Sensit is not fit for purpose

Sensit is not fit for purpose, Duped into purchasing a product that simply doesn’t work.

Connection issues constantly and when it did connect (once) it read double the amount of liters physically held in the tank so was 100% incorrect. Smashing stuff.

Emailed customer support twice (no repl) and no phone number to get in touch either.. The reviews of the product and the company speak volumes.

Reputation is everything.

Horrendous company

Horrendous company, was booked for a call out/ service at over £400, when engineer came out he did t service it and just put a new belt on which I paid for on top, still charged the full amount. Needed new motor as other was corroded and had to pay over £2000 upfront. Charged for two engineers, only one came. Parts that was not needed was returned for refund straight away and too them two weeks to revive them from DPD they said 🤨. Over three weeks for a refund of just over £1000 parts and second labour. Constantly had to chase. Stay well clear- I will be now - shocking company

Replaced a previous version which was…

Replaced a previous version which was the simple wall plug in this failed when the fragile battery clip snapped when trying to change the battery. Upgraded to the sensit app version.

1. If your selling an app version then adress reliability issues

2. Took forever to set up having to input information over and over again

3. Took 3 days to get a reading and it was not due to the router

4. Keeps loosing connection - for no reason the transmitter is only 10m away

5. Does not store the recorded data - the graph is ok if you have run this about 6months but early you want to see it’s working.

Overall a poor attempt at something which should work without issue

Would not recommend, who wants an automatic system that you have to keep manually restoring

Currently this morning the monitor is red but is not telling me to do anything, please support , update and improve your product

They didn't reply deliberately and are trying every trick in the book to try and avoid doing the right thing. Hope the company folds ....... Sooner the better

Kingspan Sensit not fit for purpose

Bought a kingspan sensit at the beginning of August and have had constant problems with it. The usb stick only works for a few days at a time then the light turns red and won't work until you unplug it. Even when it's green, readings are up to 5 days late, I've not seen readings every 24hrs as promised. Sensit support phone line rarely answers a call and email support doesn't respond. Don't buy this product!

Sensit is not fit for purpose, every Wednesday it disconnects, light goes red and stays red.
Kingspan web says red light means no internet connection, not the case here as device shows connected on my router. Problem is must be at Kingspan end. This happens every Wednesday like clockwork. No one bothers to respond to contact
UPDATE
Customer services contacted me Thursday/Friday and started an investigation, system started up early hours Saturday morning and has been working fine ever since (4 days). Someone obviously found the problem and fixed it, hopefully

Don't pay outright for annual service contract

Had good service from the company for a few years but this year I renewed my service contract as a one off payment (in February over £300) - rather than pay a monthy subscription. In April when I had a problem the call out was another £300 and the engineer turned my solar system off as it was faulty and I couldn't afford the £1200 to fix it. I asked for a pro rata rebate on the annual service contract as it had only run for two month but no such luck so lesson learnt- always pay monthly subscription which can be cancelled NEVER a one off payment for the whole amount (my fault as I had the option) so just be aware as also repairs on solar are very expensive as labour is £322 per hour!

Update: did email them my contact details as they requested in their response but heard no more from them so assuming just a generic response to look proactive.

Having purchased a bio filter water treatment plant for my home and joining Kingspans 'Gold' service contract and being told everything is covered. It turns out it isn't! Funny how they seemed it necessary to send a second engineer for a single cracked pipe equivalent to water waste pipe and charge £372 🤔🙄 Seriously my plumber could fix it in 1 hour for less than £100. Service contract is an absolute con. The customer service isn't great either.

Purchased a dongle for my fuel tank but had constant issues. Trying to get tech service to help or call back is trying at best. They just seem to stall and claim no record of calls, who did you speak to etc.

Hiding behind technicalities of a warranty.

This is a follow up to my previous ‘Lack of urgency and understanding’ review.
I was hoping I would write something positive following my numerous communications with the Kingspan team, well I’m not.
To say I’m disappointed is a huge understatement, Kingspan haven’t taken any responsibility with faulty parts and amateurish commissioning of our pump chamber. The chamber was commissioned 3 months ago and isn’t covered by their warranty because it was delivered more than 12 months ago!
They gave me a call out time of 3 days and charged me £964 for it, I found Mawdleys Pump Services which are based in the south west of the UK, they turned up within 4 hours and got the pump working albeit one pump rather than the two and charged a little over £300. They also found the floats to be intermittently working and the pump capacitor and thermal overload switch had overheated, the pump wasn’t blocked.
The Kingspan warranty team concluded that because it wasn’t commissioned, operational and serviced within 12 months of delivery the works couldn’t be carried out under their warranty.
The cost of the visits and replacement parts has cost me just shy of £3,500.
I still haven’t got my money back from Kingspan some 10 days later, it’s due to me in another 7 days time.
Kingspan - don’t bother sending me a customary reply, you didn’t liaise with me thereafter, I had to chase you again.

Homophobic, vile language, disgusting!

Seem's the manager Rob Gadd of this company shares some interesting views about an LGBTQ+ charity helping children on social media and some pretty VULGAR, derrogative language thrown in. Reported to council and trading standards.

Watchman Sensit

Purchased a Watchman sensit USB receiver. The app is appalling and almost impossible to set up. I've tried on multiple devices and different networks and generally end up in a loop. After several hours I actually managed to get to the create account page and it then threw up an error with no explanation as to why. I've now given up and going to try and get a refund.

Terrible company

Please be very aware before using this company. I contacted Kingspan to service my solar thermal panels which worked well for 10 years and as soon as the engineer left, I discovered that the panels had stopped working. I wrote to Kingspan who then told me to contact the installers. In fact they were responsible for installing the panels but told me it was not their problem. The engineer who did the work clearly was not trained properly and his manager defended him by saying that everything he did was correct. They also did not want to compensate me for the money I had paid for the service. Be very careful, this company should not be offering services as they are INCOMPETENT and if they cause a problem you are on your own.

Sensit USB device problems

This post is not intended as a complaint but is what happened to me trying to install the Sensit USB monitor and phone APP. I followed all the installations instructions which were very good until it came time to pair the USB device Wi fi to my network Wi fi. At this point the LEDs were flashing green as per the instructions but the minute it asked me to pair the devices the all the green Led's went out ato be replace by a solid red Led with a congratulatory message but the APP then was frozen and had to close all apps on the phone to regain control and then I noticed that my Watchman Sonic Advanced monitor was no longer working having been disconnected from the transmitter and not getting the normal signal so this required a new pairing set up to get it back up again and working once more. I tried all sorts of methods including several re installation of the app but to no avail and I even phoned customer services who asdvised to let it stand for 24 hours too see if it worked.
I subsequently foraged around the net for information and found a support document that said it would not work with mobile broadband routers. Now, I live in a very rural area, where there is no broadband service other than to use the 4G Mobile Phone internet connection with a 4G router system hence the problem. This information should appear clearly on the purchasing pages to avoid all this hassle. I have sent it back !!!
