Hi all!
I'm running a MEW-01 since 10 months without a problem. A few days ago I started to notice that I don't get data into my home assistant installation via MQTT. I checked the MEW-01 and found it blinking, I think 8 times. 10 minutes later it was up and running again. This happened a few times per day, mostly at noon and afternoon. Some more research showed this happened the last few weeks.
I checked connections power connection, I checked WLAN connection via App and it shows around 60%.
The MEW-01 is used for grid-neutral PV control, this is a pretty severe problem!
Any help would be appreciated!

One more thing I just noticed... Uptime is pretty low and seams to match the time dropouts.

Hi!
I updated to version 2.8.51. But this didn't help...seams like it got even worse. It looks like it restarts, three red leds switch off and on again, than green light blinks one time slow and than 7 times. Is this some kind of blink code?
I just filmed it, link to Youtube via PM.
Thank in advance!

1. Switch the MEW to the configuration mode
2. Connect to MEW's WiFi
3. Open the page 192.168.4.1
4. Read what is in LAST STATE

Maybe your router has some limits or a DHCP server?
Try to connect to a different access point for a test. Preferably one with a nasty network and DHCP turned on.
