Ecowitt HP2551
« on: February 13, 2020, 07:32:43 AM »
I'm looking to set up my first weather station and this being my first post I apologies in advance if I am asking dumb questions that have been answered before. Here goes...
I would like to have a console displaying current conditions and I would also like to be able to upload to Wunderground/WOW etc. I am thinking of getting the HP2551 console and a suite of separate sensors for outside temperature/humidity, indoor temperature/humidity, barometric pressure, wind speed/direction, rainfall, UV and light levels in W/m2 and at least one additional temperature sensor for greenhouse and other locations.

My research so far has led me here but before before I commit I have a couple of questions:
Does the HP2551c comes with an indoor temperature/humidity/baro sensor or do I need to order this separately?
Iím also not sure what extra functionality adding a GW1000 would add and whether the attached indoor sensors can be read by the console?
What frequency gives the best range that I can legally use in the UK.

So I think I need the following:
HP2551c console
WS68 anemometer
WH40 rain gauge
WH32 outdoor temp/hum sensor
WH31 temp/hum sensor (2off, or more depending if the console needs one)
GW1000 wifi gateway depending on extra functionality.

Am I on the right track?

Welcome!

I think you have summarised nicely
To answer your questions the HP2552 which does not seem to be a product bundle anymore on their website is what you are after does indeed come with the internal temp/hygro/pressure sensor in the box
I think the HP2552 has been superseded by the HP2553 which exactly the same but come with the ultrasonic anemometer instead of the traditional wind cup version

The GW1000 gives you the ability to look at your sensor data on a phone app via live data while you are on your home network. It also uploads data and can be leveraged by third party software if you want to do clever stuff with your weather data as many folks do and is particularly popular facilitating the ability to keep a copy of your precious weather data locally.

In the UK you can legally use 433Mhz or 868Mhz of the 3 possible options. The 433Mhz has the most distance in theory from a pure radio perspective but given the power outputs involved is not likely to make much difference. If you go with 868Mhz then you will have the option to buy additional kit from other European sellers such as Froggit who only use 868Mhz but which will be cross compatible.

The HP2551-C can not see the the GW1000's internal indoor temp/hum/barometer.
The HP2551-C requires the use of a special indoor sensor. It isn't listed on the website because this special sensor is included with a complete station kit. If you are putting a custom kit together then you'll need to contact Ecowitt so that it is included in your purchase.

Thanks for the replies.

So the GW1000 adds phone app capability and gives some future proofing if I get hooked and want to store my own data and display using other software. Sounds like a good idea given the relatively small extra cost.

Do you think the ultra sonic anemometer is worth the extra. Presumably no moving parts so longer lasting and less maintenance. Can you gets spare parts for the ordinary spinning cups sensor or is it just a case of replacing the whole unit if it goes belly up?

Iíve emailed Ecowitt asking for a price for the bundle including the a couple of extra WH31 sensors. Where does Ecowitt ship from? Are there likely to be extra customs charges involved?

Yes, spare parts are available.

Yes I think so. But I'll defer to Mandrake which is in the UK to confirm.

Iím in UK and just bought a Froggit WH3000 SE off their German website, which is cheap and also in EU so no import duty (yet!).

Good starter system as itís all in one (although not as adaptable as some others) but the display is nice and it has full app / WiFi connectivity. As well as feeding Ecowitt website I have it linked to my own home IoT set up: a Raspberry Pi with WeeWx software in it to record all the data, also feeding a internet-based data dashboard (Initial State) via MQTT and Node-Red flow. All works really well.

I looked at the ďall in oneĒ sensor array versions but decided on separate sensors so I can place them at optimum heights. For instance my anemometer will have to be quite high to avoid too much influence from nearby trees/bushes but that would be too high for the temperature and rainfall sensors.

Iíll have another look at the froggit website to see if I can put together the equivalent bundle to the Ecowitt versions. As you say, this will avoid any import duties so might be cheaper, and maybe quicker too. If you believe everything in the media China could be effectively shutdown for a while with the Corona Virus.

Iím not a complete Luddite when it comes to IT but the Raspberry Pi and other techie stuff is outside my comfort zone so Iíll probably just stick with the basic built in web capabilities for now.

Had another look at Froggit and although they list the console I want, HP1000SE(HP2551), the WiFi gateway DP1500(GW1000) and the temp/humidity sensor they donít list the separate wind and rain sensors only the ďall in oneĒ array. Unless anyone knows different.

Looks like Iíll have to go the Ecowitt route and risk the import duty.

Yes, for now Froggit is not offering an equivalent to the HP2552 that you seek.

So to answer the tricky customs/import question.
In my case the fee came to a little over £15 for a full system which was mostly the service charge.
This was because I asked Ecowitt to minimise the value of the goods they describe on the shipping docket. They do this by describing the goods as evaluation to decrease the real value you actually paid.
Of course this is ethically debateable and each has to decide on their own if they want to do this.

I think however if you want the latest kit then you will need to goto Ecowitt.

You can purchase the spares for the anemometer from Ecowitt. The Ultrasonic is so new its impossible to tell how robust it will be but it looks like it should last reasonably well.

I think I can probably live with "ethically debateable" if the alternative is paying even more money to our new chancellor and anyway, as it's my first weather station I will be 'evaluating' it  ;)

As the ultrasonic is new I'll wait untill its been out longer to see what the longevity is like.

I emailed support@ecowitt yesterday asking for a price for the kit described in my OP (~midday UK time) but no reply yet. Maybe still on CoVid-19 extended Chinese New Year hols?

They are back and working though I not sure what impact the Coronavirus outbreak is having on factory production.
Very often orders are manufactured just in time for individual orders so that does introduce delays and Ecowitt always bench test before they ship.
The office hours being in the East means that they are online early hours through to at the latest lunchtime for Europe/UK timezone. This means that you wont get any response from Lucy now until next week at the earliest.

Don't expect super fast order to shipping but you will get super support and interaction from them.
In my mind I am happy to wait a week or two for the given fact I know I am dealing with the original suppliers and they will do everything possible to make sure I am happy when I get it!

Ok, thanks for the update. I realise I will have to wait a while so I'll sit tight for now and provide an update when I know more.

Thanks to all who replied for your help.   [tup]
