Hello peoples I have ran into a bit of an issue with my pulse. As of just recently it has started reading higher temps then it should have been so I have been in contact with @okPeet (Who has been extremely helpful and believes he can solve the issue and I 100% have faith in that) to try and resolve the issue. We had discussed the possibility of heat build up from the vents being blocked so with that in mind I started experimenting with the pulse to see if I could remedy the issue. In the process I stumbled on what I think is the cause of my pulses issue ( I would like to say just cause I am having this problem doesn't mean everyone is)
"Hey Peter hope your weekend is going well. So I have good news / Bad news. I am pretty sure I know whats going on with the my pulse. (That's the good news) Here's the bad news I believe the mother board is heating up as well as the vents to vent the heat from building up aren't enough to do compensate for the added heat. So as the temps in the surrounding environment go up my pulse becomes more and more out on it's measurements. I tried taking the back off the pulse letting it sit then turned it on and checked what it read. It was spot on in agreement with the other hydrometer in my grow room. I also took lazer thermometer readings of the pulses mother board just before I turned it on and after a few mins of running. The longer the pulse ran the more it was off reading the temps as higher but the mother boards surface temps were the same as what the pulse read. I have pictures to show what I mean. I tried to match the pics so you can see three per testing. So the big issue is that when I had the pulse hung where I needed it the environment would be at around 76 to 77F with 55% humidity sometimes but the pulse would read as high as 84F with 40-45% humidity. Like I was saying the more direct heat on the pulse it compounds the problem. If you need any more pics let me know or want me to try anything. I will say just because I'm having this problem doesn't mean everyone is."
So this is what I sent him and he responded with I will get right on it and that he has a idea what might be causing it. That kind of service that quick is extremely nice and as I mentioned I have 100% faith the issue will be resolved. I will include the pics of the readings I took. I will update as soon as the issue is resolved.

Looking gooooooood!
Hi @okPeet
I have just read this thread start to finish..... very interesting thread and a very interesting product.
For some time now I have been monitoring my controlled grow room, using a system with up to 9 sensors measuring Temp & Rh (producing 1min interval charting), some home built switching controllers adjust Temp & Rh automatically via humidifier, de-humidifier and a evolution fan controller, (example 10 hour chart below)...... but up to now, without calculating or adjusting for the effect of VPD.

VPD.... True to say I knew a little about it, but not nearly enough, and it has slipped of my radar (until now).... You have definitely got my attention.
This seems the next logical step to me, being able to fine tune the grow room after calculating the effect of VPD.... So, I am Very Interested !
I have been looking on the Website to order, and have a couple of questions:-
Can additional sensors/setups be pre-ordered with the unit?
Can I pre-order for a UK shipment ?
What would be the expected UK shipment date?
Do we have a Coupon Code for AN members ?
I wish to purchase a full system, I am also happy to complete a documented trial with it, and post a full journal, with detail - as per some of previous grows (please take a look at some of my journals)
Thanks.

Garden is growing well. I've managed to fiind a way to control the humidity better. Hoping the damage isn't already done. My ph started to dip but I caught it early so I'm hoping I can fix fairly easy. If you look to the right in my pics you can see the pulse in it's new home. Girls in the back are about 5 foot tall.
