I've been happily using the HiTec Astro Weather Deluxe for four years on a 64-bit windows PC. I've also found HiTec to be very supportive and helpful. I use the Weather Sensor as part of an automated observatory and since discovering N.I.N.A., I've been using it to provide a Safety Monitor Flag into the sequences. I also struggled with having 32 bit drivers (my focuser has the same problem).

The solution I found was to use a marvellous piece of software from Optec - the Optec ASCOM Server. The server can present 32-bit and 64-bit driver interfaces to your client software but in turn connect to your 32-bit device driver. I use it for both my focuser and weather sensor. One little niggle - not sure if Optec fixed it - Optec provide two servers "Server 1" and "Server 2", this allows you to connect to two instances of the same device type. For some reason Server 1 in my system only connects to the ASCOM Safety Monitor Simulator! However, it's no problem selecting Server 2 and that lets me connect to my HiTec Weather sensor driver.

Hope that helps - no need to return these marvellous little weather sensors - just use an ASCOM server then get your N.I.N.A. "Loop while safe" sequences running!

I have no connection with FLO, HiTec or Optec other than being very happy with the service and support as a customer.

It works very well and I'd be very happy with it if only 64bit drivers were available. I can only include it manually in my workflow because I use a 64bit implementation of NINA and this product only has 32bit drivers, Kind of defeats the object of the device at least in my use case. Take away the driver issue and it is really accurate and easy to use.

Whilst the unit and software itself are fine, the lack of 64 Bit software is a major letdown. I wanted the device to specifically use with NINA and now find that it is incompatable. As per the previous review this defecit should have been pointed out in the sales information at FLO or Hitec's own documentation. If id know that the software was 32 bit only, i wouldnt have purchased. Im now stuck using email notifications via pushover as a workround in the mean time.

32 bit drivers only .. almost unuseable for Nina and modern observatory software etc that benefit from 64bit drivers. Very very dissappointed to have bought the unit, gone to all the trouble of installing the unit to only find it works in 32 bit. I wasted some hours on this project. This is a major fail and really should have been highlighted on the product description.

Product arrived within 48hrs of ordering - the usual efficient service from FLO.
Setting up emial alerts was more complicated than expected but that was mainly due to security issues with Gmail programming, but with help from FLO this was all sorted within a couple of days.
The weather Deluxe works exactly as expected, email alerts for when the sky has cleared and also when clouds have arrived or rain has started.
My only niggle hence the 4 stars was the serial connection, which meant I needed a serial to USB adaptor for use with any modern PC.
All in all a great buy and a happy customer.
