA, RL NA4. Alert PSI: FR 595. Alert Temp(F): RR 1806. Monitoring Paused/Disabled* And that's it... super simple

This has been a good purchase. Overall the TPMS works, gives us accurate readings, easy to set up.I cannot read the display in daylight as there is no backlighting at night and the display is very dark. This can be mitigated by setting up the low/high-pressure alarms and just ignoring the system unless something goes wrong and it alarms. Our car and trailer tires have a pressure increase of about 4 psi at highway speed so do not set the alarm at your cold inflation pressure. I have the low-pressure alarm set about 4 psi below cold pressure levels to alarm for a slow leak.If you follow the set-upprocedure it connects automatically, and even gave me accurate pressure readings before I started to roll.The new version comes with rubber boots that protect your rims from the sensor bouncing around which older posts note as a concern.
