Bonjour , perso je met trois piles rechargeables dans la console et plus d'economie ,plutot que de changer les piles . Es que vous avez développé une nouvelle  console  pour remplacer la console vp2?
Installing rechargeable batteries is not a solution for me because, like regular batteries, they will eventually run out and need to be recharged in time before the voltage drops below the threshold.
The DC UPS I installed may not yet be tested over a long period, such as 3 years, but it has the potential to relieve VP2 users from remembering to change batteries.
We are talking about a problem with the SMART logger here.
In reality, the batteries are there to keep the console and clock running. If the console turns off, we may lose data. The data may be recorded with the wrong time.
WiFiLogger will set the clock, but it may be too late, and the data in the data logger might already be recorded with the wrong time.
The console was not designed for WiFiLogger or the original WL IP.
If we are already making modifications, perhaps it should be done from A to Z.

I am not developing a new console. The new console from Davis, the WLC (Weather Link Console 6313), is very good. It has a clear display, nice charts, and receives data well from the transmitters, etc.

The only problem is the lack of ability to export data to a table, as was always possible with the VP2 and WeatherLink PC software. But these needs are not necessary for the majority of users. I think the average user appreciates the WLC as it is. Paying for a subscription is not a big problem for citizens of the USA, Canada, the UK, and a few others, where the main market for Davis stations is.

Personally, I sometimes glance at my WLC and wonder if it is possible to do a JailBreak and Custom Firmware (CFW) to extract its data and even enable custom data exports.

For me, Barani is no indicator of accuracy in all conditions. What J. Barani is pushing as the successor to the Stevenson cage is not true, that it is the most accurate in all conditions, because it is not. I have it as a comparison and most of the time it coincides with the ventilated one.

The Apogee TS100 is more susceptible to humidity than the Davis FARS24H. This we know from tests in the country.
I’m honestly just going to stop replying to you @Meteorology fan, you repeat the same points over and over and over again and you just straight up ignore any input from others. Like I’ve explained a thousand times why response time isn’t the only explanation for the FARS overheating like 0.3-0.5C compared to the Barani and yet you repeat that same narrative over and over again, it’s like talking to a brick wall… You have made all your arguments very clear and I accept them, we just disagree on how significant they are. I just look at the stats and I see that the periodic error on the Barani has zero effect on the long term averages where I live, so for me, it’s not a dealbreaker by any means. For you, it is and that’s fine.
Have you considered scenarios where the actives may be overcooling? Nice to have more than 1 active by the way. Still considering getting an RM young.

Sure want want the theoretical “real” air  temperature, but all shields are going to give you a wrong picture at some point or other. So the question should be how good or bad the shield is, not if it overheats under certain circumstances. The Barani can overheat, but as far as passive shields go none of mine have performed better than the Barani.

Having more issues recently with my TS100 than the passives by the way. All the rain and humidity is really hurting it (that is the PT100s inside) combined with strong evaporation when the June sun comes out.
This is important, because on the active we will find out when the covers overheat without active ventilation. For me, it's a comparison and I know when what's happening. I will not give up the passive and leave the active alone because of the risk of failure of the fan, for example.

Apogee TS100 also in windy conditions can show a higher temperature than even Davis FARS24H. This may even be due to the response time. In windless conditions, the Apogee TS100 can be cooler than the Davis FARS by 0.1/0.2 degrees relative to the TS100, as colleagues have already verified. Then the passives are overheated by 1-1.5 degrees.

I am interested in the actual or close air temperature. And not the shield temperature, but the air temperature in equilibrium with the outside temperature. In my valley often flow problems and Barani extremely often overheats. In the Belgian and Dutch climates, there may be fewer such days, due to higher wind speeds.

The worst thing about the Barani Meteoshield Pro III is that it shines from the side and overestimates by up to 1-1.5 degrees when the wind blows weakly around 1 m/s. This is a serious flaw in this shield that J. Barani does not talk about. We checked and the WMO Screnn does not suffer from it. Apogee TS100 doesn't either, and the same for Davis FARS24H.
I constantly see comparisons between active and passive shields. Surely important, but shouldn’t the more interesting comparison be between passive shields? All passive shields overheat. My Baranis consistently do so below 0.5 m/s in high sun, but this is no surprise. The question is how it then compares with other passives, and the Barani does very well in that battle. At least in my location.
The lower temperature in the Barani is, beside maybe 0.1-0.2C, true and I’ve explained why about a thousand times now… And I’m not sure what’s not true about my statement? If you look at 1 month for example, if you have 28 days where the Barani is 0.2C cooler and then 2 days where it’s 0.5C warmer, the Barani will still have a lower mean max if you simply do the maths… I haven’t updated my sheet in a while but if I suddenly added 2 days where the Barani is 0.5C warmer, it won’t undo the 30+ days where the Barani averaged 0.28C cooler. For the effect you describe to have an actual impact on climate stats, this would need to occur over multiple days to even weeks and this is simply not going to happen in our climate, maybe slightly more where you live but still not significantly so.
Jasper3012 - this is not quite true. Two days earlier the Barani Gen III overheated again during the summer weather. SHT35 snapshot below, I confirmed it on PT1000 4-wire. Remember that in the case of Barani, the lower temperature is not always true. I think there will be more such periods with significant overheating this summer, and it will depend on wind speed and sunshine strength. At the time of yesterday's overheating, there were gusts of about 1 m/s, but what if there had been total calm, Gen III would have overheated by up to 1.5-2.0 degrees. Note that the situation yesterday and two days ago projects not only the instantaneous measurements, but also the maximum measured values. It happens in the afternoon, when it knocks out the daily peaks around 3 - 4 pm in my climate. The sun goes lower and lower and warms the largest area of the cover, which correlates with the weak wind.

The results from a few days ago, when the Barani fell again. In addition, the side radiation and weak wind did not serve him in the evening. It overheated steadily by about 0.5, sometimes 0.7 degrees during this time.

This shield needs a strong flow, otherwise it gets a stagnation of warm air and no helix will help here, when the wind oscillates around 0.5 m/s - 2 m/s and we have strong sunshine and unfavorable sun angle. Then it becomes a toy at Apogee TS100 and Davis FARS24H.

I think that I figured out the problem , the batteries were dead in the console , but this would of not caused any issues since it is on a UPS , that is supplemented with a back up generator . The generator had a issue that made the UPS think that it was receiving bad power ( it was ) , after 2 hrs the UPS shut down . I believe that the annual rain is stored on the console . Generator fixed so all should be good after Dec 31 .
