Hi,

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.

Any suggestions?

I also have a 2016 Homey and live in a quite small house where Homey is located right in the middle. No more than 8 meters to the farther zigbee device. Yet, without the antenna mod, barely I could reach 3/4 of the devices. Now, I even have a zigbee door switch right outside on the main gate (which is metal, too) and no range issues anymore.

Another good thing to have is a whole hip of zigbee repeaters (those are mains powered devices) I have none of the by the way but the antenna mod helped.

You should try setup your wifi on channel 11 as that would give you the least interference. See here explained Wifi and Zigbee: [https://support.metageek.com/hc/en-us/articles/203845040-ZigBee-and-WiFi-Coexistence](https://support.metageek.com/hc/en-us/articles/203845040-ZigBee-and-WiFi-Coexistence)

Hope this helps a bit.
