Two lights OK, third light intermittently drops off

[jezzaaa]

Weird problem with a newly added light. I'm hoping you can help me work out the source of the problem.

I'm using the Docker instance v0.0.2.6 on a RPi, and I updated the DH and SmartApp a few hours ago. I have two lights working just fine. I added a third light, the same brand as one of the other two, and configured it much the same (different IP, ID and key, of course). However, the ty-connector logs show that strange behaviour in relation to the new light, and I have intermittent dropouts where I can't control the light from ST.

The log shows frequent dumps of the dps values, at a rate of two per second; the other lights don't show these logs (at least not at that rate). After a while the connection to the light drops out, presumably because of the excess traffic. After 5-10 minutes it sometimes comes good again. But sometimes I have to restart the ty-connector docker process.

At the very moment of the disconnect, the light sends a reset:

While it's working, I can turn the light off and on using the ST app, and even from Google Assistant. But when the connection drops out, both of these stop working - but I can control using tuya-cli.
