For Erg mode training set the settings to 10s power smoothing in the app. It will feel like a Wahoo or Tacx.
For road racing or ride set the power smoothing to 2s and it will feel like the real deal.

I was surprised to learn how much power tacx and wahoo do to their trainers.


As above tried my drivo on 10 smoothing and it now works fine. When on 2 I had the same problem as all you guys. Give it a go.

As was said on a previous post turn power smoothing to 10. I did and it works ok now

Guys, sorry for the late reply on this topic.

If you think that our previous explanation doesn't fit your specific situation, please contact our customer care.
I tell you this because the first thing we do in these cases is to check the data (to see if there's something unusual) and this is not something we can do in a forum. Here we posted a general explication, but for details or particular situation, the customer care (myetraining@elite-it.com) is the best solution. After that, you can share here the results.

Regards

I posted my concerns directly to Elite customer care about the delay in response on the Direto (and what I am reading here on the Drivo).

All I have had so far is "How are you connecting your ANT dongle?" With a cable I answered.... "Then try it without the cable."

In England we call that a "Chocolate fireguard" response. (Completely useless)

I suggested they actually try the same as I have experienced, with their own kit, but have had no reply.

I am concerned, now reading through the Direto and Drivo forums, that this problem of a 3-4 seconds delay in response to a largish (130-350W-130W) change in power in erg mode has been around for at least 10-12 months. With no resolution. And no intention to resolve.

I am seriously considering returning my Direto as "rejected as faulty" and probably by a Kickr Core, Neo, or even down grade to a smart wheel based trainer. It is a shame, but there is clearly a problem with it. My recent experience of sudden short resistance increases every 20- or 40 seconds has eventually completely undermined my confidence in it. Having demonstrated the power change delay problem to the UK distributors, using their PC/turbo/ant/bike I am convinced it is a product issue and not an individual item issue.

Very disappointed. Great shame. (and I have not even got to the constant errors showing up on the MyEtraining software)

Phil, I have the exact same issue with my Drivo II. I tried changing it to bluetooth, since I thought it could be due to the ANT+ but the delay was even worse. There's no way the resistance can start and stay steady when the interval begins, and some times it stays stuck in a sprint interval way after it's over, when you're supposed to be "resting".
The other issue is with Zwift I'm having is that if I keep a steady cadence on a long interval, the average power seems always to be below target by 15W. It's incredible how much accurate I can be by just disabling ERG, which is a lot to say.
I will try the smoothing suggestion above...

When I see to what is being reported here, the delays in the Directo, Drivo and Drivo II, I'm thinking there would be RF interference issues. I have experienced them with other devices operating on or near 2.4GHz (USB 3.0, ANT, BT, WiFi etc) . My apartment building is very RF noisy with errant signals coming from everywhere.

What helped me a lot was the type of USB cable I ended up using. It's a heavily shielded, active USB3.0 cable for my ANT dongle. I never had an issue with my Drivo lagging, stuck or signal dropouts. Try a better cable and place it as close to the trainer as possible before ruling out that the trainer is the fault. If you have a lot of USB 3.0 devices, get better shielded cabling and shielding for the ports if possible. They are a big cause for a lot of RF interference on 2.4GHz as well. If using BT, turn off as many wireless devices as possible and see what happens. It just may fix your issue.

Guys, I have the same problem with my new DRIVO II. I am testing it since 2 months and tried a lot of different options to repair the issue with watts fluctuations and time of chaning resistance while intervals. I work with AnT+ and Windows PC.

I tried workouts on difrrent gears and cog. It is always the same issue with long time of chaning resitance or just unusual watts fluctuates. You spin normal and suddenly your watts go down for a few secons. It is really annoying.
More over I made research and borrow Wahoo Kickr Core 2018 to check is there a problem with my PC or ant+ drivers etc. And done some workouts. Everything was fine and changing resistance from 100-300 watts took 2-4second max. Drivo takes 10-12 seconds to change resitance.
It was huge difference with Wahoo. No watts flucations while workout having still cadence.

Drivo II TR example workouts - use low gear, and small cog. With high gear and fast interia takes much more longer.
