I bought my Homey somewhere around 2016 i think, first batch.
I have had lot of issues with range with both Zigbee and 433mhz. I have read that many others had the same issues.
We are talking about like 4-7meters on 433mhz and about 8-10 meters on zigbee (free line of sight)
But now I tested my buddies Homey in my home and that works much better.
Also, If I pair my devices (xiaomi and ikea) with the xiaomi controller i have like 20-25meters range.
Q1 : Could there be a Hardware failure from the very beginning that makes my homey have such weak range? Can I check if it outputs enough power to the antennas or run any other diagnostic feature?
Q2: Could it be a software issue?
I have tried to change the channel on my home-wifi to channel 6 with no success.
I live in the country-side with no other wifis around to interfear with the 2.4ghz band.
